Improves the sharpness of the grindstone. And by improving sharpness, grinding burn can be prevented appropriately and it can contribute to cost reduction. In addition, since truing is performed in an appropriate order and an appropriate route, truing can be performed in a shorter time, which contributes to shortening of processing time and energy saving. Further, it is possible to cope with processing of a crankshaft or the like of a special vehicle that requires the accuracy of the grindstone end face, thereby reducing the frictional resistance of the crankshaft and contributing to the improvement of the fuel consumption of the vehicle.
  • the truing method of the present invention can be variously changed, added and deleted without changing the gist of the present invention.
  • the configuration, structure, shape, and the like of the truing device of the present invention can be variously changed, added, and deleted without changing the gist of the present invention.
  • the configuration, structure, shape, and the like of the grinding machine 1 described in the present embodiment can be variously changed, added, and deleted without changing the gist of the present invention.

Abstract

L'invention concerne une méthode d'application de dressage, en utilisant un premier système de dressage et un deuxième système de dressage, à une surface périphérique extérieure d'une meule qui est parallèle à l'axe de rotation de la meule, et à une surface d'extrémité de la meule qui est orthogonale à l'axe de rotation de la meule, et à une surface d'arc de la meule qui est formée sur la partie limite entre la surface périphérique extérieure de la meule et la surface d'extrémité de la meule. Le premier système de dressage est utilisé pour dresser la surface périphérique extérieure de la meule et une surface d'arc côté périphérie extérieure, c'est-à-dire, une surface qui constitue une partie de la surface d'arc et qui continue vers la surface périphérique extérieure de la meule, dans un état dans lequel l'axe de rotation du premier système de dressage est maintenu parallèle à l'axe de rotation de la meule, et le deuxième système de dressage est utilisé pour dresser la surface d'extrémité de la meule et une surface d'arc côté surface d'extrémité, c'est-à-dire, la surface restante de la surface d'arc de la meule qui continue vers la surface d'extrémité de la meule, dans un état dans lequel l'axe de rotation du deuxième système de dressage est maintenu dans une direction orthogonale à l'axe de rotation de la meule.
