Grinding disk for hand held motor-driven grinding machine, has air inflow openings arranged to dust suction openings such that cross-flow of air inflow openings are formed to dust suction openings at grinding disk-lower surface

摘要

The grinding disk (5) has a central area (6) fastened at the grinding machine and a rotary motion is carried out in fastened state during operation. Multiple air inflow openings (21) are arranged at the grinding disk-lower surface (12) outside the center grinding disk area. Multiple air inflow openings are connected over an inflow channel that runs separately in the grinding disk by a suction channel. The air inflow openings are arranged to dust suction openings (16,17) such that a cross-flow of air inflow openings are formed to the dust suction openings at the grinding disk-lower surface. An independent claim is included for a grinding blade fastened at the lower surface of the grinding disk.
