More than 60 Years of Experience and Competence From a Single Source

The core competence of Custom Machining lies in the manufacture of precision parts from all machinable materials. Meeting customer requirements in a service-oriented and innovative manner has top priority.

Custom Machining’s customers appreciate the experience, reliability, adherence to deadlines and the associated consistently high quality and process security. They are also impressed by the full service offered from a single source - from the drawing to the finished component - as well as by flexible capacities in terms of utilization and logistics due to Rosenberger's company structure, which enables additional resources if required.

From a technological point of view, with ongoing investments, Custom Machining is fully equipped for the requirements of tomorrow. Because the increasing complexity of components and the  demanding processes in the machining of materials require future-oriented and automated production areas and technologies.

Whether it is turning, milling or manual processing -  in machining technology,  quality control or within the production processes - the services of Custom Machining set new standards in every respect.



At Custom Machining, lathes produce workpieces with a diameter of up to 500 mm and lengths of up to 1000 mm.

The production of highly complex parts is made possible by manufacturing them on the most modern turning-milling centers in one clamping



Custom Machining has milling machines that are ideally equipped for customer-specific components: from vertical production to the simultaneous machining of six component sides in one clamping.

The machining centers can machine a component size of up to 1130 mm.
