Jet 321477 Geared Head Lathe Taper Attachment

Product Description

The JET 321477 is a geared head engine lathe with a factory-installed taper attachment, designed for precision turning operations in machine shops and industrial maintenance environments. The GH-1660ZX designation indicates a 16-inch swing and 60-inch distance between centers, making it suited for medium to large workpieces. At 6200 pounds, this is a heavy-duty floor machine built for stable, high-accuracy work. Machinists and tool-and-die professionals install and operate this equipment for production turning, facing, threading, and taper work without requiring a separate taper turning setup.

The GH-1660ZX TAK is intended for professional machine shops, industrial maintenance facilities, and vocational or technical training programs that require full-featured engine lathe capability. The factory-installed taper attachment expands the machine's capability for angled turning and boring without manual offsetting of the tailstock. This configuration is common in environments where taper turning is a routine operation and downtime for setup changes is not acceptable.

Key Features

• Factory-installed taper attachment included — ready for taper turning out of the crate

• 16-inch swing accommodates medium to large-diameter workpieces
• 60-inch between-centers capacity for long-shaft and extended workpiece turning

Compatibility

Designed as an OEM-configured geared head engine lathe; the 321477 is the specific JET part number for the GH-1660ZX model with taper attachment installed. Consult JET documentation for compatible tooling, chuck adapters, and accessory specifications.

Installation Notes

Installation of a floor lathe of this size and weight requires a certified rigger or millwright and appropriate lifting equipment rated for the machine weight. The machine must be leveled on a reinforced concrete floor using precision leveling methods before commissioning. Electrical connection should be performed by a licensed electrician in accordance with the NEC and local codes. Always verify spindle is disengaged and power is locked out before performing any tooling changes or maintenance.
