VSK-9 workholding chuck — 232 mm diameter, 3,900 kgf clamping force (Vertex)

The VSK-9 is a heavy-duty workholding chuck engineered to secure large rotating workpieces for CNC turning and related machining tasks, prioritising repeatability and machining stability.

• 232 mm nominal diameter
• 3,900 kgf clamping force
• 0.03 mm repeatability accuracy
• Up to 2000 r.p.m. operational speed
• Robust 20.4 kg construction

Precision clamping for consistent machining results

The chuck delivers repeatable accuracy of 0.03 mm, a level that reduces concentricity errors and minimises rework on turned components. Such precision is beneficial when maintaining tight tolerances across production batches, because the stable clamping reduces runout and helps preserve tool geometry. In practical terms, the combination of high clamping force and measured repeatability supports finer surface finishes and predictable dimensional results, making the device suitable where consistent quality is essential.

Designed to enhance productivity and reduce downtime

With a 232 mm nominal diameter and an operational limit of 2000 r.p.m., the unit accommodates larger workpieces while balancing rotational speed and holding stability. The substantial mass of 20.4 kg contributes to damping of spindle vibrations, which in turn can extend cutting tool life and lower scrap rates. These factors create a tangible efficiency gain on the shop floor: fewer interruptions for rework, steadier cycle times and a smoother production flow when used in repetitive turning operations.

Practical integration and routine care for long service life

The chuck is intended for straightforward integration into standard workshop workholding setups and benefits from routine checks of clamping force and runout. Periodic inspection ensures the 3,900 kgf clamping capability remains within specification and that the 0.03 mm accuracy is retained under operational conditions. Simple maintenance—cleaning contact surfaces, verifying torque settings and replacing wear parts as needed—keeps the unit performing reliably, which supports continuous production without unexpected stoppages.

Applications that profit from secure, high-force clamping

This workholding solution is especially suitable for machining large-diameter components where secure grip and concentricity are priorities. The robust clamping capacity supports operations that require higher cutting forces or interrupted cuts, improving process stability and operator confidence. Backed by Vertex engineering and supplied through Metav Werkzeuge, the chuck aligns with workshop needs for durable, dependable workholding that scales to industrial demands.
