The machining precision of automatic numerical control machine tool is high

Fully automatic CNC machine parse fully automatic CNC machine machining precision of high precision nc machine tools in general can be up to 0.05 0.1 MM, nc machine tools is according to the form of digital signal control, numerical control device every output a pulse signal, the machine moving parts move a pulse equivalent (0.001 MM), and machine tool feed drive chain of the reverse clearance and screw pitch error of the mean by the nc device march compensation, therefore, the numerical control machine tool positioning accuracy is higher.
