これらの問題を少しでも護和させるためのものである。[Detailed Description of the Invention] This invention provides that a sander (grinder) is very conveniently used for lifting metal products such as iron plates and castings, but the metal noise generated at that time is It's so noisy that it's hard to put up with it, and there are cases where complaints are made about the noise that echoes from the workplace to the neighborhood, and we are forced to take countermeasures.
This is intended to alleviate these problems even a little.

である。The following is data on the reduction in noise. Compared to the high-pitched metallic sounds of the past, the sound is duller, so the psychological effect on workers and neighbors is abnormally large.

, 5-3, 5 When using a continuous sander with a low-noise grinding wheel, it is best to use a three-phase 200 volt power sander, as the motor of the sander experiences more resistance than conventional grinding wheels.

味As a result of the above, sander finishing workers are less bothered by noise, and the number of complaints from neighbors about noise has been drastically reduced or eliminated.
