High Machining Accuracy Of CNC Machine Tools

The machining accuracy of CNC machine tools can generally reach 0.05-0.1mm. CNC machine tools are controlled in the form of digital signals. For each pulse signal output by the CNC device, the moving parts of the machine tool move one pulse equivalent (usually 0.001mm). Moreover, the reverse clearance of the machine tool feed transmission chain and the average error of the screw pitch can be compensated by the CNC device, so the positioning accuracy of CNC machine tools is relatively high.
