Safety guards for multi purpose grinding machines and a wide range of applications

Jun 05, 2019

Multi purpose grinding machines are widely used in grinding, and to a certain extent are 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.

When grinding a multi purpose grinding machines, the fine sand and metal scraps splashed on the workpiece of the grinding wheel may cause damage to 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 a workpiece with a multi purpose grinding machines, pay attention to the positive and tight clamping. If the workpiece is loose during the grinding process, the workpiece will fly out and hurt or crush the grinding wheel. 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.
