The grinding wheel is made of abrasive and binder, and the center of the circular fixed abrasive.
Side grinding problem:In the daily use of the sand turbine, we often find that there are many kinds of operators, regardless of the type of grinder wheel, the use of grinder wheel on the side of the grinding, which is a serious violation of the rules of safety operation.According to the rules of the grinder wheel which uses a circular surface to do the working surface.is not suitable for grinding, the radial strength of the grinder wheel, the axial strength is very small, the operator will cause the wheel to break, and even hurt, in the actual use of the process should be prohibited.
Positive operation problem:In daily use, many operators used is in front of the grinding wheel to operate. The reason is that the direction can be used with gusto, in fact, this kind of behavior is that grinder operation should be specifically prohibited behavior. According to operating procedures, the use of sand turbine grinding workpiece, the operator should stand on the side of the grinding wheel, not in the front of the wheel to operate, so as to avoid failure of the wheel, the grinding wheel flying out or grinding wheel broken.
Force operation problem:In the use of grinder, some operators, especially the young operator, for the sake of the grinding speed, force too much too fast, this is a very unsafe behavior. Any grinder wheel has a certain intensity, which is very likely to cause the grinding wheel is broken, and even fly out to hurt, but also a kind of behavior should be prohibited.
Common operation problem:
In the actual daily operation, there are such cases occur, there are people to catch  production tasks, grab the working time, two people share a sand turbine at the same time, this is a serious violation of the operation, should be strictly prohibited. When a turbine is not used, it can be used to solve the problem of adding a sand turbine.
