PURPOSE: A round disc sander is provided to facilitate the rounding, a round milling, and surface grinding, and to set an angle between two sides at a time. CONSTITUTION: A round disc sander comprises a body(1), a dust collecting unit, a surface plate, a turning control unit, an angle adjusting unit(5), an encoder(6), a grinding unit, and a controller(8). A dust collection container is installed on the body. The dust collecting unit sucks the dust collected in the dust collection container. The turning control unit controls the surface plate by fastening or unfastening. The angle adjusting unit is inserted into the insertion groove(31) of the surface plate, and moves from side to side. The angle adjusting unit supports work pieces at a desired angle. The encoder outputs a signal about the rotary angle of the surface plate. A sandpaper(71) is attached to the front side of the grinding unit, and the grinding unit is operated by a motor(9). The controller controls the dust collecting unit and motor, and determines the signal from the encoder. |
