Inspection Mandrel MT4 – Ø32×300 mm, runout 0.005 mm (Metav IndustryLine)

The Inspection Mandrel MT4, Ø32×300 mm is a precision test arbor for runout measurement and alignment of machine spindles with a Morse taper fitting.

• Runout accuracy 0.005 mm
• MT4 taper for spindle fitting
• Hardened gauge steel construction
• Total length 430 mm, weight 3.5 kg

Precision that reduces rework and protects tooling

The mandrel delivers a guaranteed runout of 0.005 mm, which provides a reliable reference for concentricity checks and helps to reduce scrap and rework in precision machining. By using a stable reference element with Ø32×300 mm working length and a well-defined taper, inspection cycles become faster and more decisive. The measurable improvement in setup reproducibility translates into lower downtimes and longer tool life, a clear advantage in production and maintenance environments.

Robust build for long-term consistency

Manufactured from hardened gauge steel and produced to DIN 229 standards, the device resists wear and maintains dimensional stability under repeated handling. The heavier mass and total length 430 mm contribute to a stable measuring condition when seated in the spindle, reducing vibration influence during assessment. These construction choices ensure that the reference stays accurate over time, supporting consistent quality control without frequent replacement.

Practical use for alignment and inspection tasks

Designed for runout testing and spindle alignment, the inspection mandrel fits directly into machine spindles with an MT4 taper and serves as a true radial reference for a dial indicator or displacement sensor. The mandrel’s balance and clear cylindrical tolerance allow quick verification of spindle concentricity and the detection of bearing or taper seating faults. Suitable for workshop calibration routines and maintenance checks, this test arbor is a straightforward tool for technicians seeking repeatable alignment results with minimal setup complexity.
