CNC precision machining parts should be noted in the processing
In order to ensure precision CNC machining parts, CNC roughing and CNC finishing should be carried out separately, CNC roughing with large cutting volume, large workpiece cutting force, large clamping force, large thermal value, obvious cold hardening conditions on the machined surface, and large internal stress on the workpiece. If you continue to carry out rough machining on the workpiece, the accuracy of the finished parts may be lost quickly due to the stresses all over again. For some parts with high machining accuracy, low-temperature annealing or aging treatment should be arranged to remove the thermal stress after rough machining and before finishing.
CNC reasonable choice of precision mechanical parts processing - equipment.
CNC rough machining is mainly to remove most of the machining allowance precision CNC non-standard parts precision requirements are not high. Therefore, roughing should be carried out on high-power, low-precision machine tools, CNC precision hardware machining process must be high-precision machine tools. Roughing and finishing on different machine tools, not only can more effective use of the equipment's capabilities, but also can increase the application cycle of precision machine tools.
