Test mandrel MK3 — runout accuracy 0.005 mm, Ø25 × 250 mm (Metav IndustryLine)

The Test mandrel MK3 is a precision gauge intended for runout testing and alignment of machine spindles with an MK3 taper, suited to quality control in toolrooms and production workshops.

• Extremely low runout 0.005 mm
• Hardened gauge steel construction
• MK3 Morse taper mounting
• Conforms to DIN 229 standard

Minimise rework with industrial-grade runout control

A stable reference shaft with runout accuracy 0.005 mm reduces measurement uncertainty and shortens inspection cycles. The mandrel serves as a repeatable datum for concentricity checks and balancing tasks, meaning faults are identified earlier in the process and costly rework is avoided. In practice, the low radial deviation improves detection of spindle and fixture errors, so quality assurance teams can document true machine condition rather than artefacts of the test setup. The combination of compact diameter and defined usable length provides a clear, measurable standard that integrates easily with existing inspection routines.

Robust materials for reliable shop-floor performance

Manufactured from hardened gauge steel and produced to DIN 229, the component offers mechanical stiffness that resists wear and deformation during routine handling. The hardened finish sustains dimensional stability across repeated insertions into the spindle taper, which prolongs service life and preserves the calibrated condition of the reference surface. The MK3 taper provides a common, secure interface with conventional spindles and adapters, reducing the need for bespoke fixtures. This robustness translates into fewer interruptions for repair and less frequent replacement, improving uptime on critical machines.

Faster alignment and verifiable measurements

With a usable shaft of Ø25 × 250 mm and a total length suited to the task, the mandrel balances reach and handling convenience. The weight and geometry aid stable seating in the spindle, supporting faster rough alignment followed by fine adjustment using dial indicators or measuring probes. Using a single, well-specified mandrel for both concentricity checks and alignment tasks streamlines procedures: one tool for runout measurement, balancing setup and verification of collets or chucks. Documentation of results becomes straightforward, supporting traceable quality workflows and supplier audits.

Workshop-ready supply and brand assurance

Sourced via Metav IndustryLine, this test mandrel benefits from a supplier approach that emphasises accessibility and consistent quality across a broad catalogue. Metav’s handling in Emmerich acts as a quality filter for the European market, offering secure logistics and product availability so that calibration programmes and maintenance schedules remain predictable. For organisations seeking dependable metrology tools without excessive supplier overhead, the combination of certified production standards and Metav’s distribution network supports both procurement simplicity and long-term process reliability.

FAQ

What level of runout can be expected from this mandrel?
The mandrel delivers a runout accuracy of 0.005 mm as supplied; this specification applies to the Test mandrel MK3 (Metav IndustryLine, SKU M318.933).

Is the mandrel compatible with standard spindle tapers?
Yes, the tool is supplied with an MK3 (Morse taper 3) interface, allowing secure seating in spindles and adapters designed for that taper.

Which material is used for the shaft and why does it matter?
The shaft is made from hardened gauge steel, chosen for dimensional stability and wear resistance so that the reference surface remains reliable under repeated use.

Can this mandrel be used for both concentricity checks and alignment tasks?
Yes, the Ø25 × 250 mm usable shaft and the precise runout make it suitable for concentricity measurement, balancing preparations and spindle alignment operations.
