VAS-4 Self-centring 6-jaw chuck, 112 mm — Vertex

The VAS-4 is a 6-jaw, self-centring chuck designed for reliable workholding in turning and machining applications where concentricity and repeatable clamping are required.

• Self-centring 6-jaw design for precise gripping
• 112 mm nominal diameter for medium workpieces
• Max. 1,200 r.p.m. for reliable rotational control
• Robust 4.2 kg construction for stable clamping

Consistent concentricity for repeatable parts

A self-centring jaw system ensures that all six jaws close simultaneously, producing consistent concentricity across repeated setups. This mechanical symmetry reduces the need for manual realignment and lowers scrap rates in serial production. The six-jaw arrangement provides more contact points than a three-jaw variant, improving grip on irregular or thin-walled components while maintaining stable clamping. The result is tangible time savings at the spindle and more predictable part quality in turning operations.

Quicker setups and safer machining cycles

Because the jaws move in unison, clamping is faster and less dependent on skilled manual adjustment, shortening the overall cycle time for batch work. The chuck’s specified maximum speed of 1,200 r.p.m. matches many medium-speed turning tasks, allowing operators to maintain cutting parameters without compromising safety. The balanced design supports steady running at operational speeds, preserving tool life and reducing vibration-related defects. Clear documentation of rotational limits helps planners select appropriate cutting data for each job.

Stability and workshop-ready construction

With a mass of 4.2 kg, the workholding device provides the inertia necessary to damp vibration and maintain position during heavier cuts. The solid build contributes to overall stability at the tool–workpiece interface, which is particularly valuable when machining slender or asymmetrical components. Durable construction translates into longer service intervals and reliable repeatability shift after shift, supporting higher throughput in a production environment.

Practical handling and maintenance guidance

The chuck is designed for straightforward mounting and routine inspection; regular checks of jaw alignment and mounting bolts preserve precision and extend service life. When installing, ensure compatibility with the machine spindle and follow established safety procedures for clamping and removal. Replacement parts and spares should be kept on hand to minimise downtime; Metav Werkzeuge can advise on suitable accessories and service items for workshop inventory planning.

FAQ

What is the nominal diameter of the chuck?
The chuck has a nominal diameter of 112 mm, suitable for a range of medium-sized turning tasks.

What maximum rotational speed is recommended?
The device is specified for up to 1,200 r.p.m.; this limit should be observed to maintain safe and vibration-free operation.

Is the chuck self-centring?
Yes — the self-centring six-jaw configuration ensures synchronous jaw movement for improved concentricity and repeatable clamping.

How heavy is the chuck and what does that mean for stability?
Weighing 4.2 kg, the chuck provides mass that helps damp vibration and contributes to greater stability during machining.

Which SKU and manufacturer should be referenced when ordering accessories?
Reference SKU VAS-4 and Manufacturer Vertex when enquiring about replacement jaws or mounting kits.
