In this era of increasingly advanced technology, precision machining has become an indispensable mechanical equipment for people in industry, but how much do you know about the craftsmanship of precision machining? Let's go to find out with Xiaobian next.
One, face first, hole second
For parts such as box body, bracket and connecting rod, the plane should be processed first and then the hole should be processed. In this way, the holes can be positioned on the plane to ensure the accuracy of the plane and the orientation of the holes, and it is convenient for the processing of the holes on the plane.
2. Process the datum surface first
During the processing of parts, the appearance as the positioning reference should be processed first, so as to provide a precise reference for the subsequent processing as soon as possible. Called 'benchmark first.'
3. Finishing
The primary surface finishing processing (such as grinding, honing, fine grinding/rolling processing, etc.) should be carried out at the final stage of the process. The surface finish after processing is above Ra0.9um, and slight bumps will damage the surface. In Japan, Germany and other countries, after finishing processing, you must use flannel for maintenance. It is definitely forbidden to directly touch the workpiece with your hands or other objects to avoid damage to the surface of the finishing process due to the transfer and equipment between processes. .
Fourth, distinguish the processing stage
The appearance of high processing quality requirements is divided into processing stages, which can generally be divided into three stages: rough processing, semi-finishing and finishing. The first is to ensure the quality of the processing; to facilitate the rational use of equipment; to facilitate the organization of the heat treatment process; and to find the defects of the blank when it is convenient.
The above is the editor's basic introduction to the precision machining process. If you have any questions, please consult this site, website address: http://www.dghongye.com
