Common Questions
If a question below is not covered, it can be answered directly — see the contact page.
What standards is CMM calibration performed under?
Calibration is performed under ISO/IEC 17025:2017. Certificates are issued under the performing laboratory's accredited scope and state the reference standards and uncertainty used.
Can a CMM be calibrated on-site instead of shipped out?
Bridge and gantry machines are usually calibrated on-site because of their size. Portable arms and small gauging can often be sent to a laboratory instead.
What happens if a CMM fails calibration?
Where the machine falls outside tolerance, an as-found report documents the condition. Repair, adjustment or part retirement is then quoted separately before any further work.
What appears on a calibration certificate?
The certificate states the reference standards used, the reported measurement uncertainty, as-found and as-left data, and the date of measurement.
How often should a CMM be recalibrated?
Interval depends on use, environment and internal quality system requirements. A documented interval review suits most fleets better than one fixed default applied to every machine.
Can part programs be written during a calibration visit?
Program development is quoted and scheduled separately from calibration, since it depends on drawing review and validation against a known part.
What is not included in a standard calibration visit?
Mechanical repair, part cleaning, software installation and fixture alignment are not included. Each is scoped and quoted once a condition is identified.
Are ring and plug gauges calibrated along with a CMM order?
Gauges can be submitted alongside a CMM request and calibrated under the same shipment, with results reported on a separate certificate per gauge type.
What information should be included with a calibration request?
Instrument make, model, serial number, range and the last calibration date. Known faults or error codes should be listed so the request is scoped accurately.
Is a loaner or backup gauge available during repair?
Loaner equipment is not stocked. Repair timelines are communicated at quotation so inspection coverage can be planned around the outage.
