GIDDINGS & LEWIS G60-T HORIZONTAL BORING MILL

Technical Description

The GIDDINGS & LEWIS G60-T HORIZONTAL BORING MILL is a robust machine designed for precision machining, originally manufactured in 1980 (Serial number: 450-61-80). It features a 6-inch spindle diameter with a #50 ANS taper, offering 48 inches of spindle travel (Z-axis) and supported by a 40 HP DC main spindle drive motor, capable of speeds ranging from 6 to 1,120 RPM (per AI data) or 1,500 RPM (per technical specifications). The machine is equipped with a large working envelope, including a 60 x 120 inch table with a substantial 60,000 lbs weight capacity, providing 120 inches of cross travel (X-axis). Vertical travel (Y-axis) ranges from 72 inches (Technical Specs) to 84 inches (AI Data). Control is managed by a Giddings & Lewis model 8000 CNC system installed in 1996, though some specifications suggest a Fanuc CNC control and new Fanuc drives. Tool handling is facilitated by a 60-position automatic tool changer (ATC), and features such as ball screws with servo drives, hi-speed traverse (300 IPM) for the Y-axis, in-process gauging with a probe, and a power draw bar enhance operational efficiency.
