Abstract
For superfinishing an elongate cutting tool which has been rough-ground by a separate machine, a pair of grinding wheels are first urged against the opposite sides of the work via respective fluid-actuated cylinders, until sufficient fluid energy builds up in the cylinders to enable the grinding wheels to grind the work to any desired depths. Being mounted on a common carriage, the grinding wheels are then reciprocated longitudinally of the work while being held in constant rotation and being urged against the work under the fluid pressure. On reaching either end of the work during such reciprocation, the grinding wheels are relieved of the fluid pressure until they restart traveling toward the other end, in order to avoid overgrinding the opposite ends of the work. The reciprocation of the grinding wheels is terminated when the opposite sides of the work are ground to required degrees. The complete operation can be automated. Preferably, one of the grinding wheels is angularly displaceable relative to the work about an axis parallel to the longitudinal direction of the work.
