Grinding processing of cylindrical internal grinding machine is widely used. To a certain extent, one of the main methods for precision machining of machine parts is that the grinding wheel is hard and brittle and can not withstand heavy weight. Impact, accidental mishandling, crushing the grinding wheel can 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.
The fine sand and metal scraps splashed on the workpiece of the grinding wheel during the grinding of the cylindrical grinder can 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.
In the cylindrical grinder, when the workpiece is loaded, the card should be stuck and clamped. The looseness of the workpiece during the grinding process will cause the workpiece to fly out of the injured 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. When replacing the grinding wheel, it is necessary to first check the appearance, whether there is any trauma, and then use a wooden hammer or a wooden stick to strike, and the sound is required to be clear and crack-free.
