The common operation problems of the sharpening machine in use are: the large bevel angle adjustment of the sharpening machine and the small bevel adjustment are not correct. After the grinding wheel angle is adjusted, the guide rail plate is not locked, causing the grinding wheel to jump or the whole machine to vibrate during grinding. When starting to learn the grinding, the grinding wheel has too much feed, which is equivalent to shaking too much. The blade can't bear the pressure. The sharpening machine grinds out the blade deformation. The blade width is different. Because the friction is too big, the back of the blade will There are intervals of burnt knife marks. Seriously burn the motor.

The bearing behind the sharpener blade is not used, or the blade is not capped, the blade is also deformed. When grinding, the grinding wheel was not cleaned in time, no sparks emerged, and it was still forcibly ground. The surface of the grinding wheel was filled with dirt, so the friction increased and the blade burned the knife.

The sharpening machine has a longer grinding time, and there is no watering and cooling on the back of the blade, causing the knife to burn. When the grinding wheel and the blade are not loaded, the grinding starts. As a result, the surface of the grinding wheel is deformed and the blade is deformed. The grinding wheel nut and the blade nut are not tightened, and the grinding starts. As a result, the grinding wheel is damaged, the blade flies out and hurts. After the blade is finished, the blade is not wound at the plane, so the blade is not sharp after grinding, and the normal procedure is not followed. Switching machine, there will be injuries.

When the sharpener was first sharpened, the position of the large bevel and the small bevel was not marked, and the bevel did not coincide.
