Abstract

A spindle for rotating a grinding wheel of a grinding apparatus for grinding a substrate on which a balancing mechanism is provided for balancing the grinding wheel. The balancing mechanism is disposed on a shaft portion of the spindle, adjacent to the grinding wheel. The balancing mechanism includes a flange which includes an internal cavity configured to receive balancing components movable within the internal cavity during rotation of the grinding wheel. The internal cavity is configured to be accessible to adjust one or more of the balancing components. The spindle may be self-balancing, adjustable and/or otherwise enhanced to improve use of the grinding apparatus, such as by enabling easy and convenient adjustment of balancing properties of the spindle to balance the grinding wheel so as to provide optimal grinding of the substrate, manufacturing and/or servicing (e.g., maintenance or repair) of the spindle.

Abstract

A grinding wheel device for a grinding apparatus to grind a substrate (e.g., a runner of a skate), in which the grinding wheel device comprises a wheel and a grinding belt around the wheel that enable enhanced grinding (e.g., sharpening and/or profiling) of the substrate, such as by enabling faster, greater, and/or otherwise better grinding of the substrate, while maintaining simplicity and ease of use.

Abstract

The method is for sharpening a blade. An automatic sharpening apparatus (200) is provided that has a holder (204). A blade (214) is placed into the holder (204). A grinding-wheel driving motor (233), in operative engagement with a wheel (234) on a spindle (232), rotates a grinding wheel (212a, 212b, 212c) via a belt (236). A grinding assembly motor (208) moves the grinding wheel (212a, 212b, 212c) in an x-direction towards the blade (214). A linear motor (210) moves the grinding wheel (212a, 212b, 212c) from a first position to a second position in a z-direction without moving the grinding-wheel driving motor (233). The rotating grinding wheel (212a, 212b, 212c) engaging the blade (214). The grinding wheel (212a, 212b, 212c) sharpens the blade (214).

Abstract

The method is for sharpening a blade. An automatic sharpening apparatus (100) is provided that has a housing (102) with an elongate opening (104) defined therein. A blade (106) is placed inside the elongate opening (104). The blade (106) is tightened between self-centered clamp holders (137, 138). The rotation of the grinding wheel (120) is turned on. The rotating grinding-wheel (120) engages an underside of the blade (106) and automatically moves along the blade (106) by following a contour (107) of the blade (106). While the grinding wheel (120) moves along the blade (106), a counter-weight (132) provides a counter-weight to the grinding wheel (120). The blade (106) is sharpened while the blade is stationary inside the elongate opening (104) of the housing (102).

Abstract

A method is for using a skate-grinding device. The method provides an automatic sharpening system (10) that has grip members (14, 16) and a grinding wheel (28). A blade (18) of a skate (20) is inserted into a groove (19). The system is turned on. A motor (44) rotates the grinding wheel (28) and automatically moves the grinding wheel (28) within the groove to grind the blade (18). An electronic unit (86) measures a time the system (10) is used. A user of the system (10) is charged for the time measured by the electronic unit (86).
