In recent years, with the rapid development of China's precision machinery parts industry, people put forward high requirements for this industry. So, what are the general principles of automatic parts processing? Today, let's take a closer look at it.
1. Benchmark first. That is to say, the base level should be processed first. In the process of mechanical processing, the surface as the positioning base should be processed first, so as to provide the precise base for the subsequent process as soon as possible.
2. Differentiate the processing stages. Machining surfaces with high quality requirements can be divided into three stages: roughing, semi-finishing and finishing. The main purpose is to ensure the quality of processing, to facilitate the scientific use of equipment, to facilitate the arrangement of heat treatment processes, and to facilitate the discovery of wool in time. Defects of billet, etc.
3. Face before face. For box, bracket and connecting rod parts, the plane should be machined first and then the hole should be machined. In this way, the processing holes can be positioned in the plane to ensure the accuracy of the position of the plane and the hole, and to facilitate the processing of the holes in the plane.
4. Finishing. Primary surface finishing, such as grinding, honing, finishing and rolling, should be placed at the end of the process road. The formulation of the general criteria for the process path of fine parts processing and the formulation of the process rules for fine parts processing can be roughly divided into two parts. The first thing is to plan. Determine the process path of parts processing, and then determine the process scale of each process, equipment and process equipment, as well as cutting specifications, man-hour quotas and so on.
