Made CNC punch technology great progress

We need to have been competitive products, technology, domestic CNC punch technology is now a great progress, but compared to foreign CNC equipment technology, there are gaps in all aspects of CNC punch products, so the domestic CNC equipment technology breakthroughs, we What should I do?

We can find, we are now in the production of CNC punch technology has a very large space for development, the level of CNC machine tools, variety and production capacity, a direct reflection of a country’s industrial strength, and the birth of CNC machine tools in China than in the United States, Germany, a slight lag, nearly half of the world’s development experience in CNC machine tools behind China in Germany, the United States, Japan and other countries, the domestic CNC machine tools basically low-budget and medium-term popularity of CNC machine tools in the market share 70% -80%, numerical control system (90% affordable, advanced type) of foreign occupation.

The above data is not that we do not have competitive CNC equipment competitive, relative to the large-scale production of domestic CNC punch equipment market advantage small and medium-sized manufacturers, market research can find us in the NC punch and mid-range strains, CNC punch equipment in China Already have a certain strength, only in the high-end equipment manufacturing is still short board, and so in the choice of high-end CNC punch press we will prefer foreign products many times.

In 2014, the state will continue to grow steadily, adjust the structure, in this environment, the CNC punch industry must adjust the industrial structure, punch manufacturers exist in the existing power is based on high-end results in the end, on the one hand, need to face Foreign products, joint venture products out of the domestic mid – range market competition pressure, on the other hand, stepping up research and development in the high – end market, get rid of the serious situation of discipline by others.

In 2014, steady growth, based on the expected growth in the import demand for CNC punch presses in China in 2013 is still very large, but the demand for high-end products to the more partial, at the same time, after the implementation of local market services Of the final product in foreign countries will also increase.

Maintenance and Maintenance of Press Bench

Machine maintenance and repair

1, in order to prevent mechanical deformation of the table, while lifting the four pillars at the same time, the length of the wire rope and the machine on the four heavy holes, smooth lifting in the transport.

2, machine table support pad, pad, to ensure that the support of the uniform stress, to ensure stable working platform.

3, the machine table will be installed at each support point adjustment mats mats, pads, adjusted by the professional and technical personnel to qualified accuracy.

4, the machine table for light workpieces, not rough when the workpiece, so as to avoid surface damage caused by bumps and scratches.

5, in order to prevent the overall deformation of the workpiece, the use of the workpiece, to remove the workpiece in order to avoid deformation of the workpiece caused by the weight of the workpiece is very long.

6, the machine table does not require timely cleaning, and then coated with a layer of anti-rust oil, and covered with rust-proof paper, with the outer cover will be covered to prevent the normal surface of the punch is not pay attention to the damage.

7, machine table should be installed in a ventilated, dry environment, and away from heat, corrosive gases, corrosive liquids.

8, regular inspection week for the implementation of national standards for machine tools, test cycle according to the specific circumstances of 6-12 months.

Precision punch factors affect the performance of sports

High-end machine tool market At present, we also rely on a large number of imports of punch to compensate for this vacancy, “ultra-precision machine tool R & D and manufacturing technology is a cutting-edge technology, will lead the machining accuracy of human technology has not been involved in the field of deep “Ultra-precision machine tools are developed and take measures to take control of the machine, and it embodies a national precision technology competitiveness. “This is the goal of China’s machine tool industry, the” ultra-precision machine tool is developed countries attach great importance to and take measures to control the machine, and it embodies a national precision technology competitiveness. “Analysis of professionals, said that there is no hysteresis bearing technology, there are many mechanical systems in the hysteresis phenomenon, hysteresis not only seriously affect the board positioning accuracy and repeatability of precision machine tool sliding movement, but also affect the high-resolution movement to achieve , But also affect the accuracy of the parts shape and surface roughness of precision machining.Hydraulic technology can solve the mechanical hysteresis phenomenon, and can be in the geometric error in the ultra-precision machine tools for a large number of applications.Hydraulic technology in the past ten With the improvement of flow control technology, the rigidity of hydrostatic bearing has been greatly improved, so that the hardness of ultra-precision machine tool is continuously improved, and the other one is more and more mature. The key technology is the application of high-resolution driving technology and micro-vibration processing technology in mechanical system.Nano-scale resolution is the characteristic of ultra-precision machine tool in the past decade, and many factors affect the performance of motion.
At the same time, a large number of experimental studies have found that vibration signals of the order of 10 nanometers exist in many mechanical actuators, the realization of mechanical sensitivity and measurement of interference, this vibration is called micro-vibration. Depth study of the mechanism of micro-vibration, ultra-precision machine tools to find ways to solve the nano-precision. The development of ultra-precision machine tools and manufacturing technology is an advanced technology, so that the accuracy of the machine tool to the people do not continue to technology involved in the development of high-end machine tools, The field of further progress. “In the accuracy of the machine from micron to nano-scale course of development, there are three key technologies can not be avoided, these three technologies are nano-precision machine tool research threshold. “This is the goal of China’s machine tool industry.” The mechanism of micro-vibration in-depth study, and seek solutions to ultra-precision machine tool is the only way to nano-precision. (Partly from China Machine Tool Network) high-end machine tool market at present we also rely on a large number of imports to fill the vacancy, “ultra-precision machine tool R & D and manufacturing technology is a cutting-edge technology, will lead the machining precision “The ultra-precision machine tool is a machine tool that is very important in developed countries and takes measures to control it, and it embodies the competitiveness of a state-of-the-art technology. “Analysis of professionals, one of the technology is not lag axis bearing technology, there are many mechanical systems lag phenomenon, hysteresis not only seriously affected the accuracy of the machine movement and positioning accuracy of repeatability, but also affected the high-resolution movement, But also affect the accuracy of precision machining parts and surface roughness, while the hydrostatic bearing technology can solve the mechanical hysteresis phenomenon, and can be geometrical errors in the ultra-precision machine tools for a large number of applications.Hydraulic technology in the past decade has made Great progress, self-compensation feedback technology is more mature.With the improvement of flow control technology, hydrostatic bearing stiffness has been greatly improved, so that the ultra-precision machine tool material hardness continues to increase.Another key technology is high Resolution drive technology and micro-vibration machining technology in mechanical systems.Nano-resolution is the characteristics of ultra-precision machine tools in the last decade, and many factors affect the performance of motion.At the same time, a large number of experimental studies have found that 10 nanometers Vibration signals exist in many mechanical actuators, the realization of mechanical sensitivity and measurement of interference, this vibration is known as micro-vibration .In-depth study of the mechanism of micro-vibration, ultra-precision machine to find solutions to nano-precision approach.
