Abstract
An automatic blade changing system of a dicing machine uses a blade which is fixed to an auxiliary stopper member provided with a thread which is engaged with a thread of a spindle. The automatic blade changing system consists of two blade holding means which hold the blade to which the stopper member is fixed and rotate the blade relatively to the spindle in the state wherein the blade is forced to the spindle, a blade accommodating means which accommodates a blade to replace the blade, a moving means for moving the blade holding means between the end of the spindle and the blade accommodating means.

An automatic blade changing system of a dicing machine which rotates a blade fixed to a spindle shaft at high speed to groove a workpiece, said automatic blade changing system which automatically replaces said blade, comprising:
- two blade attachment and detachment means for holding said blade to which an auxiliary stopper member is fixed, said auxiliary stopper member being provided with a thread engaged with a thread of said spindle shaft, said blade attachment and detachment means rotating said blade relatively to said spindle shaft in the state wherein said blade is forced to said spindle shaft;
- blade accommodating means for accommodating a blade to replace said blade;
- moving means for moving each of said blade attachment and detachment means between the end of said spindle shaft and said blade accommodating means;
- and
- wherein one of said blade attachment and detachment means holds the blade to be attached, and the other of said blade attachment and detachment means holds the detached blade.
