Portable cutter machine for concrete components

摘要

The machine has a motor, a driven cutter disc, and a safety cover above two sides of the disc, to form a dust ejection passage with it. A blower fastened to the cover sucks in dust, which is generated during cutting, and removes the dust through the passage. A barrier wall on the cover forms on obstacle in the dust passage. A main dust suction aperture, and an additional suction aperture in the dust passage, are positioned in front of and behind the barrier wall respectively, in the rotation direction of the cutter disc.
