VSK-6 precision chuck — 165 mm, 3,300 kgf clamping force (Vertex)

VSK-6 is a precision clamping chuck designed for secure holding of larger workpieces in lathe and turning centres, suitable for medium-speed machining where stable grip and reproducible positioning are required

• High 3,300 kgf clamping force
• 165 mm diameter for larger workpieces
• Runout accuracy 0.03 mm
• Balanced for 2000 rpm operation

Reliable grip to reduce rework and scrap

The robust construction delivers a consistently high clamping force that secures parts during machining, reducing slippage and the need for rework. With a reinforced body sized at 165 mm, the chuck provides an extended contact area for irregular or larger components. The combination of firm holding power and stable seating helps maintain repeatable tolerances and lowers the incidence of rejected parts in serial production.

Designed for predictable balance and spindle life

Balanced operation is achieved for typical workshop speeds up to 2000 rpm, which minimises vibration and contributes to longer spindle bearings life. The balanced design supports smoother surface finishes and more consistent tool wear, translating into fewer machine interventions. For operations where runout affects process capability, the balanced assembly keeps dynamic behaviour predictable under load.

Precision that is easy to verify

Runout is specified at 0.03 mm, enabling accurate concentricity for turned parts and precise indexing for machining features. This level of accuracy is measurable with standard metrology tools and offers a clear benchmark for quality control. The stated tolerance supports tight production requirements without invoking complex inspection procedures for each setup.

Practical handling and workshop integration

With a workshop weight of 9.5 kg, the chuck is portable enough for manual fitting yet heavy enough to ensure solidity on the spindle. Its form factor and connection interface suit common lathe configurations, allowing straightforward replacement of existing chucks where compatible. The mass and balance contribute positively to vibration damping during cutting operations.

Material handling and application scope

Although specific material recommendations are application-dependent, the chuck’s combination of clamping force and diameter makes it appropriate for a wide range of turning tasks on steel, cast components and aluminium assemblies where secure gripping is essential. The mechanical specification supports use in industrial and subcontracting shops that demand repeatable setup performance.

Maintenance and longevity considerations

The straightforward mechanical design facilitates routine maintenance and inspection, helping to protect the investment over long production runs. Regular checks of runout and jaw seating, combined with correct mounting practice, preserve the chuck’s accuracy and holding capacity, ensuring long-term reliability in daily workshop use.
