The side grinding problem in the day-to-day use of the grinder, we often can find some of the operator, regardless of the type of grinder, regardless of the type of wheel, casually on the side of the grinding wheel grinding, which is a serious breach of security operations the procedures illegal operation behavior. Do procedures with the circumferential surface of the face of the grinding wheel should not use the side of the grinding, radial strength of this wheel, small axial strength operator excessive force will cause the grinding wheel crushing, or wounding in the actual the use of the process should prohibit such behavior. The positive operational problems in the day-to-day use, operator habits facing the grinding wheel operation, can pull its weight in this direction, in fact, such an act should specifically prohibit behavior in the operation of the grinder. Follow the rules, use the grinder grinding the workpiece, the operator should stand on the side of the wheel, not in front of the wheel to operate, to avoid failure grinding wheel, grinding wheel flying out of flying out of wounding or grinding wheel broken. Force operating problems in the use of grinders, some operations, especially the younger the operator, faster and grinding speed, the force is too large excessive, this is an extremely unsafe operation behavior. Any wheel flat itself has a certain strength, to do so is likely to cause fragmentation of the grinding wheel,cutting wheel  and even flying out of wounding, also a should be prohibited behavior. Common operational problems in the actual day-to-day operations, this happens, some production tasks in time, grab the working hours, the two shared a grinder to operate simultaneously, which is a serious violation operational behavior, shall be strictly prohibited. When a grinder is not enough, you can add the grinder way to solve, and definitely not at the same time share a grinder.
