Abstract:
An apparatus for use with a band saw sharpener having: (1) a grinding head assembly including an arbor, a grinding wheel mounted on the arbor, and a motor rotatably driving the arbor; (2) a saw feed mechanism including a reciprocating feed finger, providing indexing of the saw through the sharpener; and, (3) a sharpener frame, comprising:a. a sub-frame attached to the sharpener frame, said sub-frame including a pair of parallel plates, and a pair of support members extending between said plates; b. an electro-mechanical, X-axis driver, having a driver frame attached at one end to one of said support members, and further having an X-axis reciprocating element attached to the saw feed mechanism; c. an electro-mechanical, Y-axis driver, having a driver frame attached at one end to the other of said support members, and further having a Y-axis reciprocating element attached to the grinding head assembly; d. computer means interconnected to said X and Y axis drivers, for selectively moving the feed finger forwardly and rearwardly through an X-axis, and selectively moving the grinding wheel downwardly and upwardly through a Y-axis, so that a plurality of successive teeth, each having a hook portion and a gullet portion of predetermined location and configuration, are ground into the saw by the grinding wheel.
