Test mandrel HSK‑E50‑D32‑L250 — runout test mandrel, <0.003 mm

The Test mandrel HSK‑E50‑D32‑L250 is a precision gage designed for runout verification and the accurate alignment of machine spindles in workshop and production environments

• HSK‑E50 interface for standard spindle mounts
• Runout <0.003 mm for high-precision verification
• Hardened gauge steel, HRC 58 for wear resistance
• Conforms to ISO 12164/DIN 69893 standards

Precision that reduces rework and machine downtime

This test mandrel delivers a measured runout accuracy of <0.003 mm, enabling reliable assessment of spindle concentricity and bearing condition before costly setups or production runs. The tight tolerance translates directly into lower scrap rates and fewer machine stoppages because irregularities are detected early. The HSK‑E50 interface and the mandrel’s defined shank adaptation permit simple, repeatable mounting in standard spindle tapers, so measurement results are comparable across successive checks. When process control depends on concentricity, the combination of interface standardisation and verified runout performance provides a rational basis for traceable quality decisions.

Robust build for repeatable workshop performance

Constructed from hardened gauge steel and tempered to HRC 58, the arbor is engineered for long service life under routine handling and inspection cycles. The geometry and mass distribution have been optimised for stable seating in the spindle, which supports consistent readings during turntable or indicator checks. At approximately 3 kg, the mandrel is weighty enough to remain stable during measurement yet manageable for single‑person handling in the inspection bay. The durable surface and heat treatment reduce wear and preserve the critical seating surfaces, so calibration intervals can be planned with confidence and the tool continues to perform as intended.

Conformity and practical application in metrology workflows

Manufactured to ISO 12164/DIN 69893, this gage fits into formal inspection protocols and supports quality documentation. Use cases include runout testing, spindle alignment, and comparative checks of chucking or toolholding systems; the mandrel is intended as a reference artefact for aligning spindles and verifying machine accuracy. The gauge steel material and standardised interface ensure compatibility with existing fixtures and measuring instruments. For operations seeking measurable improvements in set‑up reliability and process control, the mandrel provides a technically verifiable solution that integrates with established metrology routines.
