Abstract

PURPOSE:To apply a constant load on a coil spring and to press the end face of a coil spring to a grindstone with a constant force irrespective of the dispersion in the whole length of the coil spring by placing a weight in a specific weight on the upper end face of a coil spring to be polished held in a vertical state. CONSTITUTION:A deadweight 6 in a preset weight is placed on the apex end face of a coil spring 3 held in an erecting state. The end face of the coil spring 3 is thus subjected to polishing by press-fitting the lower end face of the coil spring 3 to a grindstone 4 under rotation with a constant load.

(Problem to be Solved by the Invention) However, generally there is variation in the overall length of the coil spring, so when the coil spring 3 is inserted between the top stopper 5 and the grinding wheel 4, the amount of contraction of the coil spring 3 is constant. However, there were problems such as the pressure force of the coil spring 3 against the rotating grindstone 4 was not constant, and the amount of polishing of the end surface became unstable. Therefore, the height position of the top surface stopper 5 must be adjusted each time according to the entire length of the coil spring 3, which poses problems such as an increase in the time required for machining.
