Millstar VH-450 Horizontal / Vertical CNC Bed Mill
44" x 28" x 31"Travels
Millstar VH-450 CNC bed mill with horizontal and vertical spindles
  • The bed, column, saddle and table are manufactured from high quality Meehanite cast iron, stress relieved for high stability.
  • All slideways are hardened, precision ground, then coated with Turcite-B for maximum wear resistance.
  • The X, Y axes are protected by stainless steel telescopic covers.
  • The X, Y axis drive employs high precision lead screws, combined with double nuts, ensuring high accuracy of feed.
  • The spindle runs on precise angular contact bearings.
  • The spindle is precision manufactured from SCM21 alloy steel, heat treated and precision ground.
  • All gears in milling head are hardened and precision ground for quiet running.
  • The X-axis feed is driven by a high torque servo motor, providing variable feed speed.
  • The powerful spindle motor gives a high chip removal rate.
  • Choice of Fanuc, Anilam or Mitsubishi CNC controller.

Spindle Lubrication and cooling
The gears and bearings in the milling head are lubricated by an efficient lubrication system to ensure their normal service life. The oil, after fan cooling, is delivered to the gears and bearings. 		Telescopic steel slideway covers on Millstar CNC machining centre
Practical Telescopic Covers
The X,Y axes slideways are protected by telescopic cover to prevent scratching on surfaces from chips, and extend the service life of the machine. 		combination horizontal vertical milling headstock on Millstar cnc bed mill
Vertical and Horizontal Milling Head
A combination of vertical and horizontal spindles in a milling head for efficient machining.
When operating with a rotary table, 5 surface machining can be quickly accomplished.
The gears inside the milling head are manufactured from SCM-21, carburized and tempered, then precision ground for heavy duty machining and smooth urnning.
Automatic forced lubrication to the milling head gears ensures minimum gear wear and long service life.
