Cutting apparatus

A cutting apparatus that cuts a workpiece by a cutting blade, the cutting apparatus comprising:

• a chuck table that holds a board in which a groove is formed through cutting of the board by the cutting blade;
• a cutting unit having a spindle and a mount flange that is fixed to a tip part of the spindle and on which the cutting blade is mounted;
• and
• a replacement apparatus that replaces the cutting blade mounted on the mount flange with a cutting blade stored in a blade storer and further replaces the board placed on the chuck table with a board stored in a board storer,
• wherein the replacement apparatus includes a holding part that holds one at a time, under suction from a vacuum source, the cutting blade that was stored in the blade storer and the board that was stored in the board storer,
• wherein the holding part has a board support part that includes a first surface that supports and holds, under suction, the board that was stored in the board storer,
• wherein the holding part further has each of a first groove and a second groove formed therein, the first groove and the second groove being separated from one another so as to be disposed at different depths with respect to the first surface,
• wherein the holding part further has a blade suction pad, the blade suction pad being seated within the second groove and being connected to the vacuum source,
• wherein the blade suction pad contacts and holds, under suction, the cutting blade that was stored in the blade storer,
• wherein the board support part is disposed circumferentially about the first groove, and
• the board held under suction is supported by the board support part in a state in which the board held under suction is not in contact with the blade suction pad.
