ABSTRACT
Basic process of machining the chemical pipeline. 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 planar obvious basis to ensure the rough machining and machining precision machining hole, a good foundation on the bottom surface of the 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 is a combination of the selection tool. Special fixture fixture selection, a self-locking mechanism, therefore, higher production efficiency, for large quantities, to meet the design requirements.
