The machine adopts the method of double-sided grinding at the same time, which effectively improves the processing efficiency and workpiece quality. Its working principle is to apply uniform pressure to the workpiece placed in it through the precision-controlled upper and lower grinding discs, and with the appropriate grinding fluid, to achieve high-speed and precise surface grinding. Double-sided grinders are widely used in semiconductors, optical glass, ceramics, cemented carbide and other fields. They can meet a variety of processing needs from rough grinding to fine grinding, ensuring that the surface of the workpiece reaches the flatness and finish of the micron or even nanometer level.
