Research and application of precision control technology for C axis of A/C double pendulum angel milling head

The numerical control machine tools of various precision supplement each other, through the C axis error separation of A/C double pendulum angle milling head accuracy, for causes of each item of abnormal accuracy of C axis, analysis error detection method and the precision of control item by item, will eventually improve the C axis precision by local into an overall improvement, effectively improve the C axis machining precision, avoid the accuracy of C axis deviation caused by the parts quality problems.
