How to protect precision ceramic parts?
2021 12/13
Ceramic grinding is widely used and is one of the main methods of precision machining of machine parts. However, due to the high speed of the grinding wheel of the grinder, the grinding wheel is relatively hard, brittle, and cannot withstand heavier impact. Occasionally improper operation can cause very serious Silicon Nitride Plate consequences if the grinding wheel is broken. Therefore, the safety technical work of the grinding process is particularly important. Reliable safety protection devices must be adopted, and the operation must be concentrated to ensure that it is foolproof. In addition, the fine sand and metal shavings splashed from the workpiece of the grinding wheel during grinding can hurt the eyes of workers. If workers inhale a large amount of this kind of dust, it is harmful to the body. Appropriate protective measures should also be taken. Attention should be paid to the following safety technical issues during grinding. The machine tool should be thoroughly inspected carefully before driving, including the inspection of the operating mechanism, electrical equipment, magnetic chuck and other fixtures. After inspection, lubricate and test run after lubrication to confirm that everything is in good condition before use. Pay attention to the clamping and clamping when loading the workpiece. The loosening of the workpiece during the grinding process will cause the workpiece to fly out and injure people or break the grinding wheel and other serious consequences. When starting to work, use the manual adjustment method to make the grinding wheel slower and approach the workpiece, and the starting feed should be small, and excessive force is not allowed to prevent collision with the grinding wheel. When Silicon Nitride Plate it is necessary to control the reciprocating movement of the worktable with the stopper, it must be accurately adjusted according to the grinding length of the workpiece to tighten the stopper. When replacing the grinding wheel, you must first perform a visual inspection to see if there is any trauma, and then strike it with a wooden hammer or stick. The sound is required to be crisp and free of cracks. When installing the grinding wheel, it must be assembled according to the specified methods and requirements. After the static balance debugging, the installation and the test run can be used after everything is normal. Workers should wear protective glasses during work, and dress the grinding Silicon Nitride Plate wheel in a balanced manner to prevent impact. Measure the workpiece, adjust or wipe the machine tool after stopping. When using a magnetic chuck, clean the disk surface and the workpiece, close it tightly, and suck it firmly. If necessary, add a stopper to prevent the workpiece from shifting or flying out. Be careful to install the protective cover of the grinding wheel or the baffle of the machine tool, and stand by the front of the high-speed rotating grinding wheel.
