METALLOGRAPHIIC SAMPLE GRIINDER//POLIISHER METALLOGRAPH C SAMPLE GR NDER POL SHER MODEL: MPD200//250E MODEL: MPD200 250E Applications: This type of metallographic sample grinding and polishing machine is a double-disc machine, which has the functions of arbitrarily selecting the rotation direction of the grinding and polishing disc,and the function of quickly replacing the grinding and polishing disc. This machine adopts an advanced microprocessor control system, which can be used for two persons to perform grinding and polishing operations at the same time. This machine has the characteristics of stable rotation, and is equipped with a water cooling device, which can cool the sample during grinding to prevent damage to the metallographic structure due to overheating of the sample. It is an enterprise, scientific research Ideal sample preparation equipment for units and laboratories of colleges and universities. Specification: Model Diameter of grinding and polishing disc: (step-less speed adjustable) (step-less speed adjustable) Speed of grinding and polishing disc Grinding and polishing disc rotation Input voltage clockwise or counterclockwise adjustable Single-phase Constant speed setting 150 r/min, 300 r/min, 600 r/min, 1000 r/min (four-level constant speed) Input power
