Combine the 3‑jaw self‑centring design with a 160 mm nominal diameter and reversible operation to increase clamping reliability and reduce setup time; order via Metav Werkzeuge or consult the technical team for application advice.

VSK-6A Spannfutter – 3‑jaw self‑centring reversible chuck (Vertex)

A robust VSK-6A chuck for secure workholding in industrial and workshop lathe applications, designed for repeatable clamping and flexible operation

• 3‑jaw self‑centring mechanism
• Reversible operation for flexible use
• 160 mm nominal diameter for heavy work
• M8 threaded mounting for stable attachment

Faster set‑up and consistent concentricity for production workflows

The 3‑jaw arrangement of this workholding device ensures rapid clamping and repeatable concentricity, which reduces downtime between jobs. The self‑centring mechanism is engineered so that the jaws close uniformly, making it suitable for batch work where consistent runout is essential. The combination of the chuck’s mass and geometry contributes to dampening of vibration; this improves surface finish and prolongs tool life when machining demanding components.

Easy integration with common lathe spindles and fixtures

Mounting is straightforward thanks to the 3xM8 threaded interface, allowing secure attachment to compatible spindle faces or adaptors. The nominal 160 mm diameter provides a broad throat for larger stock, while the compact 95 mm height keeps the centre of gravity low for stable rotation. These measurable characteristics make the component easy to specify in procurement documents and straightforward to compare with alternative clamping systems.

Versatile operation and handling that support shop flexibility

Reversible functionality expands the chuck’s range of applications, enabling both standard and inverted clamping operations without additional tooling. At a mass of 8.3 kg, the chuck delivers the stability expected in heavier turning operations while remaining manageable for routine mounting and removal. Regular inspection and basic maintenance—cleaning of jaw guides and lubrication of the drive mechanism—are sufficient to keep the unit performing reliably over time.

Practical benefits and recommended applications

As a purpose‑built clamping solution, this device is suitable for general turning, facing and light heavy‑duty work where a fast, secure grip is required. The design prioritises throughput: shorter clamping cycles and reliable repeatability translate directly into higher overall productivity. For component batches requiring repeated centring and fast changeovers, the chuck provides a clear operational advantage and can be specified with confidence in engineering documentation.

FAQ

Is this chuck compatible with standard lathe spindles?
Compatibility depends on the spindle face and adaptor; the VSK-6A mounts via a 3xM8 threaded interface and is designed for integration with commonly used adaptors and mounting plates.

What level of concentricity can be expected from the three‑jaw system?
The three‑jaw self‑centring design of the VSK-6A provides repeatable concentricity suitable for general turning and batch production where consistent runout is required.

Can the chuck be used inverted or for back‑mounting?
Yes, the reversible operation allows inverted mounting and alternative clamping orientations without additional specialised tooling.

How heavy is the chuck and what does that imply for handling?
With a mass of 8.3 kg, the chuck offers good damping for improved machining stability; routine handling requires standard lifting precautions and secure fastening to the spindle.

Are there special maintenance requirements?
Basic maintenance—periodic cleaning of jaw guides and light lubrication of moving parts—is recommended to preserve performance of the VSK-6A and extend service life.
