Abstract
A sharpener frame is supported relative to a floor and has a front side. A first portion of a band saw is supported at the front side of the frame. A second portion of the band saw is also supported relative to the frame, parallel with the first portion of the band saw, and also at the front side of the frame in one of two locations. Each location is on a different side of the first supported portion of the band saw. A clamp for the band saw tooth being sharpened includes a pair of plates having upper edges generally conforming to the profile of a saw tooth for clamping a substantial portion of the tooth in a fixed position relative to the frame during sharpening. The plates are released after sharpening for positioning a different tooth between the plates. A coolant supply system moves a liquid coolant through channels in the plates that have outlets adjacent to the tooth edge for cooling the tooth during sharpening. A grinding wheel is moved along the tooth upper edge following a predetermined path representative of the tooth profile for grinding the edge of the supported tooth while the tooth is held in the fixed position.
