About MA MicroGrind
MA MicroGrind GmbH, headquartered in Rinteln, develops and produces specially vitrified (ceramic-bonded) CBN and diamond grinding tools for double-disc grinding and fine grinding (flat honing). In addition to grinding wheels, the portfolio includes dressing technology for these grinding processes. The tools are continuously developed in collaboration with customers according to their requirements; on site, the grinding systems are optimized into an economical production technology with the required surface quality. Only qualified raw materials are used in production; depending on the task, various bonds are employed, which decisively influence the grinding process and grinding result. Users of the grinding tools include the automotive and rolling bearing industries as well as the tool, steel and ceramics industries. Since 2026, the company has been part of the Diprotex Group (Saint-Egrève, France) and serves customers worldwide.
