What is the positioning accuracy of CNC machining center?

The positioning accuracy of the cnc machining center refers to the positional accuracy that can be achieved by the movement of the cnc machine axes under the control of the numerical control device. The positioning accuracy of the CNC machining center can be understood as the motion accuracy of the machine tool. Ordinary machine tools are manually fed. The positioning accuracy is mainly determined by the reading error. The movement of CNC machine tools is realized by digital program instructions. Therefore, the positioning accuracy is determined by the numerical control system and mechanical transmission errors. The movement of each moving part of the machine tool is completed under the control of the numerical control device. The precision that each moving part can achieve under the control of the program command directly reflects the precision that the machined part can achieve. Therefore, the positioning accuracy is an important test. content.
