Technical Field

The invention relates to a part of a grinding machine, in particular to an anti-sticking disc mechanism of the grinding machine.

Background

In industrial production, particularly in ultra-precision machining, a grinding machine is high in machining precision and wide in machining material, and is widely applied to various industries. During the processing of the grinding machine, a proper amount of grinding fluid is added to increase the friction force during the processing of the grinding machine, so that the processing precision of the equipment is improved; in addition, the grinding fluid can take away heat and debris generated in work in the flowing process, so that the temperature and cleanliness in work are ensured, and the work efficiency and the quality of workpieces are improved. However, this also leads to an undesirable phenomenon: the upper disc of the grinder is in close contact with the workpiece during the processing, and after the processing of the grinder is finished, part of the processed part is adhered to the upper disc of the grinder and cannot fall off automatically due to the existence of atmospheric pressure. In actual production, the processing is generally performed manually, which is time-consuming, labor-consuming and low in efficiency, and also affects the processing quality of the processed parts, thereby affecting the good rate of the processed parts.
