Value Collection 262-4120 Expanding Lathe Arbor 1.5 in Face Dia

Product Description

The VALUE COLLECTION 262-4120 is an expanding lathe arbor designed to hold workpieces securely on a lathe by gripping from the inside bore. The expanding mechanism applies outward radial pressure against the workpiece ID, providing positive, concentric workholding without relying on external clamping. The face diameter measures 1.5 inches and the overall length is 4 inches. This arbor is installed and used by machinists and toolroom operators in metalworking, production turning, and precision grinding operations where accurate, repeatable part location is required.

This expanding lathe arbor is suited for use in manual engine lathes and CNC turning centers where inside-diameter workholding is needed. Typical applications include finish-turning, facing, and grinding operations on bushings, rings, sleeves, and similar bored components. The 4-inch overall length provides adequate clearance and rigidity for a range of part lengths at the 1.5-inch face diameter. It is commonly used in job shops, toolrooms, and light manufacturing environments.

Key Features

• 1.5 inch face diameter for inside-bore workholding
• 4 inch overall length provides rigidity and clearance for typical turning operations
• Expanding design centers and clamps workpieces concentrically from the ID
• Suitable for turning, facing, and grinding applications on bored parts
• Compact weight of 1.65 pounds for easy handling and setup

Compatibility

Designed as a standard expanding lathe arbor for use on manual engine lathes and CNC turning centers that accept arbor-style workholding tooling at a 1.5-inch face diameter.

Installation Notes

Installation is performed by a machinist or toolroom operator. Ensure the lathe spindle is fully stopped and the machine is powered down before mounting or removing the arbor. Verify the workpiece bore is clean and free of burrs before seating the arbor to ensure accurate concentricity. Follow the lathe manufacturer guidelines and applicable shop safety procedures when setting up workholding tooling.
