Secure and precise workholding for turning operations
Drehfutter, known in English as chucks or jaw chucks, provide secure, high‑radial clamping of cylindrical, hexagonal or irregular components to ensure vibration‑free rotation and accurate machining. As central workholding devices on conventional and CNC lathes, they use adjustable jaws—commonly three‑jaw chucks for round and hex stock and four‑jaw chucks for square or odd‑shaped parts—to clamp externally or expand internally for hollow workpieces, enabling consistent runout accuracy, fast workpiece changeover and robust process stability during heavy roughing and precision turning.

Take advantage of the combination of precise, repeatable clamping and robust workshop performance thanks to the self-centring 6-jaw design and a nominal diameter of 112 mm. Order directly via Metav Werkzeuge or consult our team for technical guidance and matching accessories. 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.

Secure, repeatable clamping for high-throughput turning
Lathe chucks — also referred to as a lathe chuck, jaw chuck or workholding chuck — are the central workholding devices on conventional and CNC turning centres. They fix cylindrical, hexagonal or asymmetric blanks and machined components concentrically with high radial clamping force, so rotation is transferred to the workpiece without slip and with minimal vibration.
How reliable clamping speeds up production
In practice, chucks use radial adjustable jaws; three-jaw chucks are typical for round and hexagonal stock, while four-jaw chucks handle square or irregular parts. Clamping can be external (outside diameter) or internal (from inside a hollow part). Operation ranges from manual hand chucks, using a key and integrated scroll plate for synchronous jaw movement, to power chucks actuated hydraulically or pneumatically via a drawbar for constant, high clamping forces and rapid, automated workpiece changes. The result is improved concentricity, lower scrap rates and stable machining under high cutting loads.
Key benefits at a glance
- consistent concentricity and reduced runout
- high radial clamping force for vibration dampening during heavy cuts
- shorter set-up times through power-actuated quick change options
- flexible clamping modes: external and internal holding for diverse part geometries
- process reliability and machine protection via robust stiffness and balance

FAQ
What applications are lathe chucks suited for?
Lathe chucks are suited for turning operations on conventional and CNC machines where secure, concentric clamping of round, hexagonal or irregular parts is required.
When should I choose a three-jaw chuck over a four-jaw chuck?
Choose a three-jaw chuck for fast, repeatable clamping of round or hexagon stock; use a four-jaw chuck for square, rectangular or irregular workpieces where independent jaw adjustment is needed.
Can power chucks reduce cycle time in series production?
Yes. Power chucks provide rapid, consistent clamping and enable automated workpiece changes, which reduces set-up time and increases throughput in serial production.
How do chucks protect the machine and the process?
By ensuring high stiffness, low runout and stable balancing, chucks minimise vibration and uneven loads, safeguarding both the workpiece accuracy and the machine tool.
What alternative terms describe this category?
Common synonyms used in industry are lathe chuck, jaw chuck and workholding chuck, all referring to the same class of workholding devices.
