Grinder Safety Protection
Oct 18, 2022 View: 828 Leave a message

Grinding is widely used and is one of the main methods for precision machining of machine parts. However, due to the high speed of the grinding wheel of the grinder, the grinding wheel is hard, brittle, and can not withstand heavy impact. Occasional improper operation will cause very serious consequences if the grinding wheel is broken. Therefore, the safety technical work of grinding is particularly important. Reliable safety protection devices must be adopted, and the operation must be concentrated to ensure that there is no risk. In addition, the fine sand chips and metal chips splashed from the workpiece of the grinding wheel during grinding will harm the workers' eyes. If workers inhale a large amount of this dust, it will be harmful to their health, and appropriate protective measures should also be taken. The following safety technical problems should be paid attention to during grinding. Before starting, the machine tool shall be carefully inspected, including the inspection of the operating mechanism, electrical equipment, magnetic chuck and other fixtures. After inspection, lubricate it. After lubrication, conduct test run and confirm that everything is in good condition before use. Attention shall be paid to clamping when clamping the workpiece. Loose workpiece during grinding will cause serious consequences such as flying out of the workpiece, hurting people or crushing the grinding wheel. When starting to work, use manual adjustment to make the grinding wheel slowly close to the workpiece. The starting feed should be small, and excessive force is not allowed to prevent the grinding wheel from colliding. When it is necessary to control the reciprocating motion of the workbench with a stopper, it shall be accurately adjusted according to the grinding length of the workpiece, and the stopper shall be firmly fastened. When replacing the grinding wheel, the appearance must be checked first to see if there is any damage, and then the grinding wheel shall be knocked with a wooden hammer or stick. The sound shall be clear and clear without cracks. When installing the grinding wheel, it must be assembled according to the specified methods and requirements. After the static balance commissioning, it shall be installed and tested. It can only be used after everything is normal. Workers shall wear safety glasses during work, and the grinding wheel shall be trimmed in a balanced manner to prevent impact. Measure the workpiece, adjust or wipe the machine tool after shutdown. When using the magnetic chuck, the disk surface and the workpiece shall be wiped, tightened and firmly sucked. If necessary, a stopper can be added to prevent the workpiece from shifting or flying out. Attention shall be paid to installing the protective cover of the grinding wheel or the baffle of the machine tool, and the side of the station shall rotate the front of the grinding wheel at high speed.
