Abstract
A grinding wheel position detecting means for a surface grinding machine, in which a super-grain grinding wheel is composed of a base metal fastened to a longitudinal end portion of a rotating shaft and a super-grain layer provided on a longitudinal end face of said base metal, and a longitudinal end face of the super-grain layer is utilized as a grinding surface.
Claims6
In a surface grinding machine wherein a super-grain grinding wheel composed of a base metal fastened to a longitudinal end portion of a rotating shaft and a super-grain layer provided on a longitudinal end face of said base metal is utilized for a grinding surface;
- a grinding wheel position detecting means comprising:
- an annular groove formed in an outer peripheral surface of the base metal, said annular groove having a cross section partially defined by a pair of longitudinally spaced edges with at least one of said edges normal to the axis of rotation of said shaft, and a sensor for detecting a longitudinal position of the annular groove is located near said one edge of said groove and spaced radially outwardly from and facing said outer peripheral surface of said base metal, whereby the position of said grinding wheel is detected by sensing movement in the position of said one edge of the annular groove.
