Title: Cutting device for solid
Inventor: SUZUKI SHIGEHARU
IPC: B28D1/22
Filed: 1998-05-01
Abstract: PROBLEM TO BE SOLVED: To enable the smooth penetration of a polishing liquid, a cutting liquid or an abrasive grain and reduce an area where a blade comes into contact with a solid to be cut by rotating blades insetted, in a polygonal shape, into a circular frame. SOLUTION: Three pieces of blade 2 are combined into a triangular shape with a circular frame 1 or six pieces of blade 2 are combined into a hexagonal shape with the circular frame 1. The circular frame 1 is rotated as indicated by an arrow (b) and the three pieces of the blade 2 combined into the triangular shape are caused to rock forward/backward as indicated by an arrow (a) to achieve a cutting action. In addition, the pieces of the blade 2 are arranged at an interval 1 on the frame 1 and one piece of the blade 2 is caused to rotate helically in an opposite direction to the other piece 2 which rotates to cut a solid 4 to be cut. Thus the frequency of contact between the solid 4 and the blade 2 is increased to accelerate the cutting speed.  Consequently, it is possible to realize the extremely improved smoothness of penetration of a polishing liquid, a cutting liquid and an abrasive grain. Further, the combination of the blades 2 in a triangular or a polygonal shape contributes to the realization of miniaturizing the device. Also the saving of the contact area to the practically maximum possible extent enables the efficient cutting of the solid with thin blades.
