●12,000 min-1 spindle which is standard equipment, is directly driven and heat displacement is minimal because the motor and the spindle are heat insulated. ●X and Y axes realize smooth movement by the sliding surfaces of the rolling guide ways and Z axis sliding surfaces realize rigidity by sliding guide ways. ●The straightnes and perpendicularity are adjusted by scraping on the mounting surface of guide rail. So the precision can be maintained not only at initial term but also for a long term.
