Metav IndustryLine Cylindrical Test Mandrel M318.910 — Ø20 x 200 mm, 0.005 mm runout accuracy

Metav IndustryLine Cylindrical Test Mandrel M318.910 is a precision gauge designed for runout verification and fixture checking in workshop and quality‑control environments

• Cylindrical test mandrel Ø20 x 200 mm
• Runout accuracy 0.005 mm
• Both ends centred for stable mounting
• Hardened gauge steel, robust and wear‑resistant

Built for measurable precision in routine inspection

The mandrel delivers a quantifiable advantage where repeatability matters: 0.005 mm runout accuracy ensures that spindle, chuck and component alignment tests provide consistent, comparable results. Manufactured from hardened gauge steel, the shaft resists wear across repeated setups and maintains its geometry over time. This combination of material and tolerance reduces rework and supports quick decision‑making on assembly lines and inspection benches, helping to improve overall process efficiency.

Stable handling and simple integration into existing workflows

With both ends centred, the mandrel offers stable seating in chucks or fixture bores, which minimises eccentricity introduced by the support itself. The cylindrical design and standard Ø20 x 200 mm dimensions permit straightforward use with common holding devices and measuring stands. The tool is suitable for checking runout with calipers and other shop instruments used in metrology routines, enabling technicians to perform checks without complex fixturing or extensive retraining.

Material choice and practical benefits for daily use

Constructed from hardened gauge steel, the mandrel combines surface hardness with dimensional stability, which translates into a long service life under normal workshop conditions. The modest mass (approx. 1 kg) gives a balance between rigidity and manageability during mounting and inspection. By integrating this precision arbor into routine checks, workshops gain a durable reference that supports faster acceptance testing and fewer measurement disputes.

FAQ

What is the primary use of this mandrel?
The mandrel is intended for runout and roundness checks; the Metav IndustryLine test mandrel M318.910 serves as a precision reference for spindle and chuck verification.

Can the mandrel be used with standard calipers and measuring stands?
Yes. The Ø20 x 200 mm geometry and centred ends allow the mandrel to be mounted and measured using common calipers and standard measuring fixtures.

How does the 0.005 mm specification affect inspection routines?
A declared runout accuracy of 0.005 mm provides a clear tolerance boundary for acceptance tests, improving decision speed in quality control processes when using the mandrel as a reference.

Is the mandrel suitable for continuous workshop use?
The hardened gauge steel construction is chosen for durability and dimensional stability, making the mandrel well suited for regular use in industrial inspection settings.

Does the mandrel require special handling or storage?
Normal care for precision gauges is recommended: protect contact surfaces from scratches and store in a dry environment to preserve surface condition and accuracy.

Are centring features present on both ends necessary?
Yes. Centred ends reduce mounting‑induced eccentricity and ensure a stable reference when used in chucks or support bores during runout tests.
