Working requirements and main processing methods of hydraulic internal bore grinding machines

May 10, 2019

The machining of hydraulic internal bore grinding machines is widely used, and it is one of the main methods for precision machining of machine parts during operation. 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.

The fine sand and metal scraps splashed on the workpiece of the grinding wheel during the grinding of the hydraulic internal bore grinding machines will hurt 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 the hydraulic internal bore grinding machines is loaded with the workpiece, it is necessary to pay attention to the positive and tight clamping. 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. 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. When installing the grinding wheel, it must be assembled according to the specified methods and requirements. After static balance adjustment, install it, test the car, and use it after everything is normal. Workers should wear protective goggles at work and balance the grinding wheel to prevent impact. Measuring the workpiece, adjusting or wiping the machine must be done after the shutdown.
