Jet 321531 Gap Bed Lathe with Collet Closer

Product Description

The JET 321531 is the GH1440ZX gap bed engine lathe configured with a collet closer pre-installed at the factory. This unit is a full-size metalworking lathe built for precision turning operations in machine shops, maintenance facilities, and production environments. The collet closer installation allows operators to quickly secure collets for accurate, repeatable workholding without additional setup. At 5,700 pounds, this is a heavy-duty floor machine intended for permanent installation on a prepared shop floor. Licensed machinists and skilled trade professionals are the primary installers and operators of this equipment.

The GH1440ZX configuration indicates a 14-inch swing over the bed and a 40-inch distance between centers, making it well suited for medium to large diameter turning, facing, threading, and boring work in industrial and job shop settings. The pre-installed collet closer adds versatility for high-precision collet-based workholding directly out of the crate, reducing commissioning time. This lathe is appropriate for both production runs and one-off precision machining tasks where consistent workpiece concentricity is required.

Key Features

• Collet closer pre-installed at the factory for immediate collet-ready operation
• Gap bed design allows turning of larger diameter workpieces near the chuck
• Heavy cast iron construction at 5,700 pounds supports rigid, vibration-dampened cuts
• 14-inch swing and 40-inch center distance accommodate a wide range of workpiece sizes
• Intended for permanent shop floor installation on a level, reinforced surface

Compatibility

Designed as a factory-configured variant of the JET GH1440ZX engine lathe platform with the collet closer integrated. Confirm tooling and collet sizes are compatible with the installed collet closer specification before ordering accessories.

Installation Notes

Installation of this lathe should be performed by qualified millwrights or mechanical contractors experienced with heavy machine tool placement. The machine must be set on a level, structurally adequate concrete floor and properly anchored before operation. Electrical connection must be completed by a licensed electrician in accordance with applicable NEC requirements for the machine voltage and phase rating. Disconnect and lock out all power sources before performing any maintenance, tooling changes, or collet closer adjustments.
