Abbott Workholding Products AL363 Soft Lathe Chuck Jaw

Product Description

The ABBOTT WORKHOLDING PRODUCTS AL363 is a soft lathe chuck jaw designed for precision workholding on manual and CNC lathes. Machined from 2024 aluminum, this round jaw uses a tongue and groove interface to seat securely in compatible 3-jaw chuck bodies. With a maximum internal and external chucking diameter of 5.75 inches and a minimum chucking diameter of 0.75 inches, it covers a broad range of workpiece sizes. The 3-inch overall height provides adequate gripping surface for both stub and extended workholding applications. Weighing 7.5 pounds, the set is suited for machine shops and production turning operations.

This soft jaw is intended for use in lathe turning operations where a machinable jaw is required to match a specific workpiece profile. Because the aluminum material machines easily, technicians can bore or turn the jaw face to a custom diameter, radius, or contour without specialized tooling. It is appropriate for both internal and external chucking setups in job shop, toolroom, and production environments. The jaw set is sold as a single unit and is compatible with 6-inch chuck bodies using a tongue and groove interface.

Key Features

• Machinable 2024 aluminum construction allows custom boring to exact workpiece geometry
• Maximum internal and external chucking diameter of 5.75 inches for versatile part holding
• Minimum chucking diameter of 0.75 inches for small-bore and close-tolerance work
• Round jaw shape with tongue and groove interface for positive, repeatable seating
• 3-inch overall height provides stable gripping depth for a range of workpiece lengths
• 3-jaw configuration for balanced clamping force around the workpiece circumference

Compatibility

Designed for use with 6-inch diameter lathe chuck bodies that accept a tongue and groove, round soft jaw interface. Verify chuck jaw slot geometry and bolt pattern against existing chuck hardware before installation.

Installation Notes

Soft jaw installation and machining should be performed by a qualified machinist or lathe operator. Before mounting or boring the jaws, power down and lock out the lathe per facility lockout/tagout procedures. Clamp the jaws under light load when boring to replicate actual chucking conditions and minimize runout after release. Inspect the tongue and groove fit for full seating and confirm all jaw bolts are torqued evenly before returning the chuck to service.
