PROBLEM TO BE SOLVED: To realize machining of grooves having an ideal configuration by accurately adjusting grooves on a roller with grooves to a wire with fixed abrasive grain used in a wire saw without using a specific device for machining grooves.SOLUTION: Machining objects are a plurality of rollers 6, 7 with grooves which have been subjected to machining of V-grooves. The rollers 6, 7 with grooves are attached to a wire saw 1. A wire 10 with fixed abrasive grain is wound in a spiral at a low tension between the rollers 6, 7 with grooves along with a large number of V-grooves 8, 9 on each of the rollers 6, 7 with grooves. The rollers 6, 7 with grooves are rotated at different speed of rotation so that difference in speed occurs between the rotation speed of each of the rollers 6, 7 with grooves and traveling speed of the wire 10 with the fixed abrasive grain, resulting in formation of U-grooves 12, 13 on V-grooves 8, 9 due to grinding action by the wire 10 with the fixed abrasive grain. |
