Jet 321940 Geared Head Lathe 16in 60in 7.5HP 3ph

Product Description

The JET 321940 is a geared head gap-bed engine lathe built for heavy-duty turning operations in professional machine shops and industrial facilities. This unit features a 16-inch swing over the bed and 60 inches between centers, giving machinists ample capacity for large-diameter and long-workpiece applications. The D1-8 Camlock spindle nose allows fast, accurate chuck changes without sacrificing rigidity. Power comes from a 7.5 HP, 3-phase motor wired for 230 or 460 volts, delivering the torque needed for continuous production cutting in ferrous and non-ferrous materials. Installation and commissioning are typically handled by millwrights or industrial maintenance technicians.

This lathe is suited for production turning, facing, threading, boring, and taper turning in commercial machine shops, toolrooms, and maintenance facilities. The 16-inch swing and 60-inch center distance make it appropriate for medium-to-large shaft, sleeve, and cylinder work. The 3-phase power requirement means it is intended for industrial facilities with adequate electrical service. It is not a light-duty or hobbyist machine.

Key Features

• 16-inch swing over bed for large-diameter turning capacity
• 60 inches between centers accommodates long workpieces
• D1-8 Camlock spindle nose for rapid, repeatable chuck mounting

Compatibility

The 321940 is the JET GH-1660ZX geared head lathe. Accessories and tooling compatible with a D1-8 Camlock spindle nose are directly applicable to this machine.

Installation Notes

Installation should be performed by a qualified millwright or industrial electrician. Verify that the facility electrical service matches the required 3-phase, 230 or 460-volt supply before connecting power, and ensure the disconnect is locked out before any wiring work is performed. The machine must be leveled and anchored to a solid concrete floor per the manufacturer's installation manual and applicable local codes. Do not operate without proper guarding in place.
