Post-processing of additively manufactured components

With additively manufactured components (rapid prototyping or 3D printing), there is often a need to improve the surface quality. With the help of abrasive flow machining, the surfaces in internal channels and complex component geometries in particular can be processed and excellent results achieved.

Spare parts even after years 

Are your abrasive flow machines still doing their job safely and tirelessly for many years? Have your cleaning systems also been in use for many years thanks to their robustness? With expert maintenance, older machines will continue to function perfectly and reliably even after decades.

Efficient processing of extrusion dies 

Extrusion dies must be reworked and optimized by skilled professionals in laborious work by hand. These works increasingly result in higher tool price. The use of MicroStream abrasive flow machining leads to a significant cost reduction while improving the quality of the end product.

AFM-Medium streamer – the liquid file

The central tool for the mechanical removal process of Micro Stream abrasive flow machining is the streamer. It is individually adapted to the material to be processed, the component geometry and the desired surface quality. This supports the process decisively, reduces machining times and delivers the best surface qualities.

Comfort Line – permanently slimmer!

MicroStream abrasive flow machining systems assist you in the grinding and deburring of difficult to reach internal bores as well as the rounding of edges or the polishing of milled, turned or cast components – and all completely independent of their geometric shapes.

Our products stand forhighest quality and reliability, and we are constantly working to improve them for your benefit. OurComfort Line therefore now also comes in aspace-saving design.

Do you already know our Streamer?

Did you know that the optimal selection of the abrasive medium, which we call the Streamer, contributes significantly to the success of abrasive flow machining?
The use of a Streamer that is adapted to your processing task provides decisive support for your process, reduces processing times and delivers the best surface qualities.

Expansion thanks to reduction?

Expansion and reduction are not mutually exclusive in this case. By installing our reducing kit, you decrease the cylinder diameter of your abrasive flow machine and thereby expand your processing spectrum. As a result, you are perfectly prepared for both test processing as well as serial production, for small, delicate and large components - all with one machine.

We are your partner for contract manufacturing

For components with traditional production methods, and for additively manufactured components in particular, there is often a need to significantly improve the surface quality, especially if they have hard to reach, internal surfaces. We would be happy to process your workpieces as a service provider at our contract manufacturing site in Freiberg am Neckar.
See the quality of our machining for yourself, and the opportunities it opens up for your individual workpieces. We are happy to create an initial feasibility analysis for your components based on drawings.

Optimization of medium piston in the grinding process of inside surfaces

With our abrasive flow machining process you can achieve significant improvements in the surface quality of your processed workpieces. The new, modular medium pistons from Micro Surfaces minimise the number of spare part replacements you will have to make in future. In the event that a sealing edge wears out, only the piston seal and, after even longer run times, the guide band need to be replaced.

More powerful hydraulic aggregate and optimised software

Perfect coordination of all components forms the basis for first-class product quality. Our systems now have a more powerful hydraulic aggregate. In conjunction with optimised software this leads to an even more stable process and thus to the best grinding results.

The new heating/cooling system with anti-condensation coating

The temperature of the STREAMER abrasive medium has a high impact on the processing quality. We have developed a significantly improved heating/cooling system and redesigned the heat exchanger. These measures ensure that the medium remains at a consistent temperature. Moreover, an additional anti-condensation coating increases the service life of the Streamer.
