JET GH-2180ZX Heavy-Duty Large Spindle Bore Geared Head Lathe

The JET GH-2180ZX lathe combines heavy-duty industrial construction, powerful geared headstock performance, and the largest turning capacity in JET’s GH-ZX series. Designed for professional machine shops, heavy fabrication facilities, industrial maintenance departments, and large-component repair operations, this 21″ x 80″ metal lathe provides the power and rigidity required for turning, facing, boring, drilling, threading, grooving, and general machining operations.

Powered by a 10 HP, 230V three-phase motor, the GH-2180ZX delivers substantial cutting power for machining large workpieces and demanding materials. Its geared headstock provides 12 selectable spindle speeds ranging from 26 to 1,500 RPM, allowing operators to choose appropriate speeds for different materials, cutting tools, and machining requirements.

With a 21″ swing over the bed and an actual 83.5″ distance between centers, the machine accommodates large and lengthy industrial workpieces, including shafts, rollers, hydraulic cylinder components, threaded bars, and precision-machined replacement parts.

The GH-2180ZX also offers a 28.7″ swing through the gap, providing additional clearance for short, larger-diameter workpieces when the removable gap section is properly configured.

One of the machine’s standout features is its 3-1/8″ spindle bore, which allows larger-diameter bar stock to pass through the headstock. This through-spindle capacity can help reduce material handling, unnecessary cutoffs, and repeated workpiece repositioning.

The JET GH-2180ZX lathe features a D1-8 camlock spindle mount, MT7 spindle taper, MT5 spindle taper with sleeve, and MT4 tailstock taper for compatibility with appropriately sized chucks, centers, and industrial workholding equipment.

Its rigid one-piece cast iron base helps dampen vibration and resist machine deflection during heavier cutting operations, supporting dimensional consistency and surface finish quality across large workpieces.
