The grinding wheel has sharp abrasive grains and high hardness, which can grind hard and brittle materials such as cemented carbide, optical glass, ceramics, and alloys. The operator should stand on the side of the wheel when using the wheel. Do not operate on the front of the grinding disc, so as to avoid the grinding wheel flying out and hurting people. What other operations should be prohibited when using grinding discs?
1. Common operational issues.
In actual daily operations, this also happens. Some people are rushing production tasks and working hours. Two people share a grinder to operate at the same time. This is a serious illegal operation and should be strictly prohibited.
2. Force operation problem.
when using the grinder. Some operators, especially young ones, use too much force in order to grind faster. This is an extremely unsafe operation. Any grinding wheel itself has a certain strength. Doing so is likely to cause the grinding disc to break. Even flying out and hurting people is a prohibited behavior.
3. The problem of side grinding.
Grinding wheels that use the circumferential surface as the working surface according to the regulations should not use the side for grinding. The radial strength of this kind of grinding disc is large, and the axial strength is small. When the operator exerts too much force, the grinding wheel will be broken and even hurt.
After the grinding wheel has been working for a period of time, its working surface will be passivated. Continued use will increase the friction between the grinding wheel and the workpiece surface. Thus affecting the surface quality of the workpiece. Therefore, the appropriate time should be selected to dress the grinding disc in time.
When the customer is processing with a grinding disc. Be sure to check mainly on the grinding wheel. Once a problem is found, it should be solved in time.
