What are the general principles of precision parts processing ？

　　1、 Baseline ahead

　　 I.e. machining datum first , Parts in Machining In process ， The surface used as positioning reference should be processed first ， In order to provide a precise reference for the processing of subsequent processes as soon as possible 。

　　2、 Division of processing stages

　　 Machining High quality appearance ， All Division of processing stages ， Generally, it can be divided into rough machining 、 Three stages of semi finishing and finishing 。 Mainly to ensure the processing quality ； Conducive to scientific application of equipment ； Easy to arrange heat treatment process ； And easy to find blank defects 。

　　3、 First face and back hole

　　 For case 、 Parts such as bracket and connecting rod shall be machined with plane first and then with hole 。 In this way, the machining hole can be positioned in a plane ， Ensure the position accuracy of plane and hole ， It is also convenient for the machining of holes on the plane 。

　　4、 Finishing machining

　　 Main appearance Finishing machining ， As abrasive 、 Honing 、 Fine grinding 、 Rolling processing, etc ， Should be placed at the end of the route 。 Draw up Precision parts processing General principles of process route , Precision parts processing Formulation of process procedures ， It can be divided into two parts 。 The first is to draw up the processing route of parts ， Then determine the size of each process 、 Equipment and process equipment used and cutting specifications 、 Working hours quota, etc 。
