Hembrug rgb 0
Since 1973

Leaders in hard turning. More than 50 years and 700 high-precision turning solutions developed for customers all around the world.

Ultraprecision

Hembrug machines are among the most accurate in the world.

 

  • Dim. tolerances of ≤ 2 µm 
  • Roundness of ≤ 0,5 µm 
  • Ra of 0,1–0,4 µm 
    > 25 years

    Accuracies last more than 25 years. Hembrug offers fully hydrostatic finish hard turning solutions.

    Hydrostatic technology enables wear-free operation in the main spindle and slides.

    Complete complex workpieces with sub-micron tolerances

    Hembrug is ideal for machining complex and hardened workpieces in a single set-up and with sub-micron qualities. 

     

    You won’t need further post-processing and quality control will be less intensive, cutting your cost.
