Positioning accuracy and repeatability

Positioning accuracy and repeatability of positioning accuracy, positioning accuracy is an exponential moving axis controlled machine tool that can be achieved in the end determine the actual position accuracy, the error is called positioning errors.  Diamond blade  errors include servo system, detection system, the error of the feed system, further comprising a moving member guide geometry errors. It will directly affect the precision machining parts. Repeatability refers to the CNC machine, and repeatedly run the same program code, the positional  cubic boron nitride  the resulting degree of consistency. Repeat positioning accuracy is affected by characteristics of the servo system, the feed gap transmission links and rigidity and friction characteristics and other factors. Under normal  abrasive grinding , repeat positioning accuracy is normally distributed error contingencies, it affects the number of parts machining consistency, accuracy is a very important indicator.
