CUTTING APARATUS

摘要

Disclosed herein is a cutting apparatus including a moving unit for moving a spindle to position a cutting blade, a rotary dressing mechanism for rotating a dressing grindstone on a rotational shaft parallel to the spindle, and an optical sensor for detecting the position of the outer periphery of the dressing grindstone. The cutting blade is positioned with respect to the rotary dressing mechanism depending on the position, detected by the optical sensor, of the outer periphery of the dressing grindstone, and the cutting blade is dressed by cutting into the dressing grindstone by a predetermined cutting distance.
