The CNC grindstone shape multi-processing machine grindstone dust collecting and discharging device according to the present invention is a CNC grindstone shape consisting of discharging dust in a working space for machining a grindstone workpiece with a tool in a CNC grindstone shape multitasking machine In the grindstone dust collecting and discharging device for a multi-tasking machine, a dust discharge passage through the working space and the outside air is formed at a lower portion of the frame of the multi-tasking machine, and a suction fan for transmitting air and dust power is provided at the outlet side of the dust discharge passage. It is connected to the, dust collection port for collecting dust is made to be connected to the outlet side of the suction fan, and the dust discharge passage is divided into a plurality of suction in accordance with the direction of dust generation and dust scattering in the working space of the multi-task machine It is to adjust the position and the amount of suction. Therefore, in the present invention, since the dust generated when working with the shape of the grindstone is sucked and discharged from the work space to the outside along the dust discharge path, the stacking of dust in the work space is greatly reduced to reduce the inconvenience of cleaning dust frequently. It is possible to quickly discharge dust in the working space to the outside, thereby exerting an effect such that the operator can quickly perform the work of replacing the grindstone workpiece in the working space without delay.
