Value Collection 429-3752 Lathe Chuck Adapter Back Plate

Product Description

The VALUE COLLECTION 429-3752 is a lathe chuck adapter back plate designed to mount a 12-inch chuck to a D1-11 spindle nose using the D Series camlock interface. This back plate serves as the mechanical interface between the machine spindle and the chuck body, transmitting torque and providing a flat, precision-machined seating surface. It is installed by machinists and toolroom technicians on engine lathes and CNC turning centers equipped with a D1-11 spindle nose. The part is designed to the standard D Series geometry, ensuring repeatable chuck positioning and secure camlock engagement during turning operations.

This back plate is suited for use on engine lathes, manual turning centers, and similar machine tool platforms that feature a D1-11 camlock spindle nose. It is sized for 12-inch chuck bodies and is a common replacement or upgrade component in production and job-shop environments where chuck swaps or spindle rebuilds require a new mating plate. Installation is typically performed during scheduled maintenance, chuck changeovers, or spindle reconditioning work.

Installation Notes

Installation should be performed by a qualified machinist or toolroom technician. Disconnect and lock out power to the lathe before handling any spindle or chuck components. Inspect the spindle nose camlock pins and the back plate bore for burrs, damage, or contamination before seating the plate. Torque and seating procedures should follow the machine tool manufacturer's guidelines and applicable shop safety standards.
