Abstract

A grinding machine for grinding endless saw chains (1) with left-hand and right-hand saw teeth comprises a feeding wheel (2) adapted to take up a saw chain (1) for feeding the teeth thereof to a grinding position, and a grinding wheel (10) which, in the grinding position, is engageable with a saw tooth for grinding the cutting edge thereof, characterised by a tensioning means (3) displaceable away from the feeding wheel (2) to engage the saw chain (1) and keep it tensioned on the feeding wheel both during feeding and during grinding; a first sensor (5) adjacent to the tensioning means (3) for sensing the displacement thereof and thus determining the length of the saw chain (1); a computer unit which is preprogrammed with information about the length, pitch, and number of saw teeth of standard saw chains, for determining the theoretical number of saw teeth of the saw chain (1) to be ground, the theoretical number serving to determine the total length of feed of the feeding wheel during grinding of the saw chain (1); and a second sensor (8) adjacent to the feeding wheel (2) for sensing the passing of the cutting edge of the cutting portion (12) of the saw teeth while the saw chain (1) is advanced by the feeding wheel (2), this sensing serving to control, by means of the computer unit, the feeding of the cutting edge of the saw tooth and the movement of the grinding wheel (10) to the grinding position.
