Geometric accuracies are guaranteed only if machine is installed on foundation meeting the
minimum requirements of the machine and local building codes.

CONSTRUCTION:

BED, COLUMN, AND SADDLE
The bed is a rigid one-piece casting with heavy ribbing to prevent deformation during heavy cutting.
Fine grain Meehanite cast iron is used for its excellent dampening characteristics. The table is
fully supported by the saddle in all positions. There is no table overhang. The rigid box type column
casting is heavily ribbed to prevent twisting or distortion.

SPINDLE, HEADSTOCK, AND COLUMN
The high speed 12,000 RPM, 40 taper spindle is a true cartridge type unit supported by precision class
bearings that are permanently grease lubricated. The spindle is driven by a high torque 20 HP A.C.
motor. Power is transferred through a heavy-duty cogged drive belt eliminating slippage, promoting
thermal stability, and minimizing vibration.

BALANCED 12,000 RPM SPINDLE with spindle oil cooler 6000 BTU for High-Speed Machining

HARDENED AND GROUND C3 DOUBLE NUT BALL SCREWS are Pretensioned to minimize backlash, provide high precision
movement, and reduce heat deformation on all axes.

OIL JACKET SPINDLE CHILLER
Machine accuracy is maintained by using a refrigeration system that circulates cooled oil around the spindle
reducing the thermal effects of any heat generated.

AUTOMATIC TOOL CHANGER
The high quality 20-position tool changer uses a fast, random bi-directional twin arm with 2.5 second tool-to-
tool change time, and 7 seconds chip to chip.

BALLSCREWS AND AXIS DRIVES
Each axis is driven by a high precision double-nut ball screw. The ball screws are centered between the
guideways. The ball screws are supported on both ends by angular contact thrust bearings. This double
anchored pretension design provides outstanding positioning repeatability with virtually no thermal growth.
All axes have large diameter ball screws that are connected directly to oversize AC servo drive motors
without gears or belts, to eliminate backlash. Each axis has a flexible coupling to protect the ball screw in
the event of a sudden impact. These couplings can be quickly reset.

CONSTRUCTION (Continued):

PORTABLE MANUAL PULSE GENERATOR
The hand held “Manual Pulse Generator” lets each axis move in increments of 0.0001”, 0.0010” or 0.0100”
making fixture or part alignment quick and easy. The 10-foot cord gives full access to the machine.

PROGRAM AND DATA PROTECTION KEY SWITCH
The keyed switch enables the protection mode for both the program and offset data. Removing the key
limits access to only authorized personnel. In the unprotected position the key cannot be removed and all
data is available for edit.

FULLY ENCLOSED GUARDING
The fully enclosed guarding is made of heavy gauge sheet metal to contain both chips and coolant. The
large dual sliding doors open to provide unrestricted overhead access for ease of lifting heavy fixtures or
work pieces.

CHIP DISPOSAL AND COOLANT SYSTEM
High volume coolant system washes chips down into the front of sheet metal enclosure for chip auger
evacuation and provides flood coolant through adjustable head mounted nozzles along with four flushing
nozzles mounted directly to spindle nose.
