We all know that no matter what work we are doing, we should do some preparatory work first, so as to ensure that our work can be carried out smoothly. Therefore, whether it is the preparatory work or to understand some common sense, these are very important. So let’s learn what we need to know before CNC processing?
CNC processing in Dongguan
- Datum first: that is to process the datum plane first. During the machining process of parts, the surface as the positioning datum should be processed first, so as to provide the precise datum for the subsequent processing as soon as possible.
- Distinguish the processing stage: precision CNC machining quality request high appearance, all distinguish the processing stage, generally can be divided into rough machining, semi finishing and finishing three stages. The first is to ensure the quality of processing; it is conducive to the scientific use of equipment; it is convenient to organize the heat treatment process; and it is convenient to find the defects of the blank.
- Face before hole: for parts such as box, bracket and connecting rod, the plane should be machined first and then the hole should be processed. In this way, the hole can be processed by plane positioning, which ensures the accuracy of plane and hole orientation, and brings convenience to the processing of holes on the plane.
- Finishing: the primary surface finishing, such as grinding, honing, finishing, rolling, etc., should be placed at the end of the process path. There are two parts in drawing up the general rules of fine CNC machining road and the drawing up of precision CNC machining procedure. The first is to draw up the process path of parts processing, and then determine the process scale of each process, the equipment and process equipment used, as well as the cutting standard, man hour quota, etc
