A method of grinding the edge of a disc uses a grinding machine having mounted thereon a grooved grinding wheel, in which the groove is formed in situ using a forming wheel also mounted on the grinding machine. After a workpiece has been ground or after a succession of workpieces have been ground, re-engaging the grinding wheel and the forming wheel with the grinding wheel remaining in situ, to re-form the groove in the grinding wheel to correct for wear. A grinding machine comprises a grinding wheel, drive means therefor, a workhead and workpiece spindle and drive means therefor, a forming wheel and drive means therefor, means for moving the grinding wheel so as to plunge grind the edge of the grinding wheel to form a groove therein of precise cross-section and means for effecting relative movement between the grinding wheel and the forming wheel to enable the grinding wheel to engage with the edge of a circular workpiece component mounted on the workpiece spindle to edge grind the component and wherein the forming wheel is also mounted on the workpiece spindle for rotation therewith, and the grinding wheel is a resin bonded wheel.
A grinding machine, comprising a grinding wheel and drive means therefor, a workhead and workpiece spindle and drive means therefor, a forming wheel and drive means therefor, means for moving the grinding wheel relative to the forming wheel so as to plunge grind the edge of the grinding wheel to form a groove therein of precise cross-section, means for effecting relative movement between the grinding wheel and the workpiece spindle to enable the grinding wheel to engage with the edge of the disc workpiece mounted on the workpiece spindle to edge grind the workpiece, wherein the forming wheel is also mounted on the workpiece spindle for rotation therewith.
An edge grinding machine comprising a rigid platform on which a workhead spindle and a grinding wheel spindle and a forming wheel are located, wherein the grinding wheel spindle is itself mounted on a sub-assembly which is mounted to permit movement thereof parallel to the direction of advance of the grinding wheel spindle to achieve edge grinding of a workpiece mounted on the workhead spindle, but so as to inhibit movement thereof in other directions, wherein the grinding wheel is formed with a groove around its workpiece engaging surface, the cross sectional shape of which is the complement of what is to be formed around the periphery of a workpiece by grinding when the wheel is engaged with the workpiece periphery, whereby relative movement between the grinding wheel and the forming wheel enables engagement of the grinding wheel and forming wheel without the grinding wheel being demounted from its spindle.
