Abstract: The method is for profiling blades with a belt grinding profiling machine. The blades are mounted into a vise. A vertical position of the template is adjusted by rotating the rotatable knob. The motor is turned on to rotate the grinding belt over the grinding wheel. The guide wheel engages the underside profile of the template. The guide wheel of the template guides movement of the grinding wheel mounted on the common axle by moving the guide wheel along the underside profile of the template. The grinding belt grinds material off the underside of the blade until a portion of the underside profile of the template is copied to the underside of the blade.

Abstract: The blade holder has a movable plate and a fixture. A rotatable bolt in operative engagement with a block attached to the plate. A motor is in operative engagement with the bolt. The motor rotates the bolt to move the plate towards the fixture to grip a first set of blades until a torque threshold value is reached. The processor determines a number of blades included in the set of blades based on the number of rotations of the bolt. A first grinding portion of a rotating abrasive belt is applied against the set of blades (having width (W1)) to sharpen the set of blades. Sliding a vise sideways a distance (W1) until a second grinding portion is aligned on top of the second set of blades.

Abstract: Computer-implemented method of operating an ice skate blade grinding apparatus, which comprises determining a number of contiguous ice skate blades inserted into the apparatus; and setting an operating parameter of the apparatus based at least in part on the determined number of contiguous ice skate blades. This allows optimized sharpening and profiling of multiple blades at a time.
