Test mandrel MT6 50×500 mm — 0.005 mm runout accuracy (Metav IndustryLine)

The Test mandrel MT6 50×500 mm is a precision gauge for runout inspection and alignment of machine spindles where Morse taper mounting is used.

• 0.005 mm runout accuracy
• Hardened gauge-steel construction
• Conforms to DIN 229 specification
• Suitable for spindle alignment with MT6

Precision that secures repeatable spindle checks

The mandrel offers a runout accuracy of 0.005 mm, a level of precision that reduces uncertainty in spindle concentricity measurements and supports reliable quality control in turning and grinding operations. Measured deviations at this level translate directly into fewer scrap parts and less machine rework; the tight tolerance is particularly relevant when balancing rotors or verifying spindle bearings. The concept of runout describes the deviation of a rotating axis from its true geometry, and a low figure here ensures that subsequent machining runs start from a consistent reference.

Durable construction for workshop demands

Manufactured from hardened gauge steel and produced to DIN 229, the mandrel is built to withstand repeated mounting cycles and the mechanical stresses of alignment work. Hardened gauge steel provides a stable contact surface that resists wear, ensuring measurements remain reliable over time. Where reference tools are handled frequently, material hardness and dimensional stability are decisive for maintaining calibration intervals and reducing lifetime maintenance costs. The adherence to an established standard offers clear comparability and confidence in cross-check situations.

Practical dimensions for alignment and inspection

With a functional diameter of Ø50 mm and a gauge length of 500 mm (overall length 715 mm), the mandrel balances reach and rigidity for many workshop tasks. The substantial mass—approximately 12 kg—adds rotational stability during checks but also requires suitable handling precautions or lifting aids for safe use. The MT6 taper provides a conventional interface for many machine spindles and tailstocks, enabling straightforward installation without special adaptors in most setups. These proportions make the device well suited for aligning medium-length spindles, verifying chuck runout and checking mounted tooling.

Supportive supply chain and quality assurance

FAQ

What level of runout can be expected with this mandrel?
The mandrel achieves a runout accuracy of 0.005 mm, a specification that makes the Metav IndustryLine MT6 test mandrel (SKU M318.936) suitable for high-precision spindle checks.

Which machines is the mandrel compatible with?
Compatibility is provided via the MT6 Morse taper interface; the gauge mandrel is intended for spindles and tailstocks accepting an MT6 taper and for standard inspection setups.

Is the material suitable for heavy workshop use?
Yes — the tool is made from hardened gauge steel and produced to DIN 229, giving it wear resistance and dimensional stability for frequent inspection tasks.

How should the mandrel be handled given its weight?
At around 12 kg, the mandrel offers stability during measurement but requires appropriate handling or lifting equipment to avoid strain and ensure safe positioning in the spindle or fixture.

Can this mandrel be used for balancing rotors or verifying chucks?
The precise runout and rigid construction make the device well suited for tasks such as rotor balancing checks and chuck runout verification, where a stable reference is required.
