Abstract
A new centerless grinding method without regulating wheel is proposed. Instead of using a regulating wheel, this method employs an ultrasonic vibrating shoe to support the workpiece. The end of the vibrating shoe is in elliptic motion at a high frequency, while the rotational speed of the workpiece is controlled by the elliptic motion of the shoe. An experimental apparatus has been designed and constructed. Tests involving the rotational driving of a workpiece were then conducted on the apparatus, which showed that the workpiece rotational speed depended on the AC voltage and its frequency. Finally, grinding tests involving pin-shaped workpieces with an initial roundness of 20m were performed. The results showed that the roundness of the workpieces was improved to 1.5m after grinding using the new apparatus.
