The parts used in the industries have number of features. They are very powerful and retain their shape. They also are very powerful and act as shock absorbers as well. They are safe from point of view electricity as well because they are bad conductors of electricity. They are better compared to the metal parts as there is no rusting. Moreover, they are hard and lightweight at the same time. They have wide range of uses such as artificial medical devices, body armor etc. These are used in electronic devices as well which makes it widely used. There are many machining which use the ceramics. They are used in ultrasonic machining, laser machining etc.
Comparative to other categories, the most common is the ceramic grinding. This is done when it is in solid and sintered form. The technique is much cost effective as well. The ultrasonic process is used for drilling. The process is not very accurate but combine the ceramic grinding and machining processes.
