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.
Claims9
An ice skate blade sharpening apparatus, comprising:
- a blade holder configured to grip a set of one or more ice skate blades placed therein;
- an abrasive belt having a width, the abrasive belt providing a first grinding portion spanning a first portion of the width of the abrasive belt and a second grinding portion spanning a second portion of the width of the abrasive belt;
- the blade holder being mounted with respect to the abrasive belt so as to be laterally shiftable in a direction of the width of the belt by aid of an actuator;
- a processor configured for:
- causing the first grinding portion of the abrasive belt to be applied against the set of one or more ice skate blades to sharpen the one or more ice skate blades;
- and
- controlling the actuator so as to laterally shift the blade holder a distance of at least the first portion of the width of the abrasive belt, to prepare for sharpening of a second set of one or more ice skate blades with the second grinding portion of the abrasive belt.
