Method for Ball Screw Generation without Form- Dressing

概要

論文の詳細を見る
This paper deals with the development of a method for ball screw generation. The method is based on a generation process that uses a standard-shaped grinding wheel, instead of a form-grinding process with a form-dressed grinding wheel, and requires no extensive form-dressing process. With the newly developed thread-generation system, the wheel axis is set three-dimensionally at the computed optimum angle of inclination, based on the tilt and swivel angle components of the planned ball screw and grinding wheel. The optimum angle of inclination that gives the minimum geometrical error is determined by a numerical simulation of the generation process with the aid of a computer. The suggested ball screw generation method is shown to be effective by computer simulations with several geometrical shapes of grinding wheels and generation experiments.
