Title:
ワーク研削方法
Document Type and Number:
Japanese Patent JP6870569
Kind Code:
B2
Abstract:
To provide a work-piece grinding method that can grind a number of work-pieces.SOLUTION: In the work-piece grinding method in which a composite grindstone 1 is used which has a first screw-shape grindstone 2 for roughly grinding a gear-shape work-piece 4 with a plurality of teeth in grinding regions L1 and a second screw-shape grindstone 3 for finish-grinding the work-piece 4 ground in the grinding regions L1 in grinding regions L2 connected to each other in the same rotation shaft 11, it is set so that grinding regions L1 adjacent to each other partially overlap with each other when roughly grinding the work-piece 4 using the first screw-shape grindstone 2, it is set so that grinding regions L2 adjacent to each other partially overlap with each other when finish-grinding the work-piece 4 using the second screw-shape grindstone 3, and it is set so that a distance between grinding-start positions of the grinding regions L2 adjacent to each other is smaller than a distance between grinding-start positions of the grinding regions L1 adjacent to each other.SELECTED DRAWING: Figure 3
