<p><P>PROBLEM TO BE SOLVED: To provide a bench cutter capable of easily cutting a processing member along a marking line by a cutting blade. <P>SOLUTION: The laser oscillator 201 of a bench circular saw 1 being the bench cutter is provided to the front 187A, which is turned to the front side of the bench circular saw 181, of a shaking support arm 187 and the upper surface of the processing member 1001 placed on the upper surface of a turntable 183 can be irradiated with a laser beam 201A. The laser beam 201A becomes a laser beam 201B to be projected on the processing member 1001. The position, where the laser beam 201A becomes the laser beam 201B to be projected, is set on a moving locus along which a circular saw blade 192 moves with respect to the processing member 1001 when the turntable 183 is revolved to allow the laser beam 201B to coincide with the marking line 1001A or in the vicinity of the moving locus. When the laser beam 201B is allowed to coincide with the marking line 1001A, fine adjustment is performed by a revolution fine adjusting part and a tilting fine adjusting part. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
