VKC-50 Independent four-jaw chuck – Ø 1250 mm, 150 rpm – Vertex

The VKC-50 independent four-jaw chuck is a heavy-duty workholding solution designed for large-diameter turning on industrial lathes

• Independent four-jaw design for exact centring
• Large Ø 1250 mm gripping capacity
• Rated speed 150 rpm for heavy work
• Robust build, approx 905 kg mass

High-capacity workholding for large components

The VKC-50 delivers a Ø 1250 mm clamping range that enables secure handling of substantial parts. Its mass of 905 kg contributes to inherent stability during turning, reducing vibration and improving surface finish; this stability is particularly important when machining large diameters where rigidity determines process reliability. The result is a workholding device that supports continuous production runs in heavy industries by providing the structural basis for repeatable machining operations.

Accurate, independent clamping for irregular and complex parts

Thanks to its independent four-jaw concept, each jaw can be set separately, which enables precise centring of asymmetrical or irregular workpieces. This flexibility reduces the need for special fixtures and simplifies the setup of one-off or batch runs requiring individual jaw adjustment. The independent jaw control supports high precision clamping, making the chuck suitable for tasks where concentricity and part geometry demand careful alignment rather than relying on a single fixed centre point.

Engineered for reliable operation on industrial lathes

Operational parameters such as the rated 150 rpm indicate suitability for heavy turning rather than high-speed applications, aligning the chuck with slow, high-torque machining operations. The T-nut 8-M20 mounting arrangement offers a standardised interface for secure attachment to a variety of spindle faces or adaptors, ensuring compatibility within robust turning setups. The combination of deliberate speed rating and substantial mass optimises torque transfer and reduces centrifugal effects, supporting safe, stable use in demanding environments.

Workshop integration and productivity benefits

In a production context, the chuck’s capacity and independent jaw control help to cut setup time for non-standard parts and to reduce reliance on specialised clamping fixtures, contributing to improved workflow efficiency. Specifying this workholding element supports a pragmatic approach to heavy machining: the robust construction minimises unplanned downtime and the standardised mounting eases integration into existing machine fleets. For buyers seeking a dependable partner in precision, Metav’s supply chain and quality filter for the European market ensure consistent delivery and technical guidance.

FAQ

What maximum workpiece diameter can be clamped with this chuck?
The VKC-50 provides a clamping capacity of 1250 mm, suitable for large-diameter components used in heavy turning operations.

Is the chuck suitable for irregular or non-cylindrical parts?
Yes; the independent jaw arrangement of the Vertex VKC-50 allows each jaw to be adjusted separately, enabling precise centring of asymmetrical or irregular workpieces.

What is the recommended operating speed for this workholding solution?
The VKC-50 is rated for 150 rpm, which matches heavy-duty, high-torque turning processes rather than high-speed machining.

How is the chuck mounted to the machine spindle?
Mounting is via a T-nut 8-M20 arrangement, providing a secure and standardised interface for attachment to compatible spindle faces or adaptors.

For which workshop applications is this chuck intended?
This Vertex independent four-jaw chuck is intended for industrial lathe applications where large diameters, rigid clamping and precise jaw adjustment are required, such as heavy fabrication, rotor turning and large-part servicing.
