Micrometer calibration for manufacturing

Machine shops and fabricators across Perth rely on micrometers for the dimensions that decide whether a part ships. When a customer PPAP or first-article inspection references a micrometer reading, the calibration certificate for that micrometer is part of the evidence pack.

A micrometer is the instrument a machinist reaches for when the tolerance is tight, so its calibration record is the one an auditor is most likely to ask about. AmpTech calibrates external, internal and depth micrometers in our Caversham lab against traceable gauge blocks, checking readings at points across the full range.

Interval in manufacturing

12 months (6 months for final inspection)

ISO 9001; customer quality requirements

Setting the interval

Twelve months is standard. Micrometers used for final inspection or on close-tolerance work are commonly kept on a 6-month interval, with a setting-standard check between calibrations.

What the calibration covers

Reading against gauge blocks at points across the range, chosen to exercise the full rotation of the thimble
Zero setting, and the setting standard supplied with larger micrometers
Anvil and spindle face condition and contact
Ratchet or friction thimble operation, which affects repeatability
Rod extensions on depth micrometers, each checked individually

What your certificate records

The certificate format manufacturing procurement and audit teams ask for: the equipment under test, its serial number, the reference instruments used, as-found and as-left readings, environmental conditions and a traceability statement, plus the micrometer-specific items below.

As-found and as-left readings at each gauge-block length checked
Zero and setting-standard results
Measuring-face condition observations
Gauge blocks and reference standards used, with traceability

How manufacturing clients get micrometers to us

Calibration is performed in our Caversham lab — not on site. We collect from and deliver back to manufacturing workshops and offices across Perth, and instruments from regional sites come by freight or via your Perth base.

Canning Vale and Bibra Lake manufacturing precincts
Welshpool and Kewdale fabrication and assembly workshops
Malaga light industrial and trade workshops
Osborne Park commercial and QC laboratories

Working with manufacturing procurement

We work with quality and production teams to align calibration intervals with your control plan, supply certificates that map directly to your gauge register, and schedule recall reminders so nothing falls out of cal during a production run.

FAQ

Micrometer calibration for manufacturing FAQs

Can you match the certificate to our gauge numbers?

Yes. Tell us your asset or gauge numbers when you book and each certificate and the register will carry them, so the records drop straight into your gauge control system.

Should I send the setting standard with my micrometer?

Yes. The setting standard is checked and reported with the micrometer, so you know both halves of the pair are correct.

Do you calibrate micrometer sets?

Yes. Sets are calibrated as individual instruments, each with its own certificate, and returned together with a register covering the set.
