Če se navadne stružnice in stružnice, ki se uporabljajo dolgo časa, ne spremenijo in se kupijo samo nove CNC stružnice, se bodo stroški opreme za številne proizvajalce povečali. Zato je edini način za proizvajalce, da izvedejo numerično krmilno transformacijo navadnih stružnic in stružnic, ki so bile v uporabi že dolgo časa.
Ker je NC transformacija zapletena in kaotična za proizvajalce transformacij, je kako nadzirati kakovost transformiranih CNC obdelovalnih strojev problem, o katerem razpravljamo že dolgo.
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.
