Abstract

A grinding wheel is mounted coaxially of an internal diameter saw blade and rotates with the saw blade during operation. The grinding wheel includes a grinding disc and a center rod which is movably mounted within a central bore of the spindle of the slicing machine. Compressed fluid such as air is used to move the grinding wheel from a retracted position to an extended position against the bias of a spring secured to the center rod. The pressurized fluid is introduced into a chamber for moving an annular sleeve-like piston removably secured to the grinding disc. An adjustable stop ring is also mounted on an adaptor within the sleeve-like piston and has ears which can be deflected by screws from access openings in the grinding disc for fine running adjustments of the grinding disc. This stop ring can be accessed upon removal of the grinding disc from the center rod and sleeve-like piston in order to permit coarse initial adjustments in the positioning of the grinding disc.
