The company HMM Hartmann GmbH is an operation of cutting technology with currently 20 employees.

The company was founded by Heinz-Dieter and Michael Hartmann 1998.

Equipped with advanced CNC milling and CNC turning machines, we produce precision parts for the machines and special machinery.

Turning and milling parts are machined from steel, stainless steel and non-ferrous metals like aluminum, brass and copper.

Depending on requirements, the machine parts are subjected to after machining heat treatment or surface treatment.

In this way we can always deal with the different orders reliably and competently.
