Cutting is the first step of material analysis. The selection of cutting machine and cutting wheel must comply with the geometric size and material characteristics of the sample. The perfect metallographic cutting should avoid microstructure thermal damage and deformation, and preserve the necessary accuracy and efficiency.
Hardness and ductility are the two main parameters for selecting the cutting wheel. The best choice of the cutting wheel depends on the size, hardness and ductility of the material and the equipment used. Trojan's cutting products speak with facts and the cutting process is simple, fast and accurate.
Polishing is to use a small amount of polishing powder or polishing liquid to place on polishing cloth, later the sample is polished.Purpose of polishing is to remove the deformation and scratches during the grinding process,resulting in a scratched mirror surface for microscopic analysis of the microstructure.
