Abstract
A sharpening machine for sharpening toothed saws comprises a support for a saw blade supporting the blade for rotary adjustment in a direction of feed. A carrier is mounted for rotation about a tilting axis. A lifting carriage is mounted on the carrier. A spindle head is mounted on the lifting carriage. A grinding wheel is rotatably mounted in the spindle head. The lifting carriage is mounted to the carrier for swiveling movement about a swiveling axis which intersects the axis of the spindle head. The lifting carriage is rotatable at least 180.degree. from a standard position in which the spindle head axis is located in or parallel to the plane of the saw blade. The tilting axis of the carrier is oriented perpendicular relative to a plane containing both the spindle head axis and the swiveling axis. The carrier is rotatable in a range of at least 90.degree. about the tilting axis. The tilting range lies on both sides of a neutral position in which the spindle head axis is disposed parallel to the direction of feed.
