Rueda de amoladora de mano eficiente venta directamente a la venta aeroespacial

VP-300A is an automatic vibratory polisher designed to prepare high quality polished surfaces on a wide variety of materials, especially for electron-backscatter diffraction (EBSD) applications. The high frequency vibration in horizontal motion produces a very effective polishing action to remove minor deformation remaining after mechanical preparation and reveal the stress-free surface. Ideal for EBSD specimens preparation.

● Frequency and voltage controls. By adjusting the vibrating frequency, different size specimens can be polished. By changing the applied voltage, the speed of the polishing action can be easily controlled; 

● Timer control. Stop automatically;

● Capable of handling small or large specimens;

● Multiple size holders (1-inch up to 2-inch diameter, others can be customized);

● Robust and durable design;

● Easy to use and service;

● Ideal for all materials.
