Value Collection 333.12400339 Low Profile Machining Chuck

Product Description

The VALUE COLLECTION 333.12400339 is a low profile machining chuck designed for use on CNC lathes and turning centers where workholding clearance is a critical factor. With a 12-inch chuck diameter and an external chucking range of 15 mm to 300 mm, this chuck accommodates a wide variety of workpiece diameters in a single setup. The reduced-height body measures 45 mm overall, making it well-suited for operations where the chuck must clear the machine bed, tailstock, or tooling at close proximity. At 93 pounds, this is a substantial workholding device intended for professional machine shop installation and setup.

This low profile chuck is used in production and job-shop turning environments where standard-height chucks create interference with the machine envelope. It is appropriate for both horizontal and vertical lathe configurations where minimizing stack height between the spindle face and the workpiece is essential. The 15 mm minimum and 300 mm maximum external chucking diameter range supports a broad spectrum of shaft, flange, and ring-type workpieces. Installation and mounting are performed by qualified machine operators or setup technicians familiar with lathe spindle interface standards.

Key Features

• Low profile body at 45 mm overall height reduces clearance conflicts during turning operations
• 12-inch chuck diameter provides a large gripping face suitable for substantial workpieces
• External chucking range of 15 mm to 300 mm supports diverse workpiece sizes without chuck change
• Heavyweight construction at 93 pounds indicates robust, rigid clamping body for stable cuts
• UNSPSC Code 27112100 for procurement and catalog classification

Compatibility

Designed as an OEM-style replacement or direct-fit workholding chuck for lathes and turning centers accepting a 12-inch chuck mounting configuration. Verify spindle nose interface type and bolt circle pattern against machine specifications before installation.

Installation Notes

Installation must be performed by a qualified machinist or setup technician. Always power down and lock out the lathe spindle drive before mounting or removing the chuck. Verify that the spindle nose interface, bolt circle diameter, and thread pattern of the machine match the chuck backplate or adapter being used. Due to the 93-pound weight of this chuck, use appropriate lifting equipment or a chuck cradle to prevent injury and spindle damage during mounting.
