Pace Technologies Vibratory Polisher

Pace Tech

The GIGA-1200 vibratory polisher has a solid, easy-to-use, robust design, and utilizes a 12-inch polishing bowl. The main benefits provided by the GIGA1200 are its ability to adjust both the vibration frequency and voltage. Adjusting the vibrating frequency compensates for the weight of the specimens, being polished; thus, small, or large samples can be prepared separately or simultaneously. In addition, the speed of the polishing action can be easily controlled by changing the applied voltage. Especially useful for EBSD polishing sample preparation (electron backscatter diffraction). Polishing is accomplished by setting the default frequency so that the sample begins to vibrate and then changing the voltage in order to adjust the rotational speed of the machine.
