  • Intro

    Since 1924 BLOHM flat and profile grinding machines have been used worldwide wherever precision, performance and productivity are required. More than 15,000 delivered machines reflect the international recognition of BLOHM grinding machines. Constant advancements and a spirit of innovation have characterised the company's varied history since its foundation.

  • The founding years

    • Foundation of the Robert BLOHM company in Hamburg. Factory for measuring instruments and apparatus construction in Hamburg. (1924)
    • Development of the legendary WURI II machine tool. (1937)
    • Development of a flat grinding machine with ball guides. (1948)
  • An up-and-coming company

    • Introduction of creep feed grinding with a BLOHM HFS (1962)
    • Takeover by Hauni-Werke, Hamburg. (1978)
    • Introduction of a new CNC creep feed grinding machine series. (1980)
  • Start of the CNC age
