Working principle and notice of grinding wheel
On the surface, the grinding wheel piece cutting workpiece is very simple, but it's working principle can not be simple, a lot of people simply think that the work principle of grinding wheel is friction generated high temperature will be part of the contact. In fact, is not such, the working principle of the grinding wheel is corundum (including white jade, Zong Gangyu and Ming Gangyu) at the time of friction, resulting in a corner, which will cut the hard metal material. The sparks are just a phenomenon that has produced a high angle, and many people mistakenly believe that the heat produced by friction is melted.
The spark that the grinding wheel produces at work is very large, so it is necessary to pay attention to being hot. General grinding wheel piece in the work should pay attention to the following matters:
1, can not be placed around flammable and explosive goods;
2, do not wear polyester clothing, polyester is a by-product of oil is flammable;
3, do not wear short sleeved, but should wear long trousers.
4, wear protective glasses.
Above is the working principle of the grinding wheel and the note, we hope to help.
