The main processing parts processing plane and holes. In general, ensure easy to guarantee precision machining holes than. Therefore, the design principle is first machined surface after machining hole surface. Periodic hole machining plane is obvious that rough machining and machining precision machining hole. Based on the basic input and output, the bottom surface asa good foundation process. The main flow arrangement is supported in the positioning hole of the first, and then the processing hole plane and the hole positioning technology support. The whole process bination of the selection tool. Special fixture fixture selection, a self-locking mechanism, therefore, higher productivity, for large quantities, to meet the design requirements.
