A key component of the second generation of the HF series are the new machining units. The goal was to combine the benefits of the HSM spindles already known from the H series with the advantages of a motor spindle. The machining trials carried out so far and the technical data show that this has been achieved.

The second generation of the HF series comes equipped with the newly developed HELLER Spindle Units (HSU) in in-line design. These spindles are‘made by HELLER’and produced on the company’s own high-precision manufacturing line.
