VAS-6 – 6‑jaw self‑centring chuck, Ø 167 mm, Vertex

The VAS-6 is a 6‑jaw self‑centring chuck for lathe workholding, engineered to provide consistent clamping and fast set-up for production and workshop applications

• 6-jaw self-centring design
• Diameter 167 mm for medium workpieces
• Max speed 1,200 r.p.m. for efficient turning
• Robust construction, 9.2 kg mass

Repeatable centring for consistent part quality

The 6-jaw layout delivers uniform gripping force around the workpiece, reducing runout and improving repeatability across batch production. The self-centring mechanism shortens setup times compared with independent-jaw systems, which supports higher throughput without sacrificing accuracy. For operations where concentricity and surface finish are critical, the chuck’s geometry helps maintain steady cutting conditions and predictable results.

Balanced mass and speed for stable machining

A mass of 9.2 kg combined with a rated maximum of 1,200 r.p.m. provides a stable rotating assembly that resists chatter in medium‑duty turning. The Ø 167 mm jaw span suits a wide range of round and slightly irregular components often encountered in maintenance, prototyping and small-series manufacture. Clear specification of rotational speed supports process planning and helps avoid exceeding safe operational limits during roughing and finishing passes.

Practical integration and workshop efficiency

Designed for straightforward mounting in standard lathe setups, the chuck simplifies workholding choices and reduces the number of bespoke fixtures required. The robust construction supports frequent clamping cycles in daily workshop use, while the compact footprint preserves access to tooling and measurement points. Combining predictable clamping behaviour with straightforward handling, this chuck supports leaner workflows and reduces non-productive time in the machine cycle.

FAQ

How does the 6-jaw design affect concentricity?
The six-jaw layout increases contact points and balances clamping forces, so the VAS-6 achieves improved concentricity and repeatability compared with three-jaw designs for many medium-sized parts.

What is the maximum safe rotational speed for this chuck?
The chuck is rated to operate at up to 1,200 r.p.m., which should be observed to ensure safe and stable machining conditions when the VAS-6 is mounted.

Which workpiece diameters are suitable for this chuck?
With a diameter of 167 mm, the chuck is intended for medium workpieces commonly processed in general workshop and light production turning operations.

Can the chuck be used for high-precision finishing operations?
Yes, the self-centring mechanism and uniform jaw engagement of the VAS-6 support finishing passes where concentricity and surface consistency are required.
