Jet 321439 Lathe with Collet Closer

Product Description

The JET 321439 is a heavy-duty gap-bed engine lathe with an integrated collet closer, designed for precision turning operations in machine shops and industrial environments. Weighing 5,675 pounds, this is a floor-standing production lathe built for serious metal removal. The collet closer allows fast, repeatable workpiece clamping without a chuck change, reducing setup time during high-cycle operations. Licensed machinists and skilled trade professionals are the primary installers and operators of this machine.

The JET 321439 GH-1640ZX suits production machine shops, tool rooms, and heavy industrial facilities where consistent turning accuracy is required. The lathe is configured for metal turning applications including facing, threading, boring, and taper turning. Its substantial mass provides vibration damping that supports tight tolerances across extended production runs.

Key Features

• Integrated collet closer for rapid, repeatable workpiece clamping
• Heavy cast iron construction supports vibration-free cutting
• Floor-standing gap-bed design accommodates larger diameter workpieces
