JET GH-1440ZX Large Spindle Bore Geared Head Lathe

The JET GH-1440ZX lathe combines heavy-duty construction, geared headstock performance, and increased spindle capacity for demanding industrial machining applications. Designed for professional machine shops, toolrooms, fabrication facilities, and maintenance departments, this 14″ x 40″ metal lathe provides the power and rigidity required for turning, facing, boring, drilling, threading, grooving, knurling, and parting operations.

Powered by a 5 HP three-phase motor, the GH-1440ZX delivers the cutting power needed for demanding turning applications. Its geared headstock provides 12 selectable spindle speeds ranging from 36 to 1,800 RPM, allowing operators to choose appropriate speeds for different workpiece materials, tooling, and machining requirements.

With a 14″ swing over the bed and 40″ distance between centers, this machine accommodates a wide variety of workpieces, including shafts, bushings, threaded components, and precision-machined industrial parts.

One of the machine’s standout features is its 2.55″ spindle bore, which allows larger-diameter bar stock to pass through the headstock. This increased spindle capacity can reduce the need for cutting stock into shorter lengths or repeatedly repositioning workpieces.

The JET GH-1440ZX lathe features a D1-6 camlock spindle mount, MT6 spindle taper, and MT4 tailstock taper for compatibility with appropriately sized workholding equipment and turning accessories.

Its one-piece cast iron base provides a rigid foundation designed to help minimize vibration and machine deflection during heavier cutting operations.
