Clamping chuck VSK-20 — 500 mm diameter, 0.03 mm repeatability (Vertex)

Clamping chuck VSK-20 is a heavy‑duty clamping unit designed for large workpieces in machining centres and heavy lathes, offering precise axial repeatability at controlled spindle speeds.

• 500 mm nominal diameter
• Repeatability 0.03 mm
• Rated speed 1,000 rpm
• Mass 145.5 kg for stable clamping

Precise positioning for large components

The 500 mm nominal diameter combined with a repeatability of 0.03 mm ensures consistent positioning of sizeable workpieces, which reduces setup deviation and rework. In practice, repeatability refers to the chuck’s ability to return a clamped part to the same position after remounting; this metric is essential when batches require interchangeability or when off‑line inspection relies on reproducible clamping. The robust design and measurable accuracy support tight tolerance processes, helping maintain downstream quality and throughput.

Stable operation and reduced vibration at machining speed

A rated spindle capability of 1,000 rpm together with a mass of 145.5 kg delivers inherent damping and rotational stability, which lowers chatter risk during roughing and semi‑finishing. The clamping unit’s inertia contributes to smoother cuts and a better surface finish on demanding materials. For production planning, the controlled speed rating clarifies the operational envelope; pairing the chuck with appropriately balanced workpieces and matched tooling minimises imbalance and maximises machining efficiency.

FAQ

How accurate is the clamping when remounting components?
The clamping chuck VSK-20 delivers a repeatability of 0.03 mm, which defines its capacity to return a remounted workpiece to the same axial position for consistent batch quality.

What maximum rotational speed is suitable for this chuck?
The unit is specified for operation up to 1,000 rpm, aligning the clamping performance with stable, heavy‑workpiece machining.

Is the VSK-20 suitable for large turning centres?
Yes, the VSK-20 is designed for large workpieces and heavy‑duty lathes or machining centres where a 500 mm nominal diameter and substantial mass support stable clamping.

How does the chuck’s mass affect machining results?
A mass of 145.5 kg increases rotational inertia and damping, reducing vibration and supporting improved surface finish and tool life during heavy cutting operations.

What identifiers are useful when ordering spare parts or matching fixtures?
Use the SKU VSK-20 and GTIN 4061905096105 for precise ordering and component matching.
