Test Mandrel MT5, 40 x 300 mm — high-precision runout reference for spindle inspection (Metav IndustryLine)

The Test Mandrel MT5, 40 x 300 mm is a purpose-built inspection mandrel for checking and aligning machine spindles with a Morse taper connection, designed for workshop and production metrology tasks where repeatable concentricity is required.

• Runout accuracy 0.005 mm
• Hardened gauge steel construction
• MT5 (Morse taper) mounting for spindles
• Ideal for spindle alignment and testing

Achieve consistent concentricity with measurable benefits

A runout accuracy of 0.005 mm provides a clearly verifiable baseline for spindle condition and concentricity checks. Expressed as a measurable tolerance, this degree of precision reduces rework and scrap by enabling earlier detection of spindle eccentricity. The mandrel serves as a stable reference piece in test setups, giving a quantifiable means to compare spindle behaviour before and after maintenance. Using a calibrated reference such as this mandrel shortens diagnostic cycles and supports quality-control routines with objective data.

Robust construction for repeatable inspections

Manufactured from hardened gauge steel and produced to DIN 229, the mandrel combines dimensional stability with wear resistance so that results remain consistent over many measurement cycles. The 40 mm diameter with a 300 mm functional shank and a total length of 460 mm gives sufficient reach for typical spindle checks while preserving a rigid profile. At approximately 5 kg, the component balances mass for vibration damping during rotation with manageable handling for workshop personnel. This construction supports repeatable measurements and reduces uncertainty caused by instrument deformation.

Practical compatibility and workshop use

Equipped with an MT5 (Morse taper) mounting, the mandrel integrates directly into conventional spindle sockets and test fixtures used in machining centres and inspection benches. The simple seating principle allows rapid installation and removal without auxiliary tooling, streamlining inspection workflows. As a purpose-made inspection gauge it is suited to both periodic maintenance checks and acceptance testing after spindle rebuilds. The design focuses on usability and traceable results, helping teams maintain production uptime while documenting spindle condition objectively.
