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 size available in 6”. 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 24” 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
6 Bedways Construction
The cross slide and tailstock travels on separate bedways to redistribute cutting forces on to the machine body. There are 6 bedways, 1 V way and 5 flat ways. One additional bedway supports just the apron. This design also avoids inference between cross slide and tailstock during certain machining process.
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.
Powered Tailstock and quill
The standard tailstock is equipped with a motorized quill feed and motorized tailstock base travel. Large hand crank allows convenient positioning of tailstock quill. Hydraulic tailstock lock along the bed is optional.
