ABSTRACT:
A dicing machine including a flange cover which covers the blade and is divided into two such that a first cover is openable. An interlock device is provided so that a blade attaching and detaching device cannot be attached when the first cover is at the closing position, the first cover cannot turn to the closing position when the blade attaching and detaching device is attached, and the processing of the work is not started when detected radiation of a blade breakage detector, attached to the first cover, is not reduced by a predetermined amount. Consequently, the blade and the work are prevented from being damaged by processing the work without applying coolant, the mechanism of the dicing machine and the blade attaching and detaching device are prevented from being damaged without detaching the blade attaching and detaching device, and the work is prevented from being being unprocessed.
