Jet 321389 GH-1660ZX Lathe with Dro Taper Attachment

Product Description

The JET 321389 is a gap bed engine lathe configured as the GH-1660ZX model, equipped with a 300S digital readout (DRO) and a taper attachment. Built for precision turning operations, this lathe is designed for machine shops, maintenance facilities, and industrial production environments where accurate material removal and repeatable setups are essential. The included DRO provides real-time axis position feedback, reducing setup time and improving dimensional accuracy. The taper attachment allows machinists to cut precise tapers without offsetting the tailstock, preserving alignment for subsequent operations. At 5,925 pounds, this is a heavy-duty floor machine requiring proper rigging and a prepared concrete foundation.

The GH-1660ZX lathe is suited for professional machine shops, tool rooms, and industrial maintenance departments handling shaft work, threading, facing, and taper turning. The combination of a gap bed design, integrated DRO, and taper attachment makes this unit appropriate for facilities that require versatile, high-capacity turning capability on a single machine platform. Installation and operation are performed by qualified machinists or millwrights familiar with large engine lathe setup and alignment procedures.
