Abstract:

A cutting disk adapted to be mounted with a rotating shaft to form the cutting head of a cutting machine. The disk includes a plurality of plates each of generally oval shape which mount a diamond cutting element along a major radius thereof. Each disk includes a slot with an L-shaped support formed along a corner formed by a slot wall and the periphery of the disk. The generally rectangular shaped diamond cutting element is secured in the slot with first and second edges thereof exposed. The plurality of disks are arranged along the rotating shaft with the cavities forming a continuous helical groove about the cutting head. This arrangement provides that the diamond cutting elements are sequentially brought into contact with the work surface for only a short period and then separated therefrom, thereby allowing the diamond cutting elements to cool between engagements.
