Vertex VSK-12 310 mm chuck — 5,700 kgf clamping force, 0.03 mm accuracy

The Vertex VSK-12 is a precision chuck designed for demanding workholding in turning and heavy-duty machining applications.

• High clamping force 5,700 kgf
• 310 mm gripping diameter for large parts
• Accuracy 0.03 mm for consistent concentricity
• Rated top speed 1,800 rpm

Engineered for secure heavy-duty clamping

The workholding device delivers a clamping force of 5,700 kgf, which translates into reliable retention of heavy or high-torque components during machining. A larger 310 mm diameter increases the usable clamping surface, enabling secure handling of sizeable workpieces without resorting to complex fixtures. By concentrating on measurable performance, the chuck reduces the likelihood of slippage and vibration, supporting uninterrupted production cycles and improving overall throughput.

Precision that lowers rejects and machining time

With a stated accuracy of 0.03 mm, the chuck ensures close concentricity between the spindle axis and the clamped part, which directly reduces setup time and the need for corrective finishing. The specified maximum speed of 1,800 rpm allows safe operation within common turning ranges while maintaining the declared tolerance. These characteristics make the device appropriate where dimensional consistency matters, converting technical performance into tangible cost-saving benefits through fewer rejects and less downstream grinding or rework.

Workshop integration and operational reliability

Weighing 39.3 kg, the chuck balances mass for stability with practical handling in a machine-shop environment. The component’s design supports straightforward installation on compatible spindles and stable operation under load, contributing to predictable cycle times.

FAQ

What materials is this chuck suitable for clamping?
The Vertex VSK-12 chuck is a general-purpose workholding device intended for a wide range of turning operations and is commonly used with ferrous and non-ferrous components within the machine’s and tooling system’s limits.

How does the stated accuracy affect finished parts?
An accuracy of 0.03 mm with the VSK-12 minimises runout, resulting in improved concentricity and reduced need for secondary machining, which helps maintain consistent part tolerances.

Can the chuck run at high spindle speeds?
The VSK-12 is rated to a maximum of 1,800 rpm; this specification should be matched with the machine and tooling to ensure safe, vibration-free operation.

What does the clamping force value indicate in practice?
A clamping force of 5,700 kgf indicates the holding strength under normal operating conditions, supporting the secure retention of larger or heavier workpieces during machining cycles.

Is the chuck compatible with standard lathe spindles?
Compatibility depends on the spindle interface; the VSK-12 is designed for common industrial machine arrangements, but spindle mounting details should be confirmed against the machine’s specification.
