Static Accuracy of CNC Lathe

The static accuracy can only reflect the machining accuracy of the CNC lathe to a certain extent, because there are a series of factors that will affect the machining accuracy of the CNC lathe in the actual working state. For example, the elastic deformation of parts, thermal deformation, vibration of lathe, and the movement accuracy of moving parts of lathe at the speed of working state are different from the accuracy of low-speed detection, all of which will cause changes in the static accuracy of CNC lathe and affect the processing accuracy of workpiece. The working accuracy of CNC lathe is the accuracy under the action of motion and cutting force, that is, the accuracy of CNC lathe under the working state. The working accuracy is evaluated by the accuracy of the processed test piece. This accuracy is also a comprehensive indication of the geometric accuracy and positioning accuracy of the CNC lathe, which is reflected by the wire through the processing of parts.
