The YMPZ-2-250 metallographic sample grinding and polishing machine is a grinding and polishing equipment controlled by a single-chip microcomputer. The body is made of ABS material and has a novel and beautiful appearance, corrosion resistance and durability. The grinding disc has stepless speed adjustment and supports forward and reverse rotation. The grinding head pressurization supports two modes: center pressure and single-point pneumatic. The unique running fit design between the grinding head sample disc and the grinding disc effectively improves the grinding and polishing quality. It adopts high-definition LCD touch screen control and display, which is easy to operate, clear and intuitive. The motor is a DC brushless motor, which means there is no need to replace the brushes. It has a long service life and ultra-quiet operation. The strong motor power brings an effective grinding and polishing experience. Double disc design, grinding and polishing can be operated independently. The design of the precision cast iron support chassis ensures precise rotational balance; the leak-proof design of the spindle effectively protects the bearings. The grinding disc part adopts a unique magnetic design to support quick disc change. The surface of the chassis and pad are treated with Teflon, so there is no adhesion residue from sandpaper polishing.
The automatic grinding system of this machine can effectively replace various manual grinding and polishing processes, and the number of sample clamps can reach 6, which greatly saves labor, improves grinding and polishing quality and sample preparation efficiency, and is a satisfactory choice for new automatic metallographic sample preparation equipment.
