The main processing surface steering lever parts of the plane and the holes. In general, the plane guarantee precision machining is easier than to guarantee the machining accuracy. Therefore, the design follows the surface after the first hole principle. And the hole and the plane processing clearly divided into roughing and finishing stages of processing to ensure accuracy. The main process is the first locating hole processing the top plane, and then the hole processing technology series top plane and the position of the hole. Process in addition to individual and the top plane positioning technology and other processing of the hole and the plane is in in the follow-up process. By using the coordinate boring hole. In general the whole process selection. Fixture fixture, clamping means more choice of pneumatic clamping, clamping reliable, agencies can not lock, therefore the production efficiency is high, suitable for large batch, line processing, can meet the design requirements.
