The TegraPol 35 grinding and polishing machine with TegraForce 5 sample mover and TegraDoser from Struers offers the possibility of targeted sample preparation. Both for the production of defined surface roughness as well as for the production of planar surfaces, this device is the best choice for the pretreatment of joints at the trial stage. With the help of various grinding and polishing programs and the use of suitable consumables, almost all materials can be processed. Optimally prepared surfaces are thus obtained for the plasmatreater or the microscopes. The TegraForce 5 attachment makes both single sample preparations and - via central pressure - multiple preparation possible. The dosing unit ensures reproducible grinding and polishing processes.
