Sharpening process for wood saw uses sharpening wheel with bend part corresponding to desired bend part of blade profile

摘要

Sharpening wheel (3) has convex part (1b-2b) corresponding to desired concave attack angle (1-2) of blade profile of wood saw. The convex profile is first cut in order to fit into the desired concave profile with particular device. Then the concave attack angle is obtained similar for each tooth by positioning the flat of sharpening tool (6) always at the same distance from the tooth's top. An Independent claim is also included for a device to cut the sharpening wheel profile.
