Vertex VKC-12B – Four-jaw independent chuck, 320 mm, 850 r.p.m.

The VKC-12B is a four-jaw independent chuck designed for flexible workholding on medium and large lathes, allowing precise clamping of asymmetrical and irregular parts.

• Independent jaw control for flexible clamping
• 320 mm diameter for larger workpieces
• Rated up to 850 r.p.m. for high productivity
• Mounting via 4‑M16 T‑slots for secure fixing

Precision clamping for irregular and asymmetrical parts

A four-jaw independent chuck provides individual jaw movement, enabling the accurate centring of off-centre or irregular components without the need for custom fixtures. With a 320 mm clamping diameter, the device accommodates larger blanks while maintaining precision thanks to separate jaw adjustment. This configuration reduces setup complexity for odd-shaped workpieces and improves first-pass accuracy, which in turn lowers rework rates and supports a smoother production flow.

Robust build for stable, productive turning

Engineered for repetitive machining, the chuck’s mass and construction deliver stability during operation; the specified 850 r.p.m. rating indicates the safe rotational speed for the unit under normal conditions. At approximately 21.8 kg, the assembly contributes inertia that helps dampen vibration when cutting, supporting consistent surface finish and dimensional stability. The combination of mechanical sturdiness and the elevated speed limit offers a balance between productivity and operational safety in daily shop use.

Simple mounting and practical workshop integration

Mounting utilises 4‑M16 T‑slots, enabling secure attachment to standard lathe faceplates and simplifying installation in existing setups. The independent jaw concept reduces reliance on soft jaws or elaborate fixtures for many tasks, shortening changeover times and increasing machine uptime. Supplied via Metav Werkzeuge, the chuck is part of a curated range intended to make high-precision clamping accessible to workshops while ensuring a consistent quality filter for the European market.
