During the preparation of metallographic specimen, the surface of the cut specimen or the surface of the unprocessed specimen is rough and uneven. In order to improve the quality of the specimen preparation and the working efficiency, the cut section of the specimen may be first grinded on the grinding machine and then be pre-grinded and polished. MPJ-25 metallographic sample grinding machine is designed according to the various technicians and various requirements. As a bench machine, it is suitable for the water grinding, dry grinding and lap cutting, easy to operate and maintain with high safety and reliability. The sewage collection disc and cover are made of stainless steel, which is the excellent machine for metallographic sample preparation
