Knowledge about turning of small bores

In this project the manufacturing of small bores with a diameter of 4-5 mm and a L/D (length-to-diameter) ratio of 5 by means of hard turning was enabled.
This is a step way beyond the state of the art because up to now the maximum L/D ratio with which hard turning of bores could be realised was 3. In close co-operation of Hamoedia with the Fraunhofer IPT a solution was found to develop rigid tools, which enabled reliable machining of the small, bores in question within tolerances of 2-3 micons.
