Some Problems Connected With Balancing of Grinding Wheels

Abstract

In most publications, the unanimous opinion prevails that an increase of grinding machine vibration as well as deterioration of workpiece quality are observed when the grinding wheel imbalance is on the increase. However, various data on the qualitative influence of wheel imbalance on the realization of the grinding process occur. In this paper a theoretical explanation of the influence of wheel imbalance on the dynamics of grinding, as well as the course and results of investigations proving theoretical considerations, are described. The widely known opinion is that only one-plane balancing of the grinding wheel is sufficient. Also the majority of wheel balancing equipment has the capability of only one-plane imbalance corrections. The purpose of the present paper is to prove that the wheels used in precision grinding always should be balanced in two planes.
