CNC Precision Machining

Principles for precision machining of this part is to rough, remove the excess material of the workpiece, processing should avoid heat denaturation when vibration occurs when excessive heat and tooling. Let machining spindle load is not too large, in order to ensure that no resonance machine and workpiece, the tool is not easy to passivation, decrease the amount of infeed and machining depth, increase or decrease the speed of the tool speed can be reduced resonance.

Replacement of the tool for the second semi-finishing, and the second processing is mainly carried out in order to ensure processing quality and workpiece above the hole, there is conducive to the rational use of equipment as well as easy to find quality problems like blank defect. The third process for finishing at a high speed in order to ensure that their products precision and smoothness, finishing the main surface of the workpiece, precision machining process route in the final stage, surface finish after processing more than in Ra0.8um slight collision will damage the surface after finishing, should be protected with velvet, absolute ban on hand or other objects in direct contact with the workpiece, so the surface of the workpiece, due to the transport and installation of inter-process and damage.
