When the grinding disc is driven for mechanical processing, the driving box drives the grinding disc to rotate through the transmission device, and the exhaust hopper draws the iron filings and dust generated by the processing into the dust extraction pipe through the fan, and then introduces them into the iron filing separation mechanism for iron filing separation. In this process, the driving box drives the grinding disc to deflect on the support frame by driving the bite assembly, and the grinding disc is lifted or moved laterally by driving the adjustment mechanism, thereby realizing automatic adjustment of the orientation of the grinding disc, and the dust and iron filings generated during grinding are extracted by the iron filing separation mechanism, and are separated separately to facilitate subsequent secondary processing, thereby making the processing of the grinding machine device more environmentally friendly.

The existing design of the mechanical processing grinder is not perfect in terms of fixation, and it is impossible to conveniently position workpieces of different sizes, and the process of taking and fixing the workpiece is too cumbersome and time-consuming; 2. The existing design of the mechanical processing grinder is not perfect in terms of position adjustment, and it is impossible to accurately adjust the distance between the grinding wheel and the workpiece, thereby affecting the working efficiency of the grinding wheel.
