Side grinding problems in daily use of the grinder, we can often find the operator wheel machine types, regardless of wheel type, feel free to use the side of the grinding wheel for grinding, which is a serious violation of safety rules violation of operating behavior. Statute with a circumferential surface work surface side of the grinding wheel should not be used for grinding, the greater radial strength of grinding wheels, axial strength is small, the operator force too much will result in wheel breakage, even hurt, in practical use should be prohibited in such behavior. Positive operational problems in everyday use, many operators used to operate directly at the wheel because this direction with nothing, in fact, this behavior is behavior that should be specifically prohibited in the grinder operation. According to the rules, when using a grinding wheel machine, the operator should stand on the side of the wheel may not be operating on the front wheel so that wheel failure, fly wheel or wheel broken fly out wounded people. Operational issues when used in grinding machines, some operators, especially the younger operators, for the sake of grinding speed, hard than hard, this is a very unsafe behavior. Pingshen any grinding wheel has a certain strength, doing so may result in wheel breakage, even fly out the injured people is a prohibited act. Common operational problems in the actual daily operation, this is also the case, someone working for production tasks, take time, the two men shared a grinder while operating, and this is a serious violation of behavior, shall be strictly prohibited. A grinding machine is not enough time, you can add grinder solutions, absolutely do not allow simultaneous sharing of a grinding machine.
