Body parts of the main plane of the surface and pore system. In general, the plane guarantee processing precision than that of holes machining precision easy. Therefore, this design follows the surface after the first hole principle. Plane with holes and the processing clearly divided into roughing and finishing stages of holes to ensure machining accuracy. Datum selection box input shaft and the output shaft of the supporting hole as a rough benchmark, with top with two holes as a precision technology reference. Main processes arrangements to support holes for positioning and processing the top plane, and then the top plane and the supporting hole location hole processing technology. In addition to the follow-up processes individual processes are made of the top plane and technological hole location hole and plane processing. Supported hole processing using the method of coordinate boring. The whole process of processing machine combinations were selected. Selection of special fixture fixture, clamping means more choice of pneumatic clamping, clamping reliable, institutions can not be locked, so the production efficiency is high, suitable for large batch, line processing, can meet the design requirements.
