Control mandrel SK30-D32-250L — high-precision spindle runout master with Ø32 mm and 250 mm length

Control mandrel SK30-D32-250L designed for runout testing and aligning machine spindles with SK30 mounting; robust gauge-steel construction for workshop and inspection use.

• Roundness accuracy 0.002 mm
• SK30 taper for spindle alignment
• Hardened gauge steel, HRC 58
• Complies with DIN ISO 7388-1

Precision that reduces rework and saves machine time

The solid, hardened gauge steel body with a hardness of HRC 58 provides a stable reference that resists wear during repetitive checks. With a roundness accuracy of 0.002 mm, the mandrel is suitable as a go/no-go reference for spindle runout diagnostics and helps to cut corrective maintenance time. The cylindrical form (Ø32 mm, length 250 mm) and the controlled surface finish reduce measurement uncertainty and enable consistent alignment across successive setups.

Designed for practical workshop integration and efficient inspection

Equipped with an SK30 taper, this mandrel slots directly into standard SK30 spindles, allowing quick checks without adaptors. The combination of taper compatibility and the specified cylindricity (<0.003) enables straightforward positioning for both manual and machine‑based inspections. The result is a pragmatic tool that integrates into existing workflows to improve machine uptime and minimise scrap through faster, more reliable runout verification.

Traceable standards and measurable results

Compliance with DIN ISO 7388-1 gives a clear normative basis for acceptance checks and internal quality procedures. Numeric indicators such as the 0.002 mm roundness and the cylindricity specification support objective decision-making in quality control: whether to accept a spindle, adjust bearings or schedule maintenance. The mandrel’s substantial mass (approx. 8 kg) also contributes to stable seating in the spindle, improving repeatability of readings.

Built for workshop durability and repeat inspections

The choice of hardened gauge steel and conservative geometry prioritises longevity and low life‑cycle cost. The tool’s robustness means fewer replacements and a reliable reference for alignment jobs in metalworking shops and service departments. The design keeps handling straightforward while ensuring the precision needed for demanding tolerance windows, making it a dependable element in routine spindle maintenance and precision checks.
