The further development of China's broaching indus

The further development of China's broaching industry needs to pay close attention to R & D and technology

Abstract: some insiders said that compared with the machine tool industry, which has entered the international forefront, especially the drilling and boring machining centers, China's broaching machine manufacturing is still at the world's second and third class level. With the increasingly fierce competition in automobile and other manufacturing industries, the requirements of broaching machine for accuracy, efficiency, flexibility, reliability, versatility, environmental protection and so on are also getting higher and higher

as a metal cutting equipment with high efficiency and suitable for mass parts processing, broaching machine is mainly used in automobile, motorcycle, agricultural machinery, aviation, engineering machinery and other industries. Although its proportion in metal cutting machine tools is currently only 0.8% - 1%, due to its high accuracy of machining size and shape position, convenient operation and maintenance, low processing cost and easy realization, the former has a large gap and is now automated, the application range of broaching machine is increasingly extensive, and its process range is also extended from general internal hole and plane broaching to more complex surface machining

it is understood that one broaching process can completely replace the traditional three processes of milling, grinding and planing. However, due to the slow development of broaching technology in China, broaching machine tools have been in a non mainstream position in metal cutting machine tools. Therefore, the further development of China's broaching industry needs to pay close attention to R & D and technology

these differences are embodied in the following aspects: first, the backward means of product design and the poor technical reserves of products. The design of broaching machines in China basically adopts the traditional manual empirical calculation and analogy method, which is slow and easy to make mistakes, affecting the development progress and product quality of new products. However, some manufacturers are satisfied with the existing market, lack the long-term strategic goal of using, developing and developing a generation, and have poor self-development ability to find and solve problems

secondly, the overall structure, auxiliary devices, general accessories, etc. of the broaching machine are still at the ordinary level of design, manufacturing and processing, lacking independent and advanced scientific design, manufacturing, and after-sales technical service capabilities. Restricted by domestic CNC, electrical, hydraulic, pneumatic, cooling and other supporting components, the function compounding and automatic water of broaching machine can show the experimental curve level in real time is also relatively low

in addition, unreasonable structural design of some products, improper use of materials and heat treatment, and imperfect detection methods also directly affect the geometric accuracy and machining accuracy of the broaching machine itself

some insiders said that compared with the machine tool industry, which has entered the international forefront, especially the drilling and boring machining centers, China's broaching machine manufacturing is still at the world's second and third class level. With the increasingly fierce competition in automobile and other manufacturing industries, the requirements of broaching machine for accuracy, efficiency, flexibility, reliability, versatility, environmental protection and so on are also getting higher and higher

obviously, the pace of domestic enterprises is also accelerating, and on the basis of ensuring the accuracy and surface roughness of supporting parts, they are constantly improving work efficiency
