Abstract
A saw chain grinding machine (10) is provided for sharpening a cutter link (56) of a saw chain (24). A grinding wheel (20) is swingable into position for grinding. A chain carriage (48) then brings the cutter link (56) into engagement with the grinding wheel (20). The chain carriage (48) has a base portion (12) mounted to the machine with the base portion having a pair of upwardly extending vertical supports (72, 74). A guide bar (76) spans the distance between them. The carriage housing (49) is mounted to the guide bar (76) by a plurality of rollers (78, 80, 82, 84, 86, 88, 90, 92, 94) which permit the housing to freely roll along the bar. Movement of the housing (49) is controlled by a control cable (98) that is operable to move the housing and thus the cutter link against the grinding wheel (20).
