JET GH-1640ZX Large Spindle Bore Geared Head Lathe

The JET GH-1640ZX lathe combines heavy-duty industrial construction, high-horsepower performance, and increased spindle capacity for demanding metalworking applications. Designed for professional machine shops, toolrooms, fabrication facilities, and industrial maintenance departments, this 16″ x 40″ metal lathe provides the power and rigidity required for turning, facing, boring, drilling, threading, and general machining operations.

Powered by a 10 HP, 230V three-phase motor, the GH-1640ZX delivers the cutting power needed for machining larger workpieces and tougher materials. Its geared headstock provides 12 selectable spindle speeds ranging from 26 to 1,500 RPM, allowing operators to choose appropriate speeds for different workpiece materials, tooling, and cutting requirements.

With a 16″ swing over the bed and 40″ distance between centers, the machine accommodates a wide variety of industrial workpieces, including shafts, bushings, threaded components, and precision-machined replacement parts.

One of the GH-1640ZX’s standout features is its 3-1/8″ spindle bore, which allows larger-diameter bar stock to pass through the headstock. This increased through-spindle capacity is particularly useful for shops machining longer or larger-diameter stock.

The JET GH-1640ZX lathe features a D1-8 camlock spindle mount, MT6 spindle taper, and MT4 tailstock taper for compatibility with appropriately sized chucks, centers, and workholding accessories.

Its rigid one-piece cast iron base helps minimize vibration and deflection during heavier cutting operations, supporting machining accuracy and consistent surface finishes.
