TOOL CHANGER:
Tools May be Pre-Selected and Held at "Ready" Position to Minimize Tool Change Time
The Tool Changer Mechanism Will Select Tools, Automatically Seeking the Shortest
Route (i.e. Fastest Time) Between Tool Locations in the Magazine

Standards Institute (ANSI) Standard for Tool Shanks for Machining Centers - ANSI
B5.50 - 1978

SPINDLE DRIVE - 75 HP (56 kw) MTDC:
Infinitely Variable Speed Thru Four (4) Gear Ranges
DC SCR Adjustable Voltage Drive with Reversible Spindle Rotation
Drip Proof Motor with Filtered Lower Ventilation
Electronic Overspeed and Field Loss Protection

HIGH SPEED HEADSTOCK:
The Hydraulically Counterbalanced Headstock Carries the Machine's Accuracy and
Exceptional Rigidity Right to the Workpiece
The Spindle is a Nitrided Steel Forging that Slides in Honed Tool Steel Bushings
Spindle and Sleeve Rotate in Preloaded Precision Timken Hydra-Rib Tapered Roller
Bearings with Automatically Adjusted Variable Preload
The Spindle is Driven by a Variable Speed DC Motor Through Hardened and Groun Helical Gears for a Virtually Direct Drive to the Spindle
There are No Hydraulic or Electric Clutches Used in Giddings & Lewis Horizontal Boring Machines
Spindle Speeds (Infinitely Variable): 9 to 2200 RPM
1st Range: 53 to 140 RPM
2nd Range: 134 to 353 RPM
3rd Range: 331 to 875 RPM
4th Range: 828 to 2200 RPM
HP Per RPM Up to Maximum Input HP: 1.5 (1.0 Kw)
Constant Torque Range: 9 to 53 RPM

SPINDLE SPEEDS:
Spindle Speeds are Infinitely Variable Within Each of the Four Ranges
Range Changes are Accomplished Through Integral Tooth Shifters
No Limitation on the Number of Spindle Reversals in Any Period of Time Means More Efficient Tapping

CLAMPING:
Servo Clamping Retains Position of Table, Headstock, Saddle, and Spindle. This Method is Unique in that it is "Self-Correcting"
The Servo Drive Motor is Locked in a Closed Loop Feedback System Which Prevents the Slide from Moving Off Position

POSITIONING PERFORMANCE WHEN NEW:
Per ANSI B5.54, Standard Data X, Y & W Axes, Unidirectional Absolute
Positioning Accuracy: .00018" / .0045 mm
Positioning Repeatability: .00009" / .0023 mm
Z Axis Accuracy: +.00100" / .0250 mm
Z Axis Repeatability: +.00024" / +.0060 mm

COLUMN:
Width Across 3 Ways on Column: 53" (1345 mm)
Cross Section of Each Way: 8" x 3.5" (203 x 88.9 mm)
Size of Body of Column Casting: 40.38" x 54" Deep (1025 x 1370 mm)

SADDLE:
Width Across Ways: 46" (1170 mm)
Cross Section of Each Way: 5.5" x 3.5" (140 x 63.5 mm)

BED:
Bed Width Across Ways: 52" (1320 mm)
Cross Section of Ways: 8" x 3.5" (203 x 89 mm)

LUBRI-COOL REFRIGERATION SYSTEM:
Refrigeration Oil is Circulated Through a Manifold Ring Around the Spindle
Bearings and Showered Throughout the Headstock
Thus, Spindle Drift is Minimized as the Oil Removes Heat from the Headstock and Returns it to the Lubri-Cool Unit Outside the Machine
