Abstract
A circular saw blade sharpening apparatus using a rotating grinder wheel has a base frame which includes an arcuate, planar adjusting table. An elongated positioning arm has one end rotatably connected to the adjusting table so that it rotates around a saw tip alignment axis located at the center point of the arc of the adjusting table. The other end of the arm rotates over the adjusting table. A saw holding fixture is mounted to move along the positioning arm and permits a saw blade to be mounted so that its tips will intersect the saw tip alignment axis. The grinder wheel is mounted for rotation around an axis parallel to the adjusting table. It can also be moved into and out of engagement with the saw tips to be sharpened.
