GRINDING WHEEL FOR GRINDING A WORKPIECE

摘要

A grinding wheel (11) is adapted to be mounted on a grinding apparatus for grinding a workpiece. The wheel comprises a plate (13) adapted for rotation about a rotation axis, a supply port extending through the plate for supplying a grinding fluid to the plate, and a plurality of spaced-apart grinding teeth (21a, 21b) on s surface of the plate for grinding the workpiece. The teeth are disposed radially outward from the supply port so that fluid impinges upon the teeth as the plate is rotated. Gaps between adjacent grinding teeth have a total length between 2% and 10% of a sum of the total length of the gaps and a total width of the teeth so as to reduce flow of the grinding fluid radially outwardly of the wheel between the teeth for use in maintaining adequate fluid between the grinding wheel and the workpiece in operation.
