VSI-3 Indexing Head by Vertex — 25 mm mounting bore, 1° indexing

The VSI-3 is a compact parts indexing head designed for precise angular positioning in workshops and small production cells, suitable for fixturing, measurement and light machining tasks.

• 1° indexing increments
• 25 mm mounting bore
• Compact 120 x 117 x 116 mm footprint
• Robust 7.5 kg construction

Accurate angular positioning for repeatable setups

The VSI-3 offers 1° indexing, a mechanical step size that enables reliable division of a full rotation into repeatable angular positions. This degree step is displayed as a clear graduations value, which simplifies the selection of common indexing angles without digital aids. The result is improved repeatability during batch operations and reduced time spent on alignment checks. For operations that demand consistent angular locations — such as drilling patterns, inspection stages or light reaming — the precise step increments translate directly into fewer rejects and more predictable throughput.

Compact footprint that eases integration into fixtures

With external dimensions of 120 x 117 x 116 mm and a standard 25 mm mounting bore, the unit is purposely compact to fit tight fixture layouts and small machine tables. The small envelope supports efficient use of bench or machine table space while enabling straightforward mechanical coupling to existing spindles or adapters. This compactness reduces the need for complex fixturing and helps maintain clear access to the workpiece, making it suitable for both prototyping benches and limited-footprint production cells where space economy matters.

Solid mass and construction for stable operation

At 7.5 kg, the indexing head provides a substantial, vibration-damping mass that contributes to stable positioning under machining light loads. The noticeable mass and robust design reduce micro-movements during short machining cycles and measurement routines, increasing the quality of each indexed operation. The construction supports frequent cycle usage common in workshop environments, and the mechanical simplicity means maintenance is limited to routine checks and lubrication rather than frequent part replacement.

Straightforward handling for faster cycle times

The mechanical indexing principle of this head keeps operation intuitive and fast: once mounted via the 25 mm bore, indexing steps are set and locked with minimal tooling. This lowers setup complexity and shortens the time from first part to steady production. The device is particularly suitable where controlled angular positioning is required without the overhead of fully motorised rotary tables — a pragmatic balance of precision and operational speed that fits many small- to medium-scale machining and inspection workflows.
