JET GH-2680ZH Large Spindle Bore Industrial Geared Head Lathe
The JET GH-2680ZH lathe is engineered for demanding industrial turning applications that require high horsepower, substantial workpiece capacity, and heavy-duty machine construction. Designed for professional machine shops, industrial maintenance departments, fabrication facilities, and equipment repair operations, this 26″ x 80″ metal lathe provides the power and rigidity required for turning, facing, boring, drilling, threading, and general machining of large components.
Powered by a 15 HP, 230V three-phase motor, the GH-2680ZH delivers the power needed for demanding cutting operations on large-diameter materials. Its geared headstock offers 12 selectable spindle speeds ranging from 10 to 1,000 RPM, providing low-speed capability for heavy workpieces and higher speeds for appropriate finishing operations.
With a 26″ swing over the bed and 80″ distance between centers, the GH-2680ZH accommodates large and lengthy workpieces such as industrial shafts, rollers, hydraulic cylinder components, pipe, and precision-machined replacement parts.
The machine also provides a 35″ swing through the gap, offering additional clearance for short, oversized components when the removable gap section is properly configured.
A standout feature of the GH-2680ZH is its 4-1/2″ spindle bore, which allows larger-diameter bar stock and pipe to pass through the headstock. This increased through-spindle capacity can help reduce material handling and simplify machining operations involving long or heavy stock.
The D1-11 camlock spindle mount supports compatible heavy-duty chucks and workholding equipment designed for larger workpieces. An MT7 spindle taper, MT5 spindle taper with sleeve, and MT5 tailstock taper provide additional tooling compatibility.
The GH-2680ZH is built on a rigid one-piece cast iron base that helps control vibration and maintain stability during demanding machining operations. Its 15.75″ bed width provides a substantial foundation for the carriage and tailstock.
