Jet GH-1440ZX 14” x 40” Large Spindle Bore Gear Head Lathe JT1-2711

Description

The JET GH-1440ZX is a 14" x 40" large spindle bore gear head lathe engineered for serious turning in fabrication, maintenance, energy, and industrial machining environments. Built with a rigid one-piece cast iron base, a powerful 5HP 3-phase motor, and a 2.55" spindle bore, this machine delivers the strength, control, and repeatability required for heavy cuts and consistent results.

Designed to reduce secondary operations and increase shop throughput, the GH-1440ZX allows larger stock to pass directly through the headstock, minimizing cutoffs and re-chucking. With 12 spindle speeds ranging from 36–1800 RPM, operators gain the flexibility needed for turning, facing, threading, boring, grooving, knurling, and parting operations across a wide range of materials.

Safety and uptime are built in — not added on. The GH-1440ZX is UL 987 Certified, includes a standard foot brake, chuck guard, lead screw cover, electronic chuck key holder, and is backed by JET’s industry-leading 2-year parts and labor warranty.

Every machine undergoes a documented 30-Point Inspection before shipment to ensure accuracy, safety validation, and operational readiness.

For shops upgrading legacy equipment or expanding turning capacity, the GH-1440ZX delivers the capability of a large bore lathe with the confidence of certified safety and national service support.

Features

• The 2.55" spindle bore allows larger diameter material to pass through the headstock, reducing secondary operations and improving workflow efficiency
• Rigid One-Piece Cast Iron Construction Heavy cast iron mass dampens vibration and limits flex under load, helping maintain dimensional accuracy during deep or aggressive cuts
• UL 987 Certification, electronic chuck key holder, chuck guard, foot brake, and lead screw cover come standard — protecting operators and facilities
• 5HP 3-phase motor and 12 spindle speeds (36–1800 RPM) provide torque and flexibility for threading, boring, facing, and production turning
• JET’s 30-Point Inspection confirms spindle accuracy, gear functionality, fluid levels, control systems, and safety validation before delivery
• Backed by a 2-year parts and labor warranty and nationwide service infrastructure to maximize uptime
