VKC-40 independent four-jaw chuck – 1000 mm diameter, 150 rpm (Vertex)

The VKC-40 is an independent four-jaw chuck designed for heavy-duty turning of large-diameter components in workshop and production environments.

• Robust 536 kg body for heavy work
• 1000 mm clamping diameter
• Independent jaws for flexible centring

Large-diameter capacity for stable, precise turning

The chuck offers a 1000 mm clamping diameter and a substantial mass that translates into stability during machining. With a rated rotational speed of 150 rpm, the solution is optimised for heavy, slow-speed turning where vibration damping and consistent contact pressures reduce chatter and rework. The substantial construction supports repeatable mounting and contributes to consistent precision across long production runs.

Flexible centring that reduces setup complexity

Featuring independent jaws, the workholding solution enables centring of asymmetrical or irregular components without relying on self-centring forces. This flexibility shortens setup time for bespoke workpieces and small series, while allowing precise, manual adjustment of each jaw. The specified T-nut 8-M20 interface provides a clear mounting standard for attachment and fixture integration, supporting varied clamping arrangements and accessory use.

Robust design for continuous heavy-duty operation

Built for demanding environments, the chuck combines a rugged construction with a form factor suited to large-part turning. The design prioritises secure clamping and mechanical endurance so that the workholding remains reliable under sustained loads. As a Vertex-manufactured workholding solution the unit is intended to integrate into production lines where predictable performance and longevity reduce downtime and overall machining costs.
