However, it is difficult to fix the workpiece having various shapes, particularly, the metal workpiece having a thin film thickness in a form cutable from the CNC machine, There was a limit.

On the other hand, as a metal having a thin film thickness, a metal driver blade 5 (hereinafter referred to as a 'blade') constructed as shown in FIG. 1 has a blade body (not shown) extending in the longitudinal direction and forming a plurality of teeth 6 A blades 5b protruding from one end of the blade body 5a and a threaded portion 7 extending from the flange 8 opposite to the brake blade 5b The blade body 5a is formed with a concave groove 5c which is concaved inward, so that a cross section of a thin film thickness is formed.

A simple procedure for cutting such a metal blade is as follows. First, a grip portion is machined to the machined workpiece after cutting to a predetermined length, and then a screw portion is machined at one end. Then, the grip portion is placed on the jig, The workpiece is separated from the jig and fixed on the jig while converting the surface on which the grip part is formed into a cutting processable state, Cutting process.

However, in the related art, in the process of cutting the groove on the metal blade, the position of the grip capable of fixing the thin blade itself to the jig is basically not clear, so that it is difficult to fix the blade. There is a problem that the surface roughness is uneven and the workability is unstable because minute vibrations occur when a cutting tool having a thin film thickness is contacted with a cutting tool of a CNC machine.
