BMP-2 metallographic sample polishing machine is a grinding and polishing equipment controlled by single chip microcomputer, double disk independent control, the body is made of ABS material integrated forming, novel appearance, corrosion resistance, durable; The solid design of large supporting chassis ensures the precise balance of rotation; Stepless speed adjustment or four speed adjustment, can change the direction of rotation; The motor is a maglev motor with long service life and low noise. The powerful torque of the motor brings powerful power, with efficient grinding and polishing experience. The spindle leakproof design ensures almost no damage to the bearing; Equipped with cooling water pipe, can adjust the rotation direction for wet grinding; Equipped with the bottom of the grinding disc flushing function to prevent the accumulation of grinding materials precipitate; The plastic disc is used as the grinding disc, and the sandpaper is buckled on the grinding disc by tight circle, and the back rubber polishing cloth is stuck on the grinding disc; When using, only the replacement of sandpaper and cloth, can complete the coarse grinding, fine grinding and polishing of various samples and other procedures, double head configuration to improve the efficiency of sample preparation, is the ideal choice of metallographic sample preparation equipment.
