CNC Machining Glossary: English – German – Chinese
A working glossary of the machining, metrology and quality terms used across this site, with the German wording we publish and the Chinese equivalent.
How to use this glossary
Every technical term used on this site, mapped across English, German and Chinese. The German column follows the wording currently published on our German pages; terms marked ⚠ are the ones our technical translator is still deciding on. The Chinese column is a working reference for procurement and engineering colleagues.

Terms awaiting translator confirmation
The entries marked ⚠ follow our current published wording but are being reviewed by a German technical translator specialised in plastics and CNC machining. Once the review is complete this glossary is updated, so it always reflects the shipped site.
FAQ
Frequently asked questions
The plant, the engineering team and most suppliers work in Chinese, so the third column is how the same term is discussed internally. It keeps a single reference for drawings, purchase orders and shop-floor talk.
The ones marked with a warning sign. They follow the wording published on our German pages today, and a technical translator is reviewing them - the glossary is updated once the review is done.
As a reference, yes. It reflects how a contract machine shop actually uses these words, not a generic dictionary. For anything contractual, ask us and we will confirm the exact term used in your documents.
Yes - inspection reports, material certificates and correspondence can be issued in German or English, and our German partner Tubacon GmbH handles local contact.
