A blend of advanced chemistry and shape zirconia alumina abrasive with premium aluminum oxide grain for 23 times the life of aluminum oxide wheels, up to 20 percent increase in performance and life over our former zirconia alumina wheels.

A balled tip generally is used on pure tungsten and zirconiated electrodes and is suggested for use with the AC process on sine wave and conventional square wave GTAW machines. To ball the end of the tungsten properly, simply apply the AC amperage recommended for a given electrode diameter (see Figure 1 ), and a ball will form on the end of the electrode.

Zirconia prostheses require a grinding process in order to increase its adaptability or to adjust the occlusion during the fabrication or the clinical application,12,13 Silicone green stone has been frequently used for grinding and polishing of conventional ceramic or composite material; however, for grinding zirconia, it is recommended that dedicated zirconiaspecific grinding apparatuses and .

YSZ (Yttria Stabilized Zirconia) has the properties of high density, toughness and super hardness, which make it a good grinding media, enabling to achieve superior grinding efficiencies compared with other conventional grinding media such as Alumina and Agate.
