the wider application of surface grinding machine grinding is one of the main methods of the precision machine parts processing. however, because of the high grinding wheel speed, grinding wheel and more hard, brittle, can not stand the heavier impact, accidental improper operation, through the grinding wheel can cause very serious consequences. therefore, the security technology of grinding work appears especially important, must adopt reliable safety protection device, operation to concentration, to ensure foolproof. in addition, the grinding wheel on the artifacts of splash out fine sand dust and metal scrap, hurt workers' eyes, if a large number of workers in this kind of dust is harmful to the body, also should take appropriate protective measures. when grinding, should pay attention to the following safety technical problems.
should be carefully before driving on checking up surface grinding machine, including the operating mechanism, electrical equipment and magnetic chuck checking fixture. after check again after the lubrication, lubrication test, confirm everything is good, just can use.
card artifacts when loading note cards, card, in the process of surface grinding machine grinding workpiece can cause artifacts fly loose serious consequences such as cuts or bump broken grinding wheel. began to work, application of manual control mode, the grinding wheel slowly near and artifacts, to start feeding, forbid to overexert, prevent collision grinding wheel. need to use iron control table reciprocating motion, grinding length according to the workpiece, accuray adjusted, will block iron tightly fastened.
replacing grinding wheel, must first appearance inspection, whether there is injury, with a wooden hammer or sticks to hit, demand of ringing is no crack. installing a grinding wheel assembly must be in accordance with the provisions, the methods and requirements, static balance after debugging for installation, commissioning, after everything is ok, just can use.
workers must wear protective glasses in a work, when dressing grinding wheel balancing to, prevent collision. measurement artifacts, adjust or wipe the machine tools will be made after the downtime. magnetic chuck, to disk, workpiece rub-up, tight, the fast absorption, can add block iron when necessary, to prevent the shift of the artifacts or fly out. attention should be paid to pack good grinding wheel cover or surface grinding machine backboard, positive stance to tilting high-speed rotating grinding wheel.
