<P>PROBLEM TO BE SOLVED: To exchange a cutting blade without exchanging a blade mount to be fitted to a rotary shaft and a fixed flange. <P>SOLUTION: The cutting blade 1 is composed as follows. An annular blade 2 formed in an annular shape and an annular base 3 are integrated with each other via adhesive; an opening part is formed in a center of the annular base 3; an outer circumferential part 22 of the annular blade 2 is projected from an outer circumferential part 33 of the annular base 3; the inside diameter R1 of an inner circumferential part of the annular blade 2 is equivalent to or larger than the inside diameter R2 of the opening part. The cutting blade 1 can be directly fitted to the blade mount 5 to be used for fitting an electrocast hub blade to the rotary shaft 4, and the workability can be enhanced since the blade mount 5 and a fixed flange which has been previously used need not be exchanged. <P>COPYRIGHT: (C)2012,JPO&INPIT |
