Walther Trowal developed the ‘AM post process machines’, model range AM, especially for refining the surface of components produced with additive manufacturing.

Many materials with high ductility and tendency to stick are always a challenge in machining. Problems with the chip flow are in most cases the performance-limiting criteria.

At Zimmermann Formen- und Werkzeugbau in Gladenbach in central Hesse, the milling processes have been put under the microscope.

The capabilities for micro-machining have recently been aptly demonstrated by AMRC engineers who have used the mill-turn machine to reproduce a series of tiny portraits of Queen Elizabeth II.

Cast iron is a common material for machining. However, there is far more to the common material than first meets the eye.

With large quantities the properties of both the machine tool and the tool itself need to be optimally suited to each other – and to the chosen manufacturing process.

High infeed depths as well as the highest feeds during roughing are possible with the new Optimill-SPM-Rough, according to Mapal.

The new tool system has been developed for the machining of step-, slot- and face milling operations, in terms of roughing and finishing steels, high-grade steels, cast iron and more.

With Additive Manufacturing (AM) extremely precise component geometries can be produced that are not possible with conventional manufacturing technologies.

It looks like an over-dimensioned setscrew, but contains an interesting technical interior due to its patented wedge mechanism.
