Sample preparation

Grinding/Polishing Machine

The Struers Prepamatic-2 is a fully automatic microprocessor-controlled system for grinding and polishing of metallographic samples and specimen for the subsequent deposition of coatings. It is equipped with a grinding stone and four grinding/polishing stations. Up to six samples can be mounted in the sample holder and prepared at the same time.


Technical data:

  • Fully automatic grinding and polishing machine with grinding stone and four grinding/polishing stations
  • Sample holder for up to six samples

Blasting Cabinet

The blasting cabinet WIWOX DP14 EU is used for mechanical cleaning of surfaces and for removal of coatings. Dry pressure blasting is done with pressurized air and corundum as blasting medium.
