Consistent, measurable accuracy for inspection work

A reference sphere with a diameter of 19 mm and a stated accuracy of 0.003 mm (3 µm) supplies a clear, quantifiable basis for decisions in quality control. The declared diameter tolerance of 0.00008 mm supports fine comparison tasks where even minute deviations matter; this level of specification is useful when verifying the performance of gauges, testing fixture repeatability or checking machine-centre calibration. By relying on objectively stated numbers rather than subjective judgement, production processes can be validated and traced with confidence. The numerical data therefore directly contributes to fewer reworks and more predictable inspection outcomes.

Robust material and geometry for repeatable contact

Constructed from hardened chrome steel and specified with hardness >HRC 62, the spheres are designed to withstand repeated contact without rapid wear, maintaining geometry across repeated cycles. A low surface roughness supports stable seating against gauge contacts and minimises measurement scatter; consistency of the contact surface helps to reduce variation introduced by surface irregularities. Supplied as a matched pair, the two spheres are closely matched in diameter and finish, enabling comparative checks and quick functional tests between fixtures or measuring devices. The paired format simplifies in‑house verification workflows where a quick cross‑check is required before a production run.

Suitable for workshop inspection and calibration labs

These reference spheres fit well into standard workshop and laboratory routines where compact, high-precision artefacts are required for setup and verification. Their modest weight and compact size make them easy to handle while still providing a stable reference for small‑part gauging, fixture alignment and comparator work. The product supports rational decision‑making: measurable specifications, durable construction, and a matched delivery format reduce ambiguity during routine checks. Should additional information be required about compatibility with specific gauge systems or inspection procedures, Metav’s Emmerich‑based specialists provide concise technical support and can supply the matched set ready for immediate use.

FAQ

What measurement accuracy can be expected from these gauge balls?
The gauge ball pair M318.429 from Metav IndustryLine is specified with an accuracy of 0.003 mm, making the set suitable for sub-millimetre reference tasks and fine comparative checks in inspection environments.

Are the spheres delivered as a matched set?
Yes, the product is supplied as a matched set of two spheres (SKU M318.429), enabling direct comparison and fast functional verification between fixtures or measuring devices.

What material and hardness are the reference spheres made of?
The spheres are manufactured from hardened chrome steel with a hardness greater than HRC 62, which supports long-term wear resistance and stable contact geometry.

Can these gauge balls be used for fixture and gauge checks in a production workshop?
The matched pair and the defined tolerance make them well suited for workshop fixture checks, comparator setups and routine instrument verification where compact, durable reference items are required.
