Overbeck IRD Internal grinding machine
Perfect combination of components that provide optimal results
0a ird technology
Natural granite base

Machine bed made of natural granite, the optimal material for achieving the highest accuracy.

Linear motors

Linear motors deliver highly dynamic transmission of power. The technology achieves fast and precise movements that guarantee maximum productivity and quality.


Carefully built in our own facilities with high quality components for long life. All this helps to ensure that the workpieces have the optimum quality you are looking for.

Grinding spindles

High quality spindles with high precision bearings with air/oil or lifetime lubrication.

We grind every type of application: Heavy, small, non-round…

Direct driven spindle turret  with 300° swivelling range and the capacity for up to 4 spindles and one measuring probe.

  • Different workheads depending on the weight of the workpiece
  • The B0 axis is designed to help grind high precision parts with very precise shapes and surface finishes, including 3-axis interpolation with the X and Z axes to create part contours
  • Three jaw chuck (automatic or manual)
  • Magnetic chuck
