●Suitable for high-efficiency processing for injection screws, screws of extruders, large diameter/high-load ball screws. ●High speed heavy duty grinding is possible with ordinary grinding wheels such as, 1mm to 2mm depth of cut against non-hardened or tempered steel and 0.5mm to 1mm depth of cut against hardened steel and max. feed rate of 2400mm/min. ●With two-axis NC rotary dresser (optional), the wheel can be dressed and shaped to any shape. Because of the disk type diamond, the diamond is wear-free, groove shape can be easily maintained and man-power of the succeeding rubbing process can be reduced enormously. ●Equipped with the large capacity (2485 L) tank and 2000 L/min. processing separator device (optional), cutting dust generated by heavy grinding can be handled without fail. In addition, bed shape is fully worked-out, so the cutting dust does not accumulated on machine bed.
