Ultraprecision Machining

The ultraprecision machining is an integral part of the Institute of Micro Production Technology. The IMPT has many years of experience in the processing of materials such as with abrasive cutting and chemical mechanical polishing. The processing of materials takes place here in the lab and not in the cleanrooms of the IMPT.

Offer Spectrum

The opportunities of a collaboration in research and development or in a small contract are diversified and the following works represent only an overview of the opportunities at the IMPT. For your specific needs, please contact Mr. Dipl.-Ing. Manuel Stompe. Of course, you can also get information about the research areas, projects and facilities at the IMPT.

 

  • Isolation (by dicing) of brittle materials (ceramic, Si, Poly-Si, glass) up to 2 mm substrate thickness.

  • Isolation (by dicing) of thin ductile materials (sheet metal, films) up to 0.2 mm substrate thickness.

  • Isolation (by dicing) of several synthetic materials (PMMA, polycarbonate, PP, POM) up to 3 mm substrate thickness.

  • Profiling (V or U-profiling) (by dicing) of the materials mentioned above.

  • Performance measurement and analysis of the abrasive cutting process (dicing) when processing the materials mentioned above.

  • Plane lapping of various materials (ceramics, Si, Poly-Si, glass, steels)

  • Plane grinding of brittle materials (ceramics, Si, Poly-Si, glass, CBN-, diamond layers)

  • Grinding of inclinations in the substrate (ceramics, Si, Poly-Si, glass, steels, several synthetic materials)

  • Polishing of various substrates (ceramics, Si, Poly-Si, glass, steels, several synthetic materials)

  • Polishing of thin film technologically-produced layers: galvanic, sputtered, vaporized, CVD, etc.
