A rising demand for high quality ultra-fine ceramic pow-ders makes fine grinding one of the most important operations in ceramic processing. Three types of mills are commonly used: ball, vibratory and attrition. This article addresses Attritors and their applications. The Attritor was conceived by Dr. Andrew Szegvari in the 1920s.

Ceramic has the characteristics of high hardness, high strength, brittleness, belongs to the difficult processing materials. Due to the large sintering shrinkage, it is impossible to ensure the accuracy of the sintered preform body, so the ceramic still needs to be reprocessed after sintering. There are mainly 6 methods of machining ceramics.
Ultrasonic machining (UM) of ceramics is the machining method using the action of a slurry containing abrasive particles flowing between the workpiece and a tool vibrating at an ultrasonic frequency. The vibration frequency is 19 ~ 25 kHz. The amplitude of vibration 0.0005 - 0.002" (13 – 50 μm). During the operation the tool is pressed to the workpiece at a constant load.

The grinding machine provides high accuracy and fine surface finish with minimum tolerances. The machining process is done by the abrasive action of the grinding wheel; the abrasives are embedded over the periphery of the rotating wheel. In Grinding machine grinding wheel is work as a cutting tool and responsible for all machining processes.
