Talk About Safety Technical Work And Safety Operating Procedures Of Grinding Machining Parts

The Grinding Machining is widely used and is one of the main methods of precision machining of machine parts. However, due to the high rotational speed of the grinding wheel of the grinding machine, the grinding wheel is relatively hard, brittle, and cannot withstand heavy impacts. Accidental improper operation and crushing of the grinding wheel will cause very serious consequences. Therefore, the safety and technical work of CNC Grinding processing is particularly important. Reliable safety protection devices must be adopted, and the operation must be concentrated to ensure safety.

In addition, the fine sand and metal chips splashed from the workpiece of the grinding wheel during grinding will hurt the eyes of the workers. If the workers inhale a large amount of this dust, it will be harmful to the body, and appropriate protective measures should also be taken. The following safety technical issues should be paid attention to when grinding machining. Before starting the machine, a comprehensive inspection of the machine tool should be carried out, including the inspection of the operating mechanism, electrical equipment, and magnetic chucks and other fixtures. After inspection, it is lubricated and after lubricating, a test run is carried out to confirm that everything is in good condition before it can be used.

When loading the workpiece, pay attention to the clamping and clamping. The workpiece loosening during the grinding process will cause serious consequences such as the workpiece flying out and hurting people or breaking the grinding wheel. When starting to work, the manual adjustment method should be used to make the grinding wheel approach the workpiece slower, the initial feed should be small, and excessive force should not be used to prevent the grinding wheel from colliding. When it is necessary to use the stopper to control the reciprocating motion of the worktable, it should be adjusted accurately according to the grinding length of the workpiece, and the stopper should be firmly tightened.

When replacing the grinding wheel, you must first check the appearance to see if there is any trauma, and then use a wooden hammer or wooden stick to strike, and the sound is required to be clear and no cracks. When installing the grinding wheel, it must be assembled according to the prescribed methods and requirements. After static balance debugging, the installation and test run are carried out. After everything is normal, it can be used. Workers should wear protective glasses during work, and should be balanced when dressing the grinding wheel to prevent impact. Measuring workpieces, adjusting or wiping the machine should be done after a shutdown. When using a magnetic chuck, clean the surface of the disk and the workpiece, hold it tightly, and suck it firmly. If necessary, add a stopper to prevent the workpiece from shifting or flying out. Pay attention to installing the grinding wheel protective cover or machine baffle, and the station should be over the front of the high-speed rotating grinding wheel.

9. After the work is finished, the grinding wheel must be shaken to a safe position, and each handle shall be adjusted to the normal position to clean the machine tool and the environment.
