Reasons for the test results

       1. The performance of our milling machines bases upon the dimensional accuracy 

      of our indexable inserts of a tolerance of approximately 0.01 mm. In this respect

      we set a high value on premium quality. Indexable inserts manufactured in a

      “speed-grinding” with greater tolerances or made in a pure press process are

      cheaper in production but at the same time reduce the endurance of the

      indexable inserts and, due to more vibration, the life of the milling machine.

       2. Of course, a precise concentricity of the milling unit is also essential for the

       application of high quality indexable inserts. By the contact of the indexable 

       inserts to the material the cutting depth is determined by the chosen rotation

       combined with the feed.

       In case of the high rotation speed as applied by hand guided machines, every

       imbalance has a negative impact on the result.

       3. A maximum precise and fine adjustment of height is also very important.

      This calibration helps to adjust the necessary bevel dimension as fast and

      precise as possible. 

        Conclusion:

        The more constant the inserts are manufactured, the concentricity of the

       milling unit is more precise,

       the height calibration is functioning more simply and accurate,

         the fewer inserts are needed, there is less vibration on your machine and

       the working of the component is cheaper.
