Jet 321122 Gap Bed Lathe Acu-rite 200S Dro

Product Description

The JET 321122 is the GHB-1340A gap bed lathe with an ACU-RITE 200S digital readout (DRO) factory installed. This is a heavy-duty manual turning machine intended for metal fabrication shops, maintenance facilities, and industrial training environments. The integrated ACU-RITE 200S DRO provides real-time axis position readout, reducing setup time and improving dimensional repeatability on turned parts. At 1215 pounds, this is a full-size floor lathe requiring proper rigging and a prepared machine foundation before installation. Licensed machinists and industrial equipment technicians are the typical installers.

The GHB-1340A platform is a gap bed design, which allows for turning larger-diameter workpieces when the gap section ahead of the chuck is removed. This configuration suits shops that handle a mix of standard turning work and occasional large-flange or disc-type parts. The factory-installed ACU-RITE 200S DRO eliminates field retrofit labor and ensures the scales and display are aligned and calibrated from the manufacturer. Typical applications include precision shaft turning, facing, threading, and boring operations in job shop and maintenance machining environments.

Key Features

• Gap bed construction allows turning of oversized-diameter workpieces with gap section removed
• ACU-RITE 200S DRO factory installed for out-of-the-box digital axis readout
• Full machine weight of 1215 pounds indicates a rigid, heavy cast iron construction
• Sold as a single complete unit including lathe and DRO system

Compatibility

The ACU-RITE 200S DRO is factory installed on the JET GHB-1340A gap bed lathe as a matched assembly. Replacement scales, display heads, or accessory components should be sourced to match the ACU-RITE 200S system specifications.

Installation Notes

At 1215 pounds, this machine must be moved and placed using appropriate rigging equipment such as a forklift or overhead crane — never attempt to roll or drag the unit on its base casting. The lathe should be leveled on a reinforced concrete floor using precision leveling feet and a machinist level before any power connection is made. Electrical connection should be performed by a licensed electrician in accordance with applicable NEC requirements for the machine voltage and phase configuration. Confirm local utility supply matches the machine nameplate before energizing.
