VSC-12 three-jaw chuck – 310 mm diameter, 5,700 kgf clamping force (Vertex)

The VSC-12 three-jaw chuck is a robust workholding device for turning applications, designed to grip a wide range of cylindrical parts securely and maintain concentricity during machining.

Large 310 mm diameter for big workpieces
High 5,700 kgf clamping force for secure hold
Precision 0.03 mm runout accuracy
Rated up to 1,800 rpm operational speed

Stable clamping for uninterrupted turning

The chuck’s design focuses on dependable holding power: with a 5,700 kgf clamping force and a 310 mm diameter capacity, the device secures medium to large components for turning operations. That level of grip reduces slippage and tool interruptions, which directly improves throughput. The mechanical configuration of the three-jaw chuck ensures uniform load distribution, so the workpiece remains centred under load—translating technical strength into a measurable production advantage.

Precision that reduces rework and improves finish

Accuracy plays a central role in reducing scrap. Featuring 0.03 mm runout accuracy, this chuck minimises off-centre turning and vibration, helping to achieve tighter tolerances and a better surface finish. For shops moving parts between setups, consistent concentricity reduces alignment cycles and secondary operations. The precise clamping performance therefore shortens machining times and lowers the risk of rework, delivering a clear return in efficiency and component quality.

Engineered for workshop workflows and safe operation

Rated for operation up to 1,800 rpm, the chuck is suitable for a wide range of lathe speeds while maintaining balance and stability. The three-jaw configuration is well suited to quick chucking and repeatable setups, which supports lean workflows on production lines and jobbing shops alike. Built to integrate into standard turning equipment, the device contributes to smoother changeovers and predictable cycle times — a practical advantage for busy workshop schedules.

FAQ

What size of workpiece can be held by this chuck?
The chuck accommodates workpieces up to a nominal 310 mm diameter; the VSC-12 three-jaw chuck is intended for medium to large cylindrical parts.

How does the specified accuracy affect turning quality?
With 0.03 mm runout accuracy, the chuck helps maintain concentricity during machining, which improves surface finish and reduces the need for corrective rework on parts produced with the VSC-12.

Is the VSC-12 suitable for high-speed turning?
The device is rated up to 1,800 rpm, and it is balanced to operate reliably at that speed for standard turning applications.

What kind of machines is this chuck compatible with?
The three-jaw configuration is compatible with conventional lathes and turning centres that accept a chuck of this diameter and mounting type; specific mounting requirements should be confirmed for each machine.

Can the chuck maintain grip on irregular or slightly tapered parts?
The three-jaw design provides uniform radial clamping for round and near-round geometries; for irregular shapes, specialised jaws or workholding solutions may be required.
