Abstract: A cutting apparatus is capable of cutting a work-piece depending upon the quality of the work-piece. The cutting apparatus produces parallelism between a knife edge of a cutting blade and a mounting face of the work-piece. A support having the blade is provided to a column capable of controlling a tilting angle of the blade in a blade length direction. Cutting is executed by controlling vertical movement of the blade. A driving source is capable of controlling movement linearly. The driving source produces a parallel relationship between a surface of a table and a knife edge. Different supports are each unitized to include a driving source and the blade vertically moved by the driving source. The different supports can be mounted interchangeably and selectively on a column of a cutting apparatus.

Abstract: To provide a cutting apparatus capable of executing cutting or half cutting of a work-piece depending upon quality of the work-piece by producing parallelism between a knife edge of a cutting blade and a mounting face of the work-piece.

Abstract: A cutting blade includes a shank portion and a cutting portion having a predetermined length and opposed sides, and affixed to the shank portion. The cutting portion has a cutting edge portion having a predetermined length and opposed sides and a continuous portion which continuously extends from the cutting edge portion to the shank portion, so that blade thickness gradually increases in a direction towards the shank portion. The cutting portion further has at least one pair of opposed concave curved surfaces substantially symmetrical to each other with respect to a center line, each opposed concave surface axially extending in a direction substantially parallel to the length of the cutting edge portion and provided on at least one of the cutting edge portion and the continuous portion.
