Features
Three Points Support Headstock Spindle
The headstock casting is designed with one ball bearing and two tapered roller bearings supporting the full length of the spindle shaft.
Spindle bore sizes are available in 6”, 9”’ 10″, 12” , and 15”. Double chucks are available as options.
Gears and shafts are made from hardened and ground alloy steel, the spindle is made from forged, chrome alloy material.
One Piece Casting Bed/Base
The oversized 32” wide bedways are induction hardened and ground for long lasting accuracy.
One piece casting bedways and base offer rigidity and stiffness to the entire machine to enhance heavy cutting
Center Mount Ball Screw
The ball screw that drives the carriage and cross slide is mounted between the bed ways in the center of the bed. Unlike the conventional design with the ball screw installed in front of the bed, this design disperse the driving force equally between the two sets of bedways and deliver a more positive force along the Z axis.
Large Selections Of Tool Posts
There are different types of optional turret tool posts to be mounted on the cross slide. There are 4 way, 6 way, 8, 12 positions hydraulic or motorized tool holding devices for different works.
