Abstract

An ultrasonic impact process for impregnation of diamond powder on polishing and grinding wheels or discs is described. A slurry or paste of diamond dust and vegetable oil is passed across the top of the slowly rotating disc to be impregnated as shown in Fig. 1. The ultrasonic horn or driver is activated to vibrate in a vertical plane to the slurry.

Ultrasonic Impact Impregnation Technique for Diamond Polishing

An ultrasonic impact process for impregnation of diamond powder on polishing and grinding wheels or discs is described. A slurry or paste of diamond dust and vegetable oil is passed across the top of the slowly rotating disc to be impregnated as shown in Fig. 1. The ultrasonic horn or driver is activated to vibrate in a vertical plane to the slurry.

The vibration of the driver forces the diamond dust particles to pit and chip the surface of the disc, so as to form numerous cavities in the disc surface which are identical with the geometry of the particles. The high-impact forces associated with the ultrasonic impact process fill and anchor the particles in the numerous cavities and a near perfect semimechanical hold on the particles is achieved.

A comparison of the distribution, clamping and penetration characteristics affected by this process and previously proposed technologies is shown in Fig. 2.
