VÖLKEL Calibration service for thread ring gauges

• for the calibration of thread ring gauges for cylindrical external threads
• for GO and NO GO inspection of dimensional conformity
• for inspection equipment monitoring, incoming goods inspection, production control and quality assurance
• for service workshops, maintenance, mechanical engineering and industrial thread inspection
• for documented evaluation of thread ring gauges in an inspection equipment management system

Note For cylindrical external threads, inspection is carried out with thread ring gauges; the GO ring gauge must screw on without major resistance, while the NO GO ring gauge may only screw on by a maximum of 2 thread turns.

• factory calibration certificate directly from the manufacturer
• calibration in a measurement laboratory independent of manufacturing
• measurement on IAC thread scanners
• suitable for documented inspection equipment monitoring
• practical classification for thread ring gauges used in external thread inspection

• The factory calibration certificate does not replace proper cleaning, protected storage and visual inspection of the thread ring gauge between calibration intervals.

1. Select the thread ring gauge for which a factory calibration certificate is required.
2. Check whether the thread ring gauge is intended for cylindrical external threads.
3. Assign the test item to the relevant thread system and standard specification.
4. State the calibration request together with your order or inquiry.
5. The thread ring gauge is calibrated in the independent measurement laboratory on IAC thread scanners.
6. The results are documented in the factory calibration certificate.
7. File the certificate in your inspection equipment management system and assign it to the correct thread ring gauge.

What is the factory calibration certificate for thread ring gauges used for?
You use the factory calibration certificate to document the calibration of a thread ring gauge in a traceable way.

Which threads are checked with this thread ring gauge?
This thread ring gauge is used for cylindrical external threads. The concrete assessment depends on the respective thread system and standard specification.

What does GO and NO GO mean in thread gauging?
The GO gauge verifies that the thread can be accepted from the functional side. The NO GO gauge checks the reject limit and may only engage within the specified limit.

Do I receive a factory calibration certificate with this service?
Yes. On request, we issue a factory calibration certificate as the manufacturer for the respective test item.

Which specifications are used to calibrate the thread ring gauge?
Calibration is carried out according to the specifications and standards defined for the respective test item, for example DIN, ISO or ANSI.

Why is calibration on IAC thread scanners relevant?
Calibration on IAC thread scanners supports precise and traceable inspection of thread gauges in industrial inspection equipment management.
