Closed Loop Control Of Precision CNC Lathe

It is a direct linear or rotary detection device at the corresponding position of the final moving part of the machine tool, and the directly measured displacement or angular displacement value is fed back to the comparator of the numerical control device for comparison with the input command displacement, and the difference is used to control the movement Parts, make the moving parts move strictly according to the actual required displacement. The machining accuracy is generally about 0.002-0.01mm accuracy.
