[0002]

2. Description of the Related Art Generally, VTRs and Ds as information recording media are used.
AT magnetic tape or computer floppy disk is made of polyethylene terephthalate (PE).
T) or other plastic film on a Ni-based alloy or Co
A base alloy or the like is attached as a thin film by, for example, an evaporation method using an electron beam. In this case, a Ni-based alloy or Co
The base alloy is used as a material in the form of a plate or rod,
Alternatively, it is used as a material in the form of pellets.

[0003] As a method of manufacturing this rod-shaped material, conventionally, in order to prevent contamination of impurities, melting and scouring are performed in a vacuum, and a refractory is cast as an ingot in an ingot case lined on the surface. It is known that a predetermined final product shape is obtained by performing primary processing (rough processing) such as lumped forging and secondary processing (finish processing) such as finish forging and rolling. Subsequently, an oxide film is removed from the rolled product by polishing or the like to obtain a rod-shaped material.

A polishing method (centerless method) is adopted.

[0005]

By the way, in the above-mentioned prior art, the material to be worked is not particularly stable in shape with a rod-shaped material after hot working, and the outer peripheral surface is further rotated while rotating the rod-shaped material. Since the polishing is performed, there is a problem that the rod-shaped material may run out during polishing and the outer peripheral surface cannot be polished well. This problem becomes more remarkable as the outer diameter or length of the rod-shaped material increases, and there has been a strong demand for reduction of the run-out (safety) from the viewpoint of safety.
