In the process ofpreparation of metallographic sample, pre grinding, polishing and grinding arethe indispensable procedures. This machine YMPZ-2 is produced with PPC sewagecollection plate and cover and is the latest product with a new and beautifulappearance. This machine is controlled by single chip microcomputer, grindingdisc 100RPM-1400RPM of stepless speed regulation with digital tube display. Themotor is DC brushless motor and don’t need to replace the brush, used for along time. The machine is non-toxic painted. Strong large support chassisdesign ensures the precision rotary balance. Powerful motor brings strong powerand efficient grinding and polishing experience. Spindle leak-proof designensures the bearing almost without damage and the super mute design brings agood experience. It supports for fast disk system, with the use of elasticity,and can be used with automatic grinding device. It can replace the manual grindingand polishing of the procedure, timing and set the speed of grinding head. Itcan increase the grinding quality and production efficiency and is the idealmetallographic sample preparation equipment. This machine can be adapted tovarious materials preparation of test samples. The polishing disc diameter islarger than the domestic similar products. The platen speed of polishing discoperates independently. It is the best equipment of metallographic samplepreparation.
