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 has vertical rapid traverse

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 quiet running.

automatic lubrication system 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.

	Horizontal Spindle * Geared drive. The gears are hardened and precision ground. * 9 spindle speeds. * 5 HP spindle motor. * Spindle taper #40
	Rigid vertical head - driven by horizontal spindle. * The gears are hardened and precision ground on the gear drive milling head. * 9 spindle speeds. * 5 HP spindle motor. ( horizontal spindle motor ) * Milling head tilts 90° right and left. * Spindle taper #40
	Servo motor drive for two axes * The X and Y axes are driven by an AC servo motor, providing feeds and rapid traverse speed up to 2500 mm / min. ( 100 IPM )
	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.
	Power elevation of knee The knee elevation is driven by an individual motor for convenient operation. The knee also has rapid traverse function.
