Title:
SEGMENT GRINDSTONE HEAD FOR VERTICAL-SHAFT SURFACE GRINDING MACHINE
Document Type and Number:
Japanese Patent JP2018047513
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a segment grindstone head for a vertical-shaft surface grinding machine in which circulation inhibitors for preventing the circulation of a grinding fluid supplied inside the segment grindstone are mounted in each gap between the adjacent segment grindstones, and thereby grinding powder generated in the grinding is washed away to prevent clogging of grindstones.SOLUTION: A segment grindstone head 2a for a vertical-shaft surface grinding machine includes multiple segment grindstones 3a and a grindstone holder 4a having an annular end 41a where the segment grindstones 3a are mounted. In the segment grindstone head 2a for the vertical-shaft surface grinding machine, respective segment grindstones 3a are mounted respectively while gaps 6a are provided between the adjacent segment grindstones 3a in the annular end 41a of the grindstone holder 4a, a feed port of the grinding fluid is provided inside the segment grindstones 3a in the grindstone holder 4a, and a workpiece with a ground surface wider than the bottom surface of the grindstone head 3a in a plan view of the grindstone head 3a is ground. Circulation inhibitors 7a for preventing the circulation of the grinding fluid are mounted in respective gaps 6a.SELECTED DRAWING: Figure 2
