If the ordinary lathes and lathes used for a long time are not modified, and only new CNC lathes are purchased, the cost of equipment for many manufacturers will increase. Therefore, it is the only way for manufacturers to carry out numerical control transformation of ordinary lathes and lathes that have been used for a long time.
Because the NC transformation is complicated and chaotic for the transformation manufacturers, how to control the quality of the transformed CNC machine tools is a problem that we have been discussing for a long time.
The CNC transformation of ordinary lathes is divided into new machine transformation and old machine transformation. The new machine transformation is that users buy ordinary lathes or ordinary optical machines (referring to the lathes with only headstocks and vertical and horizontal guide rails), and the transformation manufacturers carry out numerical control according to their requirements. Retrofit. Retrofitting of old machines means that users refurbish and carry out numerical control transformation of ordinary lathes or CNC lathes that have been used. Among them, the transformation of the old machine includes the transformation of the overhauled lathe and the transformation of the user's old machine parts. In this paper, we briefly discuss the quality control method, focus on control points and inspection process of CNC lathes in mechanical aspects.
