60" Giddings & Lewis (G&L) Power Rotary Table – 30,000 Lb Capacity – Hydrostatic Lift

60" Giddings & Lewis (G&L) Heavy-Duty Power Rotary Table

Manufacturer: Giddings & Lewis

Table Diameter: 60" (Circular Platen)

Estimated Capacity: 30,000 Lbs.

Overview

This Giddings & Lewis 60-inch Power Rotary Table is an industrial-grade workholding solution designed for large-scale machining operations on Horizontal Boring Mills (HBM) and floor-type milling machines. Known for their extreme rigidity and "overbuilt" cast-iron construction, G&L tables provide the precision necessary for heavy boring, tapping, and multi-side machining of massive workpieces.

Key Performance Features

• Hydrostatic/Air-Lift System: Equipped with a lift system that reduces friction during rotation, allowing for smooth, effortless positioning even when loaded to maximum capacity.
• Precision Indexing: Features a 360-degree graduated scale (typically in 1/2-degree increments) and 90-degree positive-stop shot pins for repeatable, high-accuracy alignment.
• Power Bi-Directional Rotation: Driven by a robust electric motor and gearbox assembly, allowing for both clockwise and counter-clockwise rotation under power.
• Heavy-Duty Clamping: Features multi-point air/hydraulic clamping to the base, ensuring the table remains rock-solid during heavy interrupted cuts or high-torque boring.
