Study on Estimation of Grinding Performance of Super Abrasive Wheels (1st Report)

Development of a Rapid Wheel Grade Testing Machine based on Ultrasonic Coring Method

Abstract

For an automatic grinding operation, it is necessary to establish a grinding performance database of super abrasive wheels. In this paper, a new rapid grade testing machine based on the ultrasonic coring method is developed in order to decrease the total cost and the period of grinding performance estimation of super abrasive wheels, and its validity is discussed. As the result, it is cleared that this method has good repeatability and is suitable for rapid testing of the grades of super abrasive wheels. Also, the stock removal rates in ultrasonic coring are dependent upon the specifications of abrasive wheels and their MOR values.
