Jet 321515A Collet Closer Bdb Series Lathes

Product Description

The JET 321515A is a collet closer designed for use with BDB-series lathes. A collet closer allows machinists to quickly and securely clamp workpieces using collets rather than a standard chuck, improving repeatability and reducing setup time on the lathe. This unit is a direct-fit accessory for compatible BDB-series machines and is installed by machinists and toolroom professionals working in production or job-shop environments. At 22.25 pounds, the 321515A is a substantial, shop-grade component built for regular use on metal-cutting lathes.

This collet closer is intended for use on JET BDB-series lathes in machine shop settings, including small production runs, tool and die operations, and general metal turning applications. It is suited for both professional shop environments and skilled trades installations where collet-based workholding is preferred over conventional jaw chucks for improved concentricity and faster part changeover.

Key Features

Compatibility

Designed for use with JET BDB-series lathes, as indicated by the CC-BDB1340A designation. Verify spindle bore and collet series compatibility with your specific BDB model before installation.

Installation Notes

Installation should be performed by a qualified machinist familiar with lathe spindle components and workholding systems. Power down and lock out the lathe at the main disconnect before removing or installing any spindle-mounted accessories. Consult the lathe manufacturer's documentation for proper mounting procedure and spindle engagement specifications. Do not operate the lathe until the collet closer is fully seated and secured per the machine manual.
