Precision parts for the highest demands

We start where others stop - our experts take on almost every machining challenge.

The machining of high-alloyed nickel-base alloys such as Inconel, Hastelloy and titanium alloys is part of our day-to-day business, but we also process aluminum efficiently and with the necessary care.

From highly stressed parts for gas and steam turbines and turbochargers to optically flawless visible parts for medical technology, we have the right machine for every part at hand.

Turning

In our turning shop, single and serial parts up to a diameter of 1'000 mm are produced precisely. Narrow fits we grind after a few thousandths of a millimeter exactly. Whether components made of tempered steel or hardened shafts, we get every part going!


Our specialties include:

  • Valve and pump parts such as housings, spindles, pistons and bearings
  • Radial and axial bearings for turbines and turbochargers
  • Turning and grinding turbocharger compressor wheels
  • Gas turbine parts such as flanges and burner lance parts
  • Coupling and connecting bolts
  • Measuring and calibration shafts as well as hardened tool inserts

 

Miling

The 5-axis machining of high-alloyed materials such as nickel-base alloys is one of our core competencies. In addition, we are able to process complex castings with a dimension of up to one meter and then carry out the necessary leak tests. Our customers benefit from our decades of experience in the development and manufacture of clamping devices, which drastically reduce machining times.


Our specialties include:

  • Pumps and valve housing
  • Strainer body for gas and steam turbines
  • Gas turbine parts such as blades, combustors, and gaskets
  • Operating elements for medical applications
  • Current-carrying contact elements for switchgear

 

Flat and cylindrical grinding

We give the finishing touches to precision parts - whether components for punching tools or hardened valve spindles we grind in the micrometer range.

We use a variety of flat and cylindrical grinding machines and ensure perfect dimensional accuracy by means of well-equipped quality assurance. 

In addition, we can look back on decades of experience in the field of wire and sink erosion and are thus in a position, together with our partners, to manufacture even more complex geometries in very hard materials.

Sample products

Highly stressed gas and steam turbine parts

Aartech manufactures gas turbine parts with high tolerance and heat resistance requirements for the market leaders in energy technology, for new systems as well as for service projects.
The entire process takes place almost in-house. Starting with the cutting of raw materials by means of laser cutting, the processing of the individual parts by means of optimized milling processes, assembly by welding and vacuum brazing, through to functional and dimensional testing and documentation of the test results.

Complex milled parts for space travel

Some of our parts flew further than the planet Mars. We are proud to produce heavy-duty structural parts made of aluminum and titanium, which are used in the aerospace industry, for example for drive brackets, solar panels or rocket tips.
These structural parts are exposed to very high loads, must meet strict quality requirements and have the lowest possible weight. On our high-precision and flexible 5-axis milling machines, we efficiently process aluminum, titanium and nickel-base alloys to the nearest hundredth of a millimeter and ensure flawless product quality using 3D CNC measuring machines.
