Chamfering is a professional term in mechanical automation, because to remove the burrs on the parts due to machining, and to facilitate the assembly of parts, chamfering is generally made on the top of the parts. You can see chamfers everywhere in your life, such as on the frame of mobile phones, tempered doors, vases, etc. In fact, there are also chamfers on precision machine tool bearings, so what are the functions of chamfers on precision machine tool bearings? We summarize as follows for everyone: 1. The bearing steel must have chamfers during the initial processing before the heat treatment process. In this way, the stress is released during the heat treatment process of the material, and the internal structure and structure are spread again, so that cracks are not easy to occur and deformation is reduced. All play a very important role. Chamfering can solve the problem of stress concentration. 2. The chamfering is ground and polished to make the equipment not sharp and not easy to scratch the user; 3. It plays the role of guiding and precise positioning during assembly. Generally, the outer chamfer of the precision machine tool bearing and the inner chamfer of the inner hole are circular arcs. In addition to effectively preventing contact pressure, the most important thing is to facilitate assembly. The arc can ensure a good transition fit. Especially in the bearing link, the matching shaft and the positioning surface of the hole shaft are actually a part of the shaft shoulder and the bearing seat shoulder. The chamfer size of this part directly affects whether the precision machine tool bearing can be properly assembled and timely. Only when the torque is accurate can the rotation be stable! (http://)
