However, one should be accuracy and the other should be processing complexity. 1. The speed automatic lathe is a kind of automatic lathe with high performance, high precision and low noise, and it is an automatic processing machine tool that controls the processing program through the cam. In addition, there are some CNC automatic lathes, pneumatic automatic lathes and eccentric automatic lathes. Their basic core is to process the same product. Suitable for copper is that it can automatically process the same product for a long time after certain settings and adjustments. It is suitable for the processing and manufacturing of precision parts such as copper, aluminum, iron and plastic, and for the batch processing of small parts, especially complex parts, in industries such as instruments, clocks, automobiles, motorcycles, bicycles, glasses, stationery and military industry, hardware bathroom, electronic parts, connectors, computers, mobile phones, electromechanical industries and military industry. The invention has the advantages of automatic processing, high processing speed, one-time processing and molding of complex parts, accurate and reliable processing precision, automatic feeding and automatic stop after material completion, and high production efficiency.
