Jet GH-2680ZH 26” x 80” Large Spindle Bore Gear Head Lathe with Newall NMS800 DRO JT1-3315

Description

The JET GH-2680ZH is engineered for large-diameter, high-mass turning applications where spindle capacity and horsepower are critical. With a commanding 26" swing, 80" between centers, and a massive 4.5" spindle bore, this machine is built to handle oversized shafts, heavy pipe, oilfield components, energy-sector hardware, and industrial rollers with confidence.

At the heart of the GH-2680ZH is a powerful 15HP, 3-phase motor, delivering the torque required for deep cuts in large-diameter material. The D1-11 spindle nose supports heavy-duty workholding systems designed for high-mass parts and industrial-grade clamping forces.

The one-piece cast iron base provides the mass and rigidity necessary to control vibration and maintain dimensional stability under extreme cutting loads. Twelve spindle speeds (10–1000 RPM) allow operators to balance torque and surface finish across heavy roughing and precision finishing operations.

The oversized 35" swing over gap expands clearance for large flange work and specialty applications, making this model a strong fit for fabrication shops, oil & gas suppliers, energy contractors, and industrial OEM facilities.

Standard safety systems include:

• Electronic chuck key holder
• Foot brake for rapid stopping
• Chuck guard at the point of operation
• Full-length splash guard
• Lead screw cover
• Integrated coolant system
• UL 987 Certification

Each GH-2680ZH is inspected prior to shipment and backed by a 2-year parts and labor warranty, delivering predictable ownership costs and long-term operational confidence.

For operations that routinely machine large pipe, heavy shafts, thick-wall tubing, and oversized cylindrical components, the GH-2680ZH delivers the spindle bore, horsepower, and rigidity required to do the job efficiently and safely.
