Abstract

A cutting apparatus includes: a processing feeding unit that performs processing feeding of a chuck table adapted to hold a workpiece; and two cutting units in which rotational axes of two spindles coincide with each other and cutting blades mounted to the spindles face each other. Each cutting unit includes a flange mechanism in which the cutting blade having a cutting edge fixed to an outer peripheral edge of a one-side outer surface of a circular disk-shaped base is fixed to the spindle. The flange mechanism is fixed to a tip of the spindle, sucks an other-side outer surface of the base of the cutting blade, and fixes the cutting blade to the spindle with the one-side outer surface of the base exposed to the side of the tip of the spindle, and the one-side outer surfaces of the cutting blades fixed to the two cutting units.
