It's a driven grinding wheel machine MT3040 (with an oversized worktable) - Electric Grinding Wheel Machine

It is a grinding wheel machine that, in addition to meeting certain common requirements of grinding machinery, also features high rotational speed, simple structure, wide applicability, and is typically operated manually.

The working principle:

It is a driven grinding wheel machine that does not have its own drive system. During operation, it relies on an external power source to power its rotation. Typically, an electric motor is used to drive the grinding wheel via a belt, ensuring it rotates at the specified speed. Driven Grinding Wheel Machine.

It drives the grinding wheel and dust collector:

The driven abrasive wheel machine can also be connected with a dust collector for environmental dust removal. When the equipment is turned on, both the abrasive wheel machine and the dust collector start simultaneously. The dust particles generated during the workpiece grinding are drawn into the sedimentation chamber by the negative pressure of the fan. Large and heavy particles of dust fall directly into the ash drawer, while fine dust is carried by the air flow into the filter box. As it passes through the filter bags, the dust adheres to the dust on the filter core and falls into the ash discharge pan. The vibration time can be adjusted.
