Inspection mandrel M318.911 — cylindrical test mandrel, Ø30×300 mm, runout accuracy 0.005 mm (Metav IndustryLine)

An Inspection mandrel M318.911 designed for high-precision runout checks in component inspection and assembly fixtures, offering a compact diameter with extended length for versatile gauging tasks across production and quality control environments.

• Cylindrical inspection mandrel Ø30×300 mm
• Runout accuracy 0.005 mm
• Hardened gauge steel construction
• Both ends centred for secure mounting

Consistent runout verification for reliable quality control

The mandrel delivers a measurable runout accuracy of 0.005 mm, which translates into tighter process control and fewer escaped defects during assembly and finishing. By using a fixed-diameter, straight shaft the operator benefits from reduced measurement scatter and improved repeatability compared with ad‑hoc fixturing. Where concentricity and spindle alignment affect downstream performance, this tool enables quick go/no‑go checks and objective documentation of part condition, reducing rework and protecting downstream processes.

Robust materials and centred mounting for stable measurements

Manufactured from hardened gauge steel, the mandrel combines stiffness with wear resistance to preserve geometry over repeated use. The shaft’s Ø30 mm section and 300 mm overall length maintain adequate rigidity for medium-length components while the specification of both ends centred ensures reproducible mounting in chucks or fixtures. The resulting stability means fewer positional deviations during rotation, allowing measurement instruments and dial indicators to record truer values with less need for operator compensation.

Practical integration into inspection workflows

Designed as a straightforward go‑to tool for runout inspection, the mandrel fits into existing benches and inspection routines without complex setup. Its solid construction and clear dimensional spec simplify traceability in quality records and make it suitable for routine checks in machine shops, toolrooms and incoming inspection. The compact footprint eases handling between fixtures; the clear numeric tolerance facilitates immediate decision making in first‑article inspections or batch sampling.
