As a high-efficiency metal cutting equipment suitable for large-scale parts processing, broaching machines are mainly used in automobiles, motorcycles, agricultural machinery, aviation and construction machinery and other industries. The unreasonable structural design of some products, improper use of materials and heat treatment, and imperfect detection methods also directly affect the geometric accuracy and processing accuracy of the broaching machine itself.
CNC Tool Introduction Broaching
As a high-efficiency metal cutting equipment suitable for large-scale parts processing, broaching machines are mainly used in automobiles, motorcycles, agricultural machinery, aviation and construction machinery and other industries. The unreasonable structural design of some products, improper use of materials and heat treatment, and imperfect detection methods also directly affect the geometric accuracy and processing accuracy of the broaching machine itself. As a high-efficiency metal cutting equipment suitable for large-scale parts processing, broaching machines are mainly used in automobiles, motorcycles, agricultural machinery, aviation and construction machinery and other industries. Although its proportion in metal cutting machine tools is currently only 0.8% - 1%, due to its high processing size and shape position accuracy, convenient operation and maintenance, low processing cost and easy automation, the application range of broaching machines is increasingly extensive. The process range is also extended from general inner hole and plane broaching to more complex profile machining.
my country's broaching industry can be traced back to the "Changsha Inserting and Pulling Planer Research Institute" established by the former Ministry of Machinery in Changsha Machine Tool Factory in the 1950s. After more than half a century, domestic broaching products have changed from imitation of former Soviet Union products to self-made products, and enterprises have also developed from one fixed-point production at that time to many coexisting. It is understood that one process of broaching can completely replace the traditional three processes of milling, grinding and planing. However, due to the slow development of domestic broaching technology, it has not been well promoted, so broaching machine tools have always been in the gold cutting machine tool. non-mainstream status. The overall structure, auxiliary devices, and general accessories of the broaching machine are still at the level of ordinary design, manufacturing and processing, lacking independent and advanced scientific design, manufacturing, and after-sales technical service capabilities. Restricted by the domestic numerical control, electrical, hydraulic, pneumatic, cooling and other supporting components, the functional compounding and automation level of the broaching machine is also relatively low.
