The surface grinder is widely used for grinding, which is one of the main methods for fine machining of machine parts. However, because the speed of the grinding wheel of the grinder is very high, and the grinding wheel is hard, brittle, and can not withstand heavy impact, accidental improper operation will cause very serious consequences. Therefore, the safety technical work of grinding is particularly important. We must adopt reliable safety protection equipment and concentrate on operation to ensure that there is no risk.

Fine sand chips and metal chips splashed from the workpiece of the grinding wheel during grinding will harm the eyes of workers. If workers inhale a large amount of this dust, it will be harmful to their health, and appropriate protective measures should also be taken.

Pay attention to the following safety technical problems when grinding Before starting, carefully check the surface grinder, including the operation organization, electrical equipment, magnetic chuck and other fixtures.

After checking, it shall be smoothed, and then the test run shall be carried out after being smoothed, and it can be used only after all are confirmed to be in good condition.

When clamping the workpiece, pay attention to the clamping. During the grinding process of the surface grinder, the workpiece will become loose, which will cause severe consequences such as flying out of the workpiece, hurting people or crushing the grinding wheel.

At the beginning of the work, use the manual adjustment method to make the grinding wheel slowly close to the workpiece. The starting feed should be small. Do not use too much force to avoid bumping the grinding wheel.

When it is necessary to control the reciprocating motion of the workbench with a block iron, it should be accurately adjusted according to the grinding length of the workpiece to tighten the block iron.
