Inspection mandrel MK4, 32×300 mm — Runout accuracy 0.005 mm (Metav IndustryLine)

The Inspection mandrel MK4, 32×300 mm provides a stable reference for runout and concentricity checks, designed for spindle alignment and precision testing in machine shops and inspection benches.

• Runout accuracy 0.005 mm
• MK4 taper for spindle compatibility
• Hardened gauge steel construction
• Compliant with DIN 229

Precision that reduces rework and increases throughput

The mandrel delivers a guaranteed runout of 0.005 mm, making it a reliable reference for repeatable measurements and alignment tasks. When used as the master datum in inspection procedures, the low runout minimises adjustment cycles and lowers the risk of rejected parts. The mandrel’s dimensional stability supports consistent readings with dial indicators and electronic measuring systems, shortening setup times and improving overall production efficiency without compromising measurement integrity.

Built for stability and long service life

Manufactured from hardened gauge steel and produced to DIN 229, the shaft resists wear and maintains its geometry under regular use. The robust material selection provides a durable contact surface for precision instruments and reduces thermal distortion during routine shop-floor conditions. This construction ensures the mandrel remains a reliable reference over time, which translates into fewer replacements and lower life‑cycle costs for measurement equipment.

Designed for shop-floor integration and compatibility

With an MK4 taper and a shaft dimension of 32×300 mm, the mandrel fits standard interfaces used for spindle testing and alignment. The geometry suits runout testing and concentricity verification on spindles and chucks, enabling quick integration into existing inspection workflows. Its compatibility simplifies calibration routines and supports a methodical approach to spindle set-up, improving machine availability and contributing to predictable production outcomes.

Practical handling and repeatable measurement

The mandrel’s total length of 430 mm and a shaft usable length of 300 mm provide access to deeper spindle seats while maintaining rigidity. At approximately 3.5 kg, the component is manageable for single-person handling in routine checks yet heavy enough to remain vibration‑resistant during measurement. The balanced design supports stable readings across the working length, helping technicians achieve consistent results with both mechanical and electronic indicators.
