3-jaw lathe chuck VNBK-10 — self-centring, extra-flat, Ø315 mm (Vertex)

The 3-jaw lathe chuck VNBK-10 is a self-centring, extra-flat clamping solution designed for turning and facing tasks on medium-sized lathes, offering a compact profile for improved tool access and stable workholding.

• Self-centring, extra-flat design
• Diameter 315 mm for medium workpieces
• Clamping force 3150 kgf for secure hold
• Robust construction, approx. 30.5 kg

Faster set-up through precise centring

The self-centring mechanism ensures rapid and consistent alignment of round and hexagonal components, which reduces adjustment time during batch production. Improved concentricity minimises run-out and supports repeatable tolerances, making the chuck well suited to tasks where reliable positional accuracy is essential. The result is fewer manual interventions during loading and shorter overall cycle times, supporting efficient throughput on the shop floor.

Secure clamping for heavier cuts and steady machining

A rated clamping force of 3150 kgf provides a high holding capacity that helps resist pull-out under cutting loads, allowing more aggressive feed rates and stable material removal. Combined with the low-profile mounting, vibration is reduced during heavy-facing or roughing passes, which leads to improved surface finishes and extended tool life. This performance characteristic directly contributes to predictable process outcomes and reduced scrap rates.

Compact design that improves accessibility and tool clearance

The extra-flat profile reduces spindle overhang and brings the workpiece closer to the machine centre, enhancing rigidity and enabling shorter tooling setups. Closer proximity to the spindle bore simplifies tool paths and offers improved access for turning and facing operations on medium-sized components up to Ø315 mm. The compact form factor also aids in operations where space around the chuck is constrained, supporting ergonomic handling and more flexible fixturing.

Durable build for continuous production use

Weighing around 30.5 kg, the chuck’s mass reflects a robust construction that resists deformation under load and maintains clamping consistency over repeated cycles. Manufactured by Vertex, the product is intended for workshop environments where long-term reliability and predictable performance are required. Routine inspection of jaws and drive components will preserve clamping integrity and contribute to safe, uninterrupted production.
