Improving machine autonomy
Founded in 1923 in Switzerland as a mechanical repair shop, STRAUSAK, today a subsidiary of ROLLOMATIC HOLDING SA, served the watch making industry until diversifying its product range in the early 1970’s.

For several years running, STRAUSAK’s 5 Axis CNC-Tool Grinding Machine, known simply as U-Grind, has been providing customers with a reliable, efficient and highly accurate system for their grinding and re-sharpening needs.
