BLADE DRESSING MECHANISM, CUTTING APPARATUS PROVIDED WITH THE SAME, AND BLADE DRESSING METHOD USING BLADE DRESSING MECHANISM

摘要

PROBLEM TO BE SOLVED: To provide a dressing mechanism capable of realizing dressing of a workpiece cutting blade in a space-saving manner, a cutting apparatus having such a dressing mechanism, and a blade dressing method using the dressing mechanism.SOLUTION: A dresser 10 that dresses a workpiece cutting blade 3 is provided to be rotatable around a second axis L2 parallel to the first axis L1 of the blade 3. On the outer peripheral surface 11 of the dresser, a dressing area 12 slid into contact with the cutting part 3a of the blade when it is opposed to the outer peripheral surface of the blade and a relief area 13 set in a non-contact state with the cutting part are provided in a circumferential direction. A state is switched between a dressing state by the dressing area and a non-dressing state by the relief area by rotating the dresser around the axis L2.SELECTED DRAWING: Figure 5
