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.
Claims18
An ice skate profiling apparatus, the ice skate profiling apparatus comprising:
- a movable blade holder configured for holding one or more ice skate blades elongate in a longitudinal direction of the apparatus;
- a template holder coupled to the movable blade holder and spaced from the movable blade holder in a first transverse direction to the longitudinal direction of the apparatus, the template holder being configured to hold a template having a profiling surface comprising a profile to be copied onto at least a portion of an ice-contacting surface of the one or more ice skate blades;
- a first hub and a second hub mounted on a common axle and spaced from each other in the first transverse direction, the first hub being configured to be movable in a second transverse direction to the longitudinal direction of the apparatus to contact and follow at least a portion of the profiling surface of the template held in the template holder, the second hub being configured to move in conjunction with the first hub;
- and
- a motor-driven abrasive belt connected to the movable blade holder, the abrasive belt being configured to be rotatable about the second hub and to move in conjunction with the second hub to contact the ice-contacting surface of the one or more ice skate blades to apply the profile of the template to the one or more ice skate blades;
- wherein the blade holder is configured to be reciprocated along the longitudinal direction of the apparatus during a profiling operation of the one or more ice skate blades such that the one or more ice skate blades held therein translate relative to the rotating abrasive belt as the first hub follows the at least a portion of the profiling surface of the template, the rotating abrasive belt removing material from the at least a portion of an ice-contacting surface of the one or more ice skate blades to copy the profile of the template onto the at least a portion of an ice-contacting surface of the one or more ice skate blades.
