What is the positioning accuracy of vertical cnc milling

Positioning accuracy refers to the gap between the actual position of the part or tool and the standard position (theoretical position/ideal position) in mechanical manufacturing. The smaller the gap, the higher the accuracy. Positioning accuracy is a prerequisite for guaranteeing the machining accuracy of parts. The movement of the various moving parts of vertical cnc milling is completed under the control of the numerical control device. Each moving part can reach a certain degree of accuracy under the control of program instructions, and the accuracy it achieves directly reflects the accuracy that can be achieved by the processed parts. , The unit of accuracy is very small, usually micron as the unit.
