Lathe chuck VSK-10A — 3‑jaw self‑centring and reversible clamping, Vertex

The lathe chuck VSK‑10A is a robust, industrial‑grade 3‑jaw chuck designed for secure, repeatable clamping in turning operations; it is suited to workshop and production lathes where reliable concentricity and quick jaw reversal are required.

• Self‑centring 3‑jaw design
• Reversible for front/back mounting
• 250 mm diameter for larger workpieces
• Robust 21.7 kg steel construction

Consistent concentricity for precision turning

The self‑centring mechanism of the 3‑jaw system ensures rapid alignment between chuck and workpiece, reducing setup time while maintaining concentricity across repeated cycles. This benefit translates into fewer rejects and less rework when producing turned components with close tolerance requirements. The large 250 mm grip diameter accommodates bigger parts without sacrificing stability, making the unit suitable for medium to heavy turning operations where steady clamping is essential for surface finish and dimensional control.

Flexible mounting and vibration damping for steady cuts

A reversible configuration allows assembly on the spindle face or reversed for back‑mounting, supporting diverse machining setups and short changeovers between operations. The chuck’s 3x M12 mounting thread pattern provides secure attachment to common spindle noses, while the substantial 21.7 kg mass and 120 mm height assist in dampening chatter and vibration. The resulting stability supports higher cutting performance and predictable tool life, which together improve machine utilisation and process reliability in serial production.

Durable design for continuous workshop use

Constructed for industrial duty, the workholding unit offers a balance of ruggedness and manageable maintenance. The reversible jaw arrangement simplifies indexing and extends the useful life of the jaws, while the solid build reduces deformation under load, preserving clamping force and repeatability. For operations that demand steady throughput and low downtime, the combination of hardened components and straightforward mechanical design ensures long service intervals and predictable maintenance planning, supporting overall operational efficiency and confidence in daily production routines.

FAQ

How does the self‑centring mechanism affect setup time?
The self‑centring action of the lathe chuck VSK‑10A (Vertex 3‑jaw chuck, SKU VSK‑10A) reduces manual alignment, cutting setup time and improving repeatable positioning.

Can the chuck be mounted both front and back on the spindle?
Yes, the reversible design allows both front and back mounting, offering flexible installation options for different turning setups.

What spindle mounting interface is used?
The unit uses a 3x M12 mounting thread pattern for secure attachment to compatible spindle noses.

Will the chuck’s weight help reduce vibration during turning?
The robust 21.7 kg mass contributes to vibration damping, which supports steadier cuts and can extend tool life in demanding operations.

Is the VSK‑10A suitable for larger workpieces?
With a 250 mm grip diameter and a sturdy construction, the VSK‑10A is suitable for larger turning jobs where reliable clamping and concentricity are required.
