Abstract

A sharpening machine for saws has a mount for a saw blade and a carrier which is adapted to be tilted about an axis of tilt oriented perpendicular to the plane of the saw blade. A support which is supported on the carrier is capable of swivelling relative to the carrier through at least 180.degree. about a swivel axis lying in the plane of the saw blade by a swivelling device and is capable of reciprocating along the swivel axis by a lifting device. A grinding head is supported on the support and carries a plate-shaped or cup-shaped grinding wheel and a grinding motor for driving the grinding wheel. The swivel axis in one operating position of the grinding wheel is contiguous with an active face of the grinding wheel. A second grinding wheel on the grinding head is arranged in offset relationship with respect to the first-mentioned grinding wheel. The grinding head is reciprocable relative to the support between the operating position of the first grinding wheel and a corresponding operating position or the second grinding wheel. The sharpening machine for saws according to the present invention reduces the setting-up time and idle periods of the machine in comparison to the machin…
