Abstract

A grinding machine for cutters used in wood working machines such as superfinishing wood planing machines. The cutter grinding machine comprises a cutter rest, to which a cutter to be ground is attached, and grinding wheels being adapted so that either of them moves toward or away from the cutter; a proximate position-detecting means being provided for detecting a fixed proximity between the cutter and one of the grinding wheels; and a sequential-control means being provided so that the approximation between the cutter rest and the grinding wheel is temporarily stopped when the proximate position-detecting means has operated and then either the cutter rest or the grinding wheel is reciprocated in the direction for enabling the grinding wheel to grind the cutter. Even when the grinding wheels are worn down, each of them can be automatically brought to a fixed position proximate to the cutter at the beginning of grinding operation to ensure proper and efficient grinding operation at all times.
