VFR-12 Clamping Ring – 316 mm diameter, for soft jaw inserts (Vertex)

The VFR-12 is a clamping ring designed for use with soft jaw inserts on 12-inch chucks, intended to secure workpieces reliably in lathe and turning applications.

• 316 mm diameter for large workpieces
• Compatible with 12-inch soft jaw inserts
• Solid construction, approx 5 kg weight
• Ensures repeatable, secure workholding

Precise compatibility that reduces set-up uncertainty

The clamping component is engineered to mate precisely with soft jaw inserts, ensuring defined seating and alignment on the chuck. With a 316 mm diameter the ring accommodates larger workpieces while keeping clamping forces centralised; this leads to fewer adjustments during set-up and a lower risk of runout. The described geometry and interface are suitable for typical turning operations where repeatability and positional accuracy are required, and the design purpose is to provide consistent contact for insertion and removal of soft jaws.

Stable mass and form for reliable machining results

A 5 kg mass contributes to mechanical stability without adding unnecessary bulk, so vibration is reduced and holding power remains consistent across cycles. The result is secure workholding that supports steady feeds and surface finishes during machining. Because the component is intended for integration with standard 12-inch jaw systems, changeovers are predictable and can be incorporated into existing workflows with minimal modification. The combination of mass, diameter and mating interface helps maintain concentricity and reduces the need for repeated corrections.

Practical use and procurement guidance for machine shops

The ring is suited to workshops that require efficient clamping for medium to large turning tasks and want a straightforward solution for soft jaw workflows. Manufactured by Vertex, the component is intended as a robust, purpose-built accessory for established chuck systems; traceability is supported by the SKU and GTIN for inventory control. For users assessing fitment, check chuck jaw type and mounting specifications to confirm compatibility. Technical queries regarding integration or dimensional verification can be addressed by Metav Werkzeuge’s advisors prior to purchase.
