PURPOSE:To operate centerless grinding properly under high-precision roundness, increase blade grinding precision and improve operational efficiency. CONSTITUTION:A pair of semi-cylindrical blades 1 are fitted together and supported by means of positioning pin 10 of fitting jig 9 and thus form block 8 to be ground. Centerless grinding is operated on this block 8. Since deviation of inner blades 1 and deformation of block 8 are prevented by linking unit 3, high-precision centerless grinding can be performed. Further, blocks of inner blades 1 can be easily formed by only linking reinforcement plate 4 with linking hole 7 by means of positioning pin 10 of fitting jig 9 and turning prevention lock pins 11. |
