Cutting machine

Abstract

A cutting machine comprising a chuck means for holding a workpiece to be cut and a cutting means for cutting the workpiece held on the chuck means. The cutting machine further has a first moving means for moving the chuck means relative to the cutting means in the first direction, a second moving means for moving the cutting means relative to the chuck means in the second direction perpendicular to the first direction, and a third moving means for moving the cutting means relative to the chuck means in the third direction perpendicular to the first direction and the second direction. The cutting means comprises a rotary blade which can turn on the center axis of rotation extending in the second direction and is shaped like an annular thin plate perpendicular to the second direction. The cutting depth of the workpiece is defined by the position of the circular periphery of the rotary blade in the third direction and cutting is carried out by moving the chuck means relative to the cutting means in the first direction. The cutting machine further comprises a rotary blade detection means capable of detecting the position of the rotary blade in the second direction and the position of the circular periphery of the rotary blade in the third direction.
