Manufacturers
Grinding machine manufacturers
A working directory of the CNC grinding machine builders that US buyers actually run into — who they are, where their US operation sits (or that they publish none), what they build, and how to reach them. Compiled from public sources. We match applications to machines; this directory is the map.
How this directory works. Listings are factual and informational — builder name, headquarters, US presence, machine types, official site — written in our own words from public sources. No manufacturer pays to be listed, and listing implies no endorsement in either direction. Grinding Advisor has a referral arrangement with one importer listed in this directory (ST Grinders, for Supertec machines). Every other listing is informational only, and no manufacturer pays to be listed. Listed companies: if a fact here is wrong, tell us and we’ll fix it the same day.
