Characteristics of CNC Machine tools Part One
Feb 27, 2018

I. High flexibility

The surface accuracy of the workpiece mainly depends on the processing procedure, different from the ordinary machine tool, it does not need to manufacture or change many tools, fixture and also does not need to adjust the machine tool frequently. CNC Machine tools are suitable for the development of single piece, small batch production and new products, which shorten the production preparation cycle and save a large amount of cost of process equipment.


II.  High machining precision

The machining accuracy of CNC machine tools can generally reach 0.005-1mm. The CNC machine tools are controlled in the form of digital signals. Each pulse signal is output by the numerical control device, and then the moving part of the machine tool moves a pulse equivalent (generally 0.001mm). The average error between the reverse clearance of the feed chain and the screw pitch can be compensated by the numerical control device, therefore, the positioning accuracy of the CNC machine tool is relatively high.

III. Stable and reliable processing quality

Under the same machine tool, same machining conditions, same cutting tool and the same machining procedure, the cutting tool path of same batch of parts is exactly the same; the part consistency is good and the quality is stable.
