vertical milling center 500 ＆600 is deisgned with a vertical bed structure, the feed axis is X, Y, Z three coordinate control, the maximum rapid traverse speed is up to 20m/min; the main shaft is servo motor power drive, the power is 3.7Kw, the maximum speed is 8000rpm; The double-nut pre-pressed C3 ball screw is used, and the pre-stretching mechanism is adopted at both ends, which greatly eliminates the influence of thermal deformation on the precision of the CNC machining center. The positioning accuracy of the VMC machine is up to 0.008 mm. The vertical milling center is suitable for high-efficiency and high-precision automatic processing of small and medium-sized metal and non metal hardparts in aerospace, military and national defense, automobile and motorcycle, engineering machinery, refrigeration, and petrochemical, rolling stock and other industries.
