Grinder safety protection
Jul 20, 2018

Grinding processing is widely used, and it is one of the main methods for precision machining of machine parts. However, due to the high rotational speed of the grinding wheel, the grinding wheel is relatively hard, brittle, can not withstand heavy impact, accidental improper operation, crushing the grinding wheel will have very serious consequences. Therefore, the safety technology work of grinding processing is particularly important. It is necessary to adopt reliable safety protection devices, and the operation should be concentrated and guaranteed to be foolproof. In addition, the fine sand and metal scraps splashed on the workpiece of the grinding wheel during grinding may damage the worker's eyes. If the worker inhales the dust in a large amount, it is harmful to the body and appropriate protective measures should be taken. Pay attention to the following safety technical issues when grinding.

The machine should be thoroughly inspected before driving, including inspection of the steering mechanism, electrical equipment and magnetic chucks. After the inspection, it is lubricated, and after lubrication, the test is carried out to confirm that everything is good before use.

When loading the workpiece, pay attention to the card being positive and tight. During the grinding process, the looseness of the workpiece will cause the workpiece to fly out of injury or crush the grinding wheel and other serious consequences. When starting work, apply the manual adjustment method to make the grinding wheel slower and closer to the workpiece. The starting feed rate should be small, and the force should not be too strong to prevent the grinding wheel from colliding. When it is necessary to use the iron stop to control the reciprocating motion of the worktable, it is necessary to accurately adjust the length of the workpiece according to the grinding length of the workpiece and tighten the retaining iron.
