Abstract
A processing apparatus includes a holding table for holding a workpiece, a cutting unit including a spindle and a mount, a blade changer unit for mounting a cutting blade on or dismounting a cutting blade from the mount, and a control unit. The blade changer unit includes a blade chuck for holding the cutting blade and a moving unit. The cutting unit includes a vibration detecting sensor. The control unit includes a calculator for calculating the central axis of the mount from a position where the vibration detecting sensor detects vibrations caused upon contact between the mount and the blade chuck, and a mounting/dismounting controller for aligning the central axis of the blade chuck with the central axis of the mount and mounting the cutting blade on and dismounting cutting blade from the mount.
Claims10
A processing apparatus comprising:
- a holding table for holding a workpiece thereon, the holding table being processing-feedable in an X-axis direction relatively to a spindle;
- a cutting unit including the spindle and a mount fixed to a distal end of the spindle and having a boss extending in a Y-axis direction perpendicular to the X-axis direction;
- a blade changer unit for mounting a cutting blade on the boss of the mount and dismounting a cutting blade from the boss of the mount;
- and
- a controller for controlling the cutting unit and the blade changer unit, wherein
- the mount further includes a bearing flange for supporting the cutting blade, the bearing flange projecting radially from an axial rear end of the boss,
- the blade changer unit includes
- a holder for holding the cutting blade, and
- a moving unit for moving the holder,
- one or both of the cutting unit and the blade changer unit have a vibration detecting sensor for detecting vibrations, and
- the controller includes
- a calculator for moving the boss or the bearing flange and the holder relatively to each other in the X-axis direction and a Z-axis direction perpendicular to the X-axis direction and the Y-axis direction to bring the boss or the bearing flange and the holder into contact with each other at at least three contact points, and calculating a center of the mount from an X coordinate and a Z coordinate where the vibration detecting sensor detects vibrations caused upon the contact between the boss or the bearing flange and the holder, and
- a mounting/dismounting controller for aligning a center of the holder with the center of the mount calculated by the calculator and mounting the cutting blade on the boss or dismounting the cutting blade from the boss.
