Vertex VMJ-6 chuck — self‑centring 4‑jaw with 900 kgf clamping force

A Vertex VMJ-6 chuck engineered for precise, repeatable clamping of square workpieces and general machining tasks in workshop environments.

• Self‑centring 4‑jaw design
• High clamping force 900 kgf
• Compact footprint 165x215x96mm
• Accuracy 0.03

Secure clamping that speeds up set‑up and saves cycles

The self‑centring, four‑jaw mechanism delivers reliable concentricity with fast engagement, reducing the time required for repeated set‑ups. The combination of a robust jaw configuration and a rated clamping force of 900 kgf offers a clear operational advantage: workpieces stay stable under load, which minimises rework and improves throughput. For operations focused on repeatability, this clamping solution provides measurable benefits in cycle time and process reliability.

Tight tolerances for consistent part quality

An accuracy figure of 0.03 indicates a high degree of concentricity, allowing finer tolerances to be maintained during turning or machining operations. A stable mass of 13.5 kg helps dampen vibration, contributing to surface finish and dimensional stability. For teams that validate parts against defined tolerances, the precision characteristics of this chuck support predictable outcomes and reduce inspection exceptions.

Compact design to integrate into constrained workspaces

With external dimensions of 165x215x96mm, the chuck occupies a modest footprint while still delivering performance suited to many workshop set‑ups. The square‑jaw option increases flexibility for clamping non‑round components without additional fixtures. This compactness supports efficient use of machine table space and simplifies handling during tool changes, aiding leaner workflows on the shop floor.

Practical features and workshop compatibility

The unit’s four‑jaw, self‑centring concept allows a balance between grip versatility and operational simplicity. The design reduces the number of adjustments needed for common jobs and works well where a mix of square and round parts are processed. Clear marking of SKU and traceability simplify stock management and ensure correct replacement parts and accessories are ordered when required.
