Development of Optically Controlled Automatic Balancer for Grinding Wheel

Abstract

This paper describes a non-contact type automatic wheel balancer which is operated by photo signals. It consists of driving mechanisms for balancing weights, actuators, power sources, control circuits and photo transistors. The photo transistors receive signals from the photo diodes which are set on a wheel cover. Thus, the rotating balancer can be operated under non-contact condition. Using this balancer, vibration amplitude on a wheel head of a surface grinder can be reduced to less than 0.05 μm in any cases.
