Powerful vertical head
  • The gears are hardened and precision ground on the gear drive milling head.
  • 9 spindle speeds.
  • 5 HP spindle motor.
  • Milling head tilts 90˘X  right and left.
  • Spindle taper NST#40
Power elevation of knee
  • The knee elevation is driven by an individual motor for convenient operation. The knee also has rapid traverse function.
Servo motor drive for two axes
  • The X and Y axes are driven by an AC servo motor, providing fast motion. Rapid traverse speed up to 2500 mm/min.
Precision ball screws on X and Y axes
  • The X and Y axes are transmitted by precision ball screws, combined with preloaded double nuts for extremely smooth and high precision working, with minimum backlash.
Features
  • The machine column is manufactured from high quality cast iron FC-30, tempered for long term accuracy.
  • FC-30 cast iron table is tempered, hardened and precision ground.
  • The spindle is precision machined from SCM-21 alloy steel. tempered and carbon treated, ensuring maximum stability for heavy duty cutting.
  • X and Y axes are driven by an AC servo motor for smooth traverse.
  • X and Y axis slideways are precision ground, and coated with Turcite-B wear resistant media.
  • The knee is power elevated and has rapid traverse function.
  • X and Y axes employ precision ball screws.
  • The drive gears in the powerful vertical head are hardened and precision ground for maximum wear resistant and low noise running.
  • Equipment with an automatic lubricator for lubrication to 3-axis slideways, feed screws, gears and bearings, ensuring high working efficiency and long service of parts.
  • The coolant tray effectively prevents cutting fluid leakage.
  • Employs high pressure coolant pump for efficient chip removing.
  • Halogen work fight.
