[0002] The valve core is one of the important components of the valve. The surface smoothness of the valve core is an important factor in evaluating the quality of the valve core. In the production and processing of the valve core, more and more stringent requirements are put forward for the treatment of the surface smoothness of the valve core. In particular, burrs are easily generated on the raised edge of the valve core. If the burrs are not polished thoroughly, and burrs are left on the valve core, it will have an adverse effect on the operation of the valve body, which may not only cause sealing defects, but also increase the internal wear of the valve body and reduce the service life. Therefore, the peripheral side wall of the valve core needs to be ground during the production and processing of the valve core.

[0003] When the grinding machine processes the valve core, a large amount of metal dust will be dispersed. The dust not only pollutes the working environment, but also harms people's health when inhaled into the body. This needs to be improved.
