Jet GH-1640ZX 16” x 40” Large Spindle Bore Gear Head Lathe JT1-2712

Description

The JET GH-1640ZX is engineered for shops that require increased horsepower, larger through-spindle capacity, and greater rigidity without moving to a longer bed machine. With a powerful 10HP, 3-phase motor and a 3.15" spindle bore, this 16" x 40" gear head lathe is built to handle heavier stock, tougher materials, and higher material removal rates.

The D1-8 spindle nose supports industrial-grade workholding solutions, while 12 spindle speeds ranging from 26–1500 RPM provide the torque and flexibility required for aggressive turning, precision threading, deep boring, and production-facing operations.

Safety and uptime are standard — not optional. The GH-1640ZX includes an electronic chuck key holder, foot brake, chuck guard, full-length splash guard, lead screw cover, and is UL 987 Certified for electrical compliance.

Every unit undergoes JET’s documented 30-Point Inspection before shipment to verify accuracy, gear engagement, safety systems, and operational readiness.

Backed by JET’s industry-leading 2-year parts and labor warranty, the GH-1640ZX is ideal for fabrication shops, energy-sector suppliers, industrial maintenance teams, and precision machining operations upgrading legacy equipment.

Features

• The 10HP motor provides the torque needed for deeper passes, harder materials, and improved metal removal rates compared to lower horsepower machines
• Larger 3.15" Through-Spindle Capacity Accommodates larger diameter stock, reducing secondary operations and increasing shop efficiency
• Industrial D1-8 Spindle Nose Supports robust workholding setups for demanding fabrication and production environments
• Rigid Cast Iron Construction One-piece base minimizes flex and vibration, improving repeatability and surface finish during heavy-duty turning
• Certified Operator Protection UL 987 Certified with standard foot brake, chuck guard, electronic chuck key holder, and lead screw cover to reinforce safe operation
• Inspected, Tested, and Ready to Run JET’s 30-Point Pre-Shipment Inspection verifies spindle accuracy, safety systems, controls, and gear function before arrival
