Hydrostatic RamHigh dynamic stiffness and damping allow heavy cuts

and produce better finishes with greater accuracy.

Headstock is a rigid and thermally-symmetrical one-piece casting.

Large 250 mm (9.8 in) square ram capable of 75 or 108 kW (100 or 135 hp) cuts and able to reach into 324 mm (12.8 in) minimum bore diameters.

Wear-free system uses preloaded hydrostatic pads. Hydrostaticdesign eliminates the need for gibs while maintaining alignmentsand accuracies.

Rapid traverse of 20 m/min (787 ipm).

Cross Slide Elevation and Clamping

The hydraulic actuation of the cross slide elevation

and clamping system is simple, safe and accurate.

Slip-stick free motion, without distortion, provides truer rail positioning.

Infinite number of cross slide positions. Adjustable cross slide accommodates parts of varying height whileminimizing ram extension.

Absolute linear feedback system provides immediate machinereferencing and eliminates need for limit switches.

Hydraulic cylinder elevation with secure mechanical clamping,1,000 kN (225,000 lb) per side.

Precision cross slide leveling with standard linearscale feedback.

Fast, High-Capacity Table BearingTable speeds to 500 rpm.

Combination angular and roller thrust bearing design minimizespart deflection and provides superior load carrying capacity.

Table runout of 0.005 mm (0.0002 in) TIR radially and axially produces precise, quality parts.

Plain tables and several chuck configurations available.

Two-speed transmission with 4:1 gear ratio.

Way System

Heavy-duty, size 65, linear roller bearing carriages ride onhardened and ground guideways. This rigid low-friction system supports high loads and fast 20 m/min (787 ipm)traverse speeds. Advantages of roller bearing systeminclude:

Lower friction results in higher positioning accuracy, bettercircular/contouring accuracy and low thermal growth forconsistent accuracy.

Low maintenance and ease of repair. Roller guides require lessoil, reducing coolant contamination. Less susceptible to damage,roller guides are also easy to replace.

4Accessibility and Optimized Cutting Performance

Large Swing Capacity and Ergonomic Access 2000 mm to 3700 mm (79.7 to 145.7 in)

maximum swing.

Wide operator access to parts.

All enclosures allow easy crane loading of parts.

Convenient tool loading and servicing with oolchangerinstalled at floor level.

Floor-level installation eliminates need for specialfoundations and facilitates machine relocation.

Full X-Axis Travel

Cut from both sides of center and probe diameters withfull X-axis travel left and right of center. Part processingtime is optimized with the capability of cutting from bothsides, since longer time is spent in the cut and fewer toolchanges are required.

Coolant Systems

The self-contained coolant system reduces maintenance,provides clean coolant to the tool tip and keeps the floordry. Optional performance series coolant system, well-suited for

live spindle operations, offers a 950 liter (250 gal) tank with40 bar (580 psi) coolant through-the-tool.

The high-performance coolant package optimizes chipevacuation. The package includes a flush coolant system andcoolant through-the-tool. The tank capacity is 1500 liters(396 gal). Coolant through-the-tool pressure is 70 bar (1015psi).

Convenient Tool Storage

A floor-mounted, 26-position tool storage disk is standard.

Several disk configurations are available with various combinations ofWedgeLock and modular tooling systems.

The storage disk also handles right angle heads, long boring bars andproprietary tools.

The floor-mounted system puts the height of the magazine at aconvenient level for tool loading/unloading and maintenance.

For additional tool storage, a chain-type magazine may be added.

WedgeLock System

The Giddings & Lewis WedgeLock System accepts standardindustry retention systems and modular tools reducing toolingcosts. Large gauge diameter provides optimal taper contact and permits use

of long tools - up to 700 mm (24 in).

Maximum tool diameter is 410 mm (16.4 in).

Maximum tool weight is 115 kg (52.2 lb).

150 kN (33,000 lb) clamping force.

Accepts 60 taper and standard modular tooling systems.

Coolant through-the-tool standard.

Versatile Live Spindle Option

Live spindles increase machining versatility. The optional rotatingspindle is capable of milling, drilling and tapping operations. Fits in WedgeLock Tooling System.

Superior live spindle bearing stiffness permits higher cutting forces.

Control Choices and Convenience Features

Right Angle Head

Improve cycle time and part quality with the livespindle right-angle head. Perform milling, drilling and tapping on the side of

the part without having to do a second setup. Byleaving the part fixtured and performing theoperations on the side, positioning remains true andpart quality is maximized.

Coolant through-the-spindle provides lubrication forimproved cutting performance and facilitates chipevacuation for drilling operations.

The right angle head is stored in the tool magazinefor quick and easy head changes.

Tooling for the right angle head may be stored in the6 or 12 position tool drawer or the extended 60 or100 position tool magazine.

4-Axis Version

The 4-axis model features two heads and tworams for simultaneous cutting of large diameterparts including bearings, disks and pulleys. Rough with one head and finish with the other.

Perform OD and ID cutting at the same time.

Two 26-position toolchangers are included, one foreach head.

C-Axis

Drill and mill turn a variety of features anywhereon a workpiece with the 360,000 position fullcontouring/positioning table. Dual pinions, underindependent servo control, are meshed with thetable ring gear providing a preloaded backlash-free joint.

8Options

Pallet Shuttle Adds Productivity

For higher volume jobs, pallet shuttle systems allow operatorsto setup additional parts while the machine is cutting. Equipped with one rotating load/unload station.

Available with one or two park stands.

Expanded Tool Magazine

For operations requiring more than 26 tools, a chain-type magazineis available increasing capacities to 68, 108 or 208 tools. Any tool

in the extended tool magazine may be used vertically orhorizontally in a right angle head.

Tool Probe

Tool probes increase machine utilization and provide precision from the first cut. Thetool probe corrects and modifies tool lengths. Tools can be qualified to 0.050 mm (0.002 in).

Part Probe

The part probe updates offsets and measures surfaces, diameters,lengths and angles to insure part quality. Probing on both sides ofcenter provides up to four times the probe accuracy compared toprobing the radius.

The probe is stored in the tool changer.

Enclosure Options

The standard enclosure measures 2,775 mm (109 in) from floor level. The optional full enclosurecovers the machines maximum cross slide travel.Both enclosures meet CE requirements.
