MILLING METHOD FOR ROTARY BLADE OF BRISK

摘要

PROBLEM TO BE SOLVED: To provide a milling method for rotary blades of a brisk wherein an amount of rotary blade imbalance is minimized. SOLUTION: The brisk 30 comprises a plurality of rotary blades 32 integrally arranged and formed at the outer peripheral part of a rotor 31. Out of the numbers except factors of the number of the rotary blades 32 of the brisk 30, an arbitrary number is set which has no common factor with the number of the rotary blades 32 excepting the number adjacent to the number of the rotary blades 32. The blades separated by the set number are sequentially milled. The amount of the imbalance among the rotary blades is reduced thereby. COPYRIGHT: (C)2004,JPO
