  In recent years, the domestic crane emerge in the international market, the mainstream enterprises lead the industry upgrading, technological breakthroughs. Review the course of growth: from 2000 to 2005, the global crane industry in compound annual growth of 25% more than the high speed growth period. Among them, China's contribution to the largest incremental, truck crane sales from the beginning of 1999 doubled, in 2003 exceeded 1 million units, China has become the largest crane manufacturer in the world. In the meantime, mainstream enterprises to achieve the two key breakthrough, one is production capacity exceeded 1 million units, second is innovation to adapt to Chinese demand below 100 ton crane technology, overcome all terrain crane core technology, forming a cover low-end high school Chinese School of technology, the special key, it established the Chinese crane unique price advantage. At present, China heavy machinery and equipment production enterprises reached more than 3500, which 1898 companies have installation, demolition permits, they have more advanced manufacturing capabilities, the "Twelfth Five Year Plan" period, heavy machinery products of the total value of industrial production and sales revenue, respectively per year increase of 30%, but the product in general and foreign or larger gap. From 2005 to 2010, the macro environment has an important change: countries to increase investment in infrastructure construction, energy and other construction projects led to the large hoisting the technological innovation, the mainstream companies to achieve three major breakthroughs: internationalization speed, the second is the crane product structure and product categories are further subdivided, type spectrum span from 5 tons to cover 2000 tons, with car, car, the whole ground, crawler, off-road tire type development; three is large. China crane largest tonnage 200 tons of history is broken, the global crane industry completed the span from 100 tons to kiloton. From 2010 to 2013, the tightening of macroeconomic environment, but the supply capacity increased by nearly two times, mainstream enterprises, on the one hand to deal with all kinds of competition pressure, also catch the structural changes of the area, realize the second international take-off in the strategic layout, the layout of product and technology quickly seize large tonnage to highs, Chinese enterprises once again demonstrated the advantage, one of "the world" are or are about to be born, and a wheel in order to enhance the user the use value is the theme of a new generation of technology revolution is on the rise. Future development trend At present, lifting machinery is in the market at a high speed development period, there is a great market development potential. With the rapid development of modern construction, the requirements of the lifting machinery is also getting higher and higher, and the development of the trend of hoisting machinery to large scale, automation and specialization. 　　Large scale Since the beginning of the new century, the trend of large-scale projects to accelerate, the domestic super crawler cranes began to appear in front of people. 1000 tons, 2000 tons of crawler cranes have been launched, opened a prelude to the rapid development of China's super crawler crane. Currently on the crane market, the largest sales of 5~8t products, accounting for more than 50% of total sales. Due to the large number of manufacturers, the price competition intensified, product profit margins increasingly narrow, while the profit margins of large tonnage products far more than small and medium tonnage products. From the point of view of the development direction of domestic automobiles chassis, large tonnage truck market growing rapidly, FAW, heavy truck and other manufacturers are in speeding up the development of large tonnage truck chassis, so large tonnage overhead traveling crane products will as large tonnage chassis market expands gradually increase, the 2011 10t products accounted for total sales of less than 30%, this year on half a 10t of above products accounted for 33% of the total sales volume, in the next few years, a series of large tonnage bridge crane products will have a larger space for development, the demand is gradually increasing trend. With the construction of large-scale projects, the lifting and transportation of materials for lifting machinery to provide a more broad space for development, market demand continues to grow, the industry outlook. automation The rapid development of hoisting machinery industry has greatly promoted the application of automation products in the industry. Although the overall level of automation applications in China's lifting machinery industry is not high, but whether it is the lifting machinery manufacturers or lifting machinery users are gradually aware of the advantages of the application of automation products. Luo Wenlong China Academy of Building Research Building Mechanization Research Branch Technology Center Director, said automation products application potential in the lifting machinery industry is huge, prospects are very broad. Both the city to more mature and modern form of development trend, or economic crisis, countries in the infrastructure stimulus spending, showing the flourishing development of hoisting machinery. From control to transmission, the application of automation products in this industry is also increasingly accumulated. From the point of view of the existing scale, space for future growth and the current growth rate, heavy machinery industry has gradually become the market of automation companies should not be overlooked. specialized With the national electric power, petrochemical, steel, transportation and other infrastructure construction into the climax, the rapid expansion of the domestic crane market, the large crane trend has become an irreversible fact. In order to reduce the production cost, save manpower and material resources, the demand for large cranes is gradually expanding, and the requirement of the crane is more and more large. The lifting speed of the increasingly high demand, must on energy consumption control and crane performance requirements more and more high. As one of the most important part of the automation production process, simple operation, high safety, reliable performance, easy maintenance is a basic requirement of the crane. In addition, the price of high play heavy machinery will be more in the future market. To this end, to meet the needs of a variety of professional cranes are constantly being developed and put into use, there are nuclear power, paper, garbage disposal and other special crane. The special performance of the crane can also meet a wide variety of working environment, such as anti-corrosion, explosion-proof, insulation crane, etc.. The performance of traditional railway and ship special crane is also increasing, and the adaptability to the environment is also increasing. Can imagine, with the urbanization construction in cities and towns across the country continue to expand and accelerate the development, including aspects of railway transportation, construction, energy, water and so on many engineering construction, and to the development of Chinese crane industry provides a more broad prospects for development. The next 3 to 5 years of time, the crane market in China will be more wonderful, 100 tons to kiloton product spectrum will be more intensive, technology will be more mature, people will gradually from the initial to Chinese enterprise series of breakthroughs in the "world's largest" surprise calm down, more deeply integrated into engineering application and user requirements. 　Face China heavy machinery industry development momentum is good, we should pay attention to the mechanical technology is presented in this paper. Lifting machinery and equipment of sustainable development strategy, although China has to enter the high-end, but of independent innovation, establish their own brands, to promote the development of the strategic, lead with innovative development to do a good job ability oneself so that the industry's long-term development, set up intellectual property rights awareness should be strengthen the cultivation.

• Risk and development ...

  Industrial automation equipment belongs to intelligent equipment is the "12th Five-Year" during the state key development of strategic emerging industries (October 2010 "State Council on accelerating the cultivation and development of strategic emerging industries"). However, in the development of industrial automation equipment industry, there are some risks, and in 2015 a new development trend. 1, market risk. The number of domestic manufacturers of industrial automation market many multinational companies occupy most of the high-end market, and domestic enterprises except a few of the larger companies, the majority of small and medium-sized enterprises mainly in the low-end market competition, leading to more intense competition in the market. Next, as new entrants into the enterprise, industry competition further intensified, the industry will have a negative impact on the profitability of existing companies. 2, technical risk. Industrial automation industry with high technical content, industry with large international companies in the field have very deep technical accumulation, and continued to maintain a higher R & D investment, domestic enterprises although after 20 years of development, in some areas has been gradually catch up, but in some key components and parts manufacturing and international manufacturers still exist large gap. Next, the domestic enterprises such as the gap between technology research and development and the gradual narrowing of the national manufacturers, it will always be in the industry value chain downstream, in the competition in a disadvantageous position. 3, the industry chain is not perfect risk. Domestic industrial automation industry chain is not perfect: affected by the traditional system and the concept, industry still exists "heavy research and development, light industry" the tendency, many technological achievements out of the test room and was eventually shelved; state investment funds are limited, enterprises and research institutions lack of capital operation, investment risk consciousness and ability; and industrial automation related to the processing of raw materials and components manufacturing industries, low level of technology, it is difficult to provide support. And abroad in the field of industrial automation, basic research, industry, manufacturing has formed a complete set of system: many multinational R & D institutions in countries and regions in Europe, America, Japan and other developed science and technology, talent and technology intensive; the industrialization in China Taiwan, Singapore and other places, these regions have a large number of early to do OEM started enterprise, the basic technical transformation for the sophisticated products has accumulated rich experience, while the cost to much lower than Europe and the United States,; when the product enters the stable, high-volume manufacturing jobs into design in China, Malaysia, Indonesia and other lower cost of developing the factory to complete. The industry chain is not perfect and has a negative impact on the long-term development of China's automation industry. Development trend Industrial automation equipment belongs to the category of intelligent equipment. It is during the "Twelfth Five Year Plan" national key support for the development of strategic emerging industries (2010 October "the State Council on accelerating the fostering and development of strategic emerging industries of the decision"). In the next five years, with the demographic dividend disappeared and raw materials, energy costs rise, China's manufacturing industry will experience from extensive, low value-added model to the intensive, high value-added model of historical change. As a high-end manufacturing industry "cornerstone", industrial automation equipment facing the transform and upgrade traditional industries and emerging industry development needs double opportunities, which we judge the two remarkable growth line will appear in the industry: 1, accelerate the growth of high-end smart equipment: the penetration rate of inverter in CNC machine tools, process automation system, has a higher products such as growth is slowing down, but with low labor costs, industrial upgrading accelerated upward into the white hot stage, "artificial" attributes stronger, lower permeability of the early "high-end smart equipment (such as industrial robots, automatic assembly line, automatic warehousing equipment etc.) is expected to cross the product introduction period, entered a high-speed growth period. 20-30% has maintained an average annual growth rate of the next 5 years. Leading local automation rise: benefit developing countries support localization rate promotion policy intentions, key parts of the breakthrough, grasp the core technology, strong R & D capabilities and domestic enterprise automation equipment) is expected to accelerate the pace of import substitution. To achieve more than the average of the rapid growth of industry. [詳細]

• Automation equipment st...

  "Soaring labor costs are forced manufacturers to upgrade the manufacturing sector, which allows the robot to automatically stand on the outlet." Last year, Shandong Sam automation equipment Co., Ltd., general manager of Qiu Hongbo and his partner together through the shuangchuang reign a rapid development. "Made in China 2025", the United States "re industrialization idea", Japan "industrial intelligence" and the German "industrial 4" and other hot search words so that more and more people understand the industrial robot automation. Qiu Hongbo said, the traditional industrial enterprises now sad day, away from the market more nearly have the greater impact, but robotic automation has ushered in the rapid development, standing in the air, Sam automation such as start-ups with good time completed the accumulation of technology. Sam automation equipment company has done more than ten years of construction machinery, from April 2014 to start the main industrial robot system applications. Asset light operations automation Sam, in a short period of time more than a year, not only won the Foton millions of dollars of orders involved in the business Shandong, Hebei, Fujian, Hubei and other places. In the double background, technical cooperation between universities and enterprises more smoothly, it is impossible to imagine in the past." Qiu Hongbo told reporters that the company in the past in the use of "brain" in the process, colleges and universities are generally reluctant to cooperate with private start-ups, especially joint technology development. Domestic colleges and universities in the industrial automation has a wealth of technical reserves, is often more theoretical, in the pursuit of scientific research is too advanced and experimental, ignoring the market demand, the enterprise is just its complementary. Qiu Hongbo said Sam R & D this year a robotic arm stamping technique involves, past companies rely on the company's own technical team to complete the development of at least half of the time, after and the cooperative development of the Hebei University of technology, only about 2 months time has been completed, push the products into the market on schedule in advance greatly, enhance the competitiveness of enterprises. "Company application of industrial robot system is less than 2 years of time, or is accumulated in the investment stage, although robotic automation in the capital market is very hot, there are many investors to talk about the investment, but are still cautious." Qiu Hongbo said 2015 focus on the domestic market, the project of standardized design more, 2016 prepared with the help of the industry of tuyere, expand the team size, will have been forming module technology, try peers involved in the export of the automation, in the competition is not fierce blue ocean force. As an entrepreneur, Qiu Hongbo last year, the most real feel the hot business circle. At most, about a month or so, Qiu Hongbo attended the 5 business forum or summit, you can say that there are activities. This is not he participated in various exhibitions and promotion will and professional automation business exchange, part of these activities more or less and entrepreneurial detached. A few years ago, the business circle has been lukewarm not fire, did not expect this year's sudden outbreak of all kinds of resources on the unprecedented attention of entrepreneurs, the circle of friends every day on the innovation and entrepreneurship information brush non-stop. Our start-up enterprises in the industry's influence is limited, with entrepreneurial circles concern not the past, and many investors, automation, networking start-ups have a lot of contact, harvest a lot.

• Chinese manufacturing i...

  In Boao Forum on China's development of the manufacturing industry, in fact, is not a trivial matter. Before just died shortly before Intel chairman Andy Grove had said that America now faces a to the task is to reconstruct the system of basic industries, he believes that companies in the United States in the pursuit of their own goals, not the forget oneself is also charged with the responsibility for maintaining the national industrial base, because industrial base in consumer spending and social stability based. The above analysis shows the importance of the manufacturing industry, which has a reference value for china. If China wants to continue to be a solid economy, it is necessary to make a "world factory" manufacturing industry. To this end, Chinese to reach the level of industrial development in 4, estimates it will bite the stem 20 years! China's economy in the "real" is an indisputable fact, manufacturing transfer, shrinking and exit in the country a large number of. This essentially means that the "world factory" in China is gradually fading. Has China passed the stage of manufacturing? Obviously not, China is now not only to engage in manufacturing, but also to continue to promote the transformation and upgrading of the manufacturing industry. As an independent think tank of Anbound consulting (Anbound) in more than four years has previously suggested, if China has in the past is the factory of the world "version 1.0", then future goal is to do the factory of the world "version 2.0", in the front and more advanced "world factory version 3.0", "world factory version 4.0", "world factory version 5.0", Japan, Germany, the United States living in high-end manufacturing. At the beginning of this view in this year's Boao forum has been confirmed. Domestic long been engaged in manufacturing of TCL chairman Li Dongsheng said that in accordance with the standard German, TCL's color TV factory, a cell phones factory can reach the industrial 2.0, "2025 has 30 years of the cycle of China's manufacturing, the goal is to the whole of China's industrial competitive capacity reached the world leading level. This is only the first phase of China's industrial transformation and upgrading of industrial capacity, the real transformation and upgrading of China's manufacturing, China from manufacturing power into a manufacturing powerhouse, the future is still a long way. Li Dongsheng also said that China has a large number of factories in the industrial 2 phase, from 2 to 3.5 of the industry, and then to 4, China has a long way to go. Heraeus (Heraeus) Group Chairman Ling Rhett at the forum also said that if China is to achieve industrial 4.0, the evolution process need 10 years or even 20 years time, "this is the industrial revolution".

  High precision position control is the key technology of developing high precision NC machine tool. In recent years, we according to the needs of the development of domestic high precision CNC machine tools, to fully digitized closed loop high accuracy position control technology were studied taking the opportunity of development based on a new digital closed loop position control system, and has carried on the application in a variety of domestic CNC machine tools, in the complex precision machining parts achieved good results. The basic composition, dynamic structure, controller design and application of the new system are introduced in this paper. High precision position control is the key technology of developing high precision NC machine tool. In recent years, we according to the needs of the development of domestic high precision CNC machine tools, to fully digitized closed loop high accuracy position control technology were studied taking the opportunity of development based on a new digital closed loop position control system, and has carried on the application in a variety of domestic CNC machine tools, in the complex precision machining parts achieved good results. The basic composition, dynamic structure, controller design and application of the new system are introduced in this paper. Conventional digital position control At present, the digital AC servo system is getting more and more extensive application in the numerical control machine tool. The basic components of the position control system composed of the system are shown in figure 1. The digital servo drive module and the servo motor are combined together to form a high precision angle close loop servo system, whose input is the instruction pulse given by the numerical control system, and the output is the rotation angle of the motor. In the closed loop to achieve optical encoder as the feedback control, rotation of the motor shaft will strictly follow the instruction value change. The angular displacement of the motor is converted to the required working table linear displacement through the gear pair and the screw nut pair transmission. From figure visible, although the corner for the output of digital servo system is a closed loop system, but from machine worktable displacement as the ultimately controlled the amount of perspective, composed of the position control system is an open-loop system (or semi closed loop system). Therefore, its position control accuracy is not only related to the performance of the control system, but also to a large extent depend on the mechanical structure of the machine tool. So system information transmission link error, mechanical transmission link error and all kinds of nonlinear factors influence will deviate from the command value of the displacement of the worktable, and open loop system and unable to carry on the effective correction, which makes conventional NC machine, bed even the use of a high performance digital servo system is also difficult to achieve high machining accuracy. Two, digital full closed loop position control system In order to solve the above problem. In this paper, a digital closed loop position control method, the basic idea is; on the basis of movement of the machine tool parts of digital drive, the introduction of ultimate displacements of direct detection of moving parts of digital measuring link, to full access to and use of information system, from the angle feedback control of the movement of the machine tool coordinate of digital control, which contains the various sources of error and non-linearity of fully digitized closed loop system. So that the system can not only make the positioning precision of the moving parts is decided by the detection part of the measurement accuracy, but also impact on various kinds of interference and nonlinear factors on the displacement of the moving parts of effective dynamic correction, the actual displacement of any moment of moving parts always strictly follow the command value changes, so as to ensure the movement of the machine tool coordinate has a high dynamic and static accuracy. According to the above ideas, the basic composition of digital closed-loop position control system is shown in Figure 2. The system using grating as line displacement detection device direct access to the worktable displacement information. This information after preprocessing phase difference 90 degrees of two displacement pulse signal, the frequency and the worktable displacement is proportional to the speed, the number of working table actual displacement divided by the pulse equivalent. The displacement pulse is sent to the counter to count, and the count value of the counter indicates the current actual position of the working table. Position controller in the system, according to the position setpoint and position feedback value difference and control the operation of the whole system according to the pre designed digital control law, to ensure work platform displacement strictly follow the instruction value changes. Three, the dynamic structure of the system and controller design The dynamic structure of the system is shown in Figure 3, including digital position controller, generalized object and feedback channel 3 parts. The generalized object consists of zero order holder, pulse generator, digital AC servo system, mechanical moving parts and so on. Among them, the zero order holder plays a link discrete (digital controller) and continuous link bridge style. The task of the pulse generator is to control the operation of the AC servo system based on the control signal given by the position controller. AC servo system is a system of digital driving device, from a macro perspective, servo motor angle theta and instruction f between the integral relationship between the frequency of the pulse, but from the micro should further consideration of the theta and f the inertial properties. The role of mechanical moving parts is to convert the motor angular and linear displacement, if the transmission error and nonlinear factors as the system dynamic disturbance, the link will be look as a proportional component. In this way, after proper treatment, the generalized object representation for the transfer function of feedback channel though, including detection device, pre processing, information transmission, reversible counting, and so on many aspects, involving more complex information processing process. But in the actual position from the input, the position feedback value (reversible counter of meter value multiplied by a pulse equivalent) look for the output point of view, the feedback channel watch as a proportional component, through proper design can make the transfer function of GF (s) = L. Considering generalized object to contain a integral part of third order system, to make the closed-loop system has a fast dynamic performance. And tracking ramp input zero steady-state error, PID regulator is used as a position controller, realization algorithm for: In the UK, the K sampling period of the controller output EK -- the K sampling cycle of the input and output of the system between follow error KP, proportional coefficient of Ti, integral time constant TD, differential time constant of the PID control system for E type system, found the actual debugging, the system dynamic process of ultra tune are often large, sometimes even can not work normally. In order to solve this problem, the integral action of (2) - type is separated and controlled. When the system is in the transition process, tracking error is larger, the cancellation of the integral control, so that the system for the I type system, to ensure stable operation. When the system enters the steady state tracking process, the integral control system is added to the K type system to ensure that the steady state error of the tracking slope input is zero. Thus obtained control algorithm for type in the Delta, the steady-state tracking interval for further improve control performance, using computer to achieve the flexibility of the algorithm for digital, variable parameter control in (3) on the base, namely according to the different stages of the operation of the system and the algorithm parameters KP, Ki and KD were taken different values, in order to obtain better control effect. Four, experiment and Application After the system prototype is completed, the motion experiment is carried out on a SK8140 CNC milling machine. The machine tool X, Y and Z are all driven by a digital AC servo system, and a grating ruler with a resolution of 0.005mm is installed as a displacement detection device. Experiments with 50mm pitch on the working table stroke length to determine a certain number of test points, and then let the table in the system drive control on these points positioning and 6 times every point positioning and locating each time for a measurement. Test results are: The difference between the measured value and the instruction value at each point is not more than 0.01mm. This shows that the digital closed loop position control system has good position control precision. So far, the development of digital closed loop position control system has been applied in dozens of domestic CNC machine tools. The machining accuracy of the new type of fully closed loop NC machine tool is obviously improved, and the accuracy is very good, and good results have been achieved in the complex die parts and precision hole machining parts. Five, conclusion In view of the demand of the development of high precision CNC machine tools, the new digital full closed loop position control system is studied: (1) digital drive the movement of the machine tool parts, not only can effectively eliminate the influence of the temperature drift, zero drift, and can make the controlled object has ideal dynamic structure, the digital closed loop system of which the dynamic performance is the basic guarantee. (2) the ultimate displacement of moving parts of digital detection, real-time access to moving parts of the accurate locations information is effectively suppressed mechanical transmission error and nonlinear factors on the movement of the machine tool coordinate precision laid a foundation through the whole closed-loop control,. (3) is the application of computer digital position controller, can be implemented by software with switching logic of complex control rules, make full closed loop position control system has excellent dynamic and static performance, so as to improve the contour machining accuracy of NC machine tools. (4) the practical application shows that the numerical control machine tool which is controlled by the digital full closed loop position control system has good effect on the machining of complex precision parts.

• Processing high quality...

  In a large engine block, there are generally 20 to 40 threads. It is easy to find the connection between the parts and components in the crankshaft, the cylinder head, the connecting rod and the stamping and die forging parts of the whole vehicle. In mechanical engineering, the shell, the bearing and the wheel hub also have a lot of thread connection. Especially in mass production, such as in the automotive industry, rapid and reliable manufacturing these threads is crucial, especially in connection with the end of the thread and the manufacturing process of parts, when a lot of processing time was invested in each of the parts, if nonconforming parts will become expensive things. Greatly improve the efficiency of the high-speed screw extrusion Taps Considering the actual condition of these applications, Walter company in this year's emo trade fair exhibited a new whole hard alloy extrusion tap Protodyn HSC. The extrusion tap is included in the range of high speed cutting tool, so that it can reach twice the extrusion speed of conventional HSS (high speed steel). Field experiments in a number of companies have shown that the squeezing screw threads taps in terms of performance has reached a new height. For an extrusion part, using a screw extrusion Taps formed the number of threads, using the original tool 20000, Protodyn? HSC reached 90000. This showed that the tool life is improved by 3.5 percent. The cutting speed, or more precisely, the extrusion speed is doubled. In addition, with two hours of saving the time to process 90000 threads. For a link, and use the original screw extrusion Taps compared to Protodyn? HSC tool life extended 300 percent. In the crankshaft, the number of threads is almost 4 times, the tool life is increased by two hundred and eighty percent, the processing time is shortened by twenty-five percent. Walter company responsible for thread manufacturing production manager Timo Mager said: "tool life up conventional HSS (high speed steel) three times, the benefits far higher than for the new Protodyn? HSC pay relatively high purchase price." He also unveils the successful reason: "a new development of matrix, an innovative cutting groove and the optimization of the extrusion forming blade angle shape extrusion - the three innovation together produced Protodyn? HSC in the significant advantages. Whole hard alloy thread extrusion tap matrix by the micro grain varieties with high hardness and high toughness composition, which makes the thread extruding tap to obtain the high stability. The new cutting grooves mean that all of the extrusion dies of the cutting tool can be evenly participated in the extrusion process, which leads to a more uniform distribution of wear than the original cutting extrusion process. Only the process has extended the tool life by seventy-five percent. Finally, extrusion extrusion edge new polygonal reduces the friction between the tool and the material and heat generation, to further improve the tool life. Figure 3 considerable improvement in tool life: New HSC? Protodyn can process 3 multiple purpose threads. Advantages of screw extrusion As a result, the new HSC tool represents a real bright spot in the field of screw extrusion, and it provides its own advantages over the thread cutting. In the first place, the extrusion forming process does not generate any chips, so the problem of chip packing is eliminated completely, and the process of the screw extrusion is not easy to be affected by faults. For this reason, it is more willing to use the screw extrusion to form the deeper thread. Another advantage is that it can process a high quality thread. In the extrusion process, the parts of the material fiber is compressed, not in the cutting process is removed. As a result, the thread has a better structure and a better surface quality. This has a very beneficial effect in the threaded connection, which is mainly in the case of dynamic load conditions, such as the vibration of the motor. The tensile strength of the extruded thread is twenty percent to thirty higher than that obtained by the cutting process. Nature of the work of the vehicle and machinery have a favorable effect. Screw extrusion tap tap than damage slowly, this is because the tap requires spiral chip chip removal. Therefore, the cross section area ratio of extrusion tap tap, the process is more stable. Walter company product manager Timo Mager praised said: "so in some industry sectors, does not always screw extrusion that is an alternative to the thread cutting process," he is also aware of the "whole hard alloy thread extrusion Taps have some degree of sensitivity, so people are more willing to adopt the HSS (high speed steel alloy) tool." Wide application range However, with the advantages of HSC Protodyn, the advantages of screw extrusion will be fully revealed, especially in mass production. In this case, the time and speed are the most important. In the automotive industry and similar mass production departments, the new thread extrusion taps can really play its potential. This method can be considered for all metal materials which can be used for mold processing, so it can be widely used in silicon components below twelve percent of steel, stainless steel and aluminum alloy materials. When the pitch is 1.5 mm, the tool achieves its best effect. HSC Protodyn to provide a variety of varieties. According to the thread of use, can be used with or without cooling extrusion taps. The lubricating groove, extrusion taps can be generic, especially for deep thread over 3xd. For applications that do not require a lubrication groove, lower prices can be used. Because there is no need to discharge the same chip, extrusion taps can be used for basic thread and thread through hole. In applications requiring continuous machining of large amounts of threads - such as the application of a machining connecting rod, a non-standard tool is required. Walter Inc can be specialized in the need to process the thread configuration, which is the cooling, lubrication and cutting groove special configuration. [詳細]
