YMPZ-2-300 (250) metallographic sample grinding and polishing machine，It is a grinding and polishing equipment controlled by a single-chip microcomputer. The body is made of ABS material, which is novel and beautiful in appearance, corrosion-resistant and durable. The grinding disc can be adjusted steplessly, supporting forward and reverse rotation, and the pressure of the grinding head supports two modes of center pressure and single point pneumatic. A special running fit design is used between the grinding wheel sample disc and the grinding disc to effectively improve the quality of grinding and polishing. High-definition LCD touch screen control and display, easy to operate, clear and intuitive. The motor is a DC brushless motor, which requires no brush replacement. It has a long service life and very quiet operation. The powerful motor power brings an efficient grinding and polishing experience. Double disc design, grinding and polishing can be operated independently. The design of precision cast iron supporting chassis ensures precise slewing balance; the leak-proof design of the main shaft effectively protects the bearings. The grinding disc adopts a special magnetic design, which supports fast disc replacement. The surface of the chassis and pad is treated with Teflon, and there is no sticking residue of sandpaper.
This machine's automatic grinding system can effectively replace the manual grinding and polishing processes. The number of specimens can be clamped up to 6, which greatly saves labor, improves the grinding and polishing quality and the sample preparation efficiency.

Scope of application
● Various metallographic samples
● Daily large-scale sample preparation tasks
● Light labor demand

Equipment maintenance
? Do not apply excessive pressure to the specimen during polishing to avoid damage to the motor due to overload.
? Do not use damaged fabrics for grinding and polishing to avoid affecting polishing quality and causing accidents.
? After use, clean and maintain it in a timely manner every day to remove the dirt deposited in the drain pan and drainage pipe to facilitate the smooth drainage. When not in use, cover it with a plastic cover in time to prevent debris from leaking into the pan. , Affecting the quality of future grinding and polishing
? After long-term use of this machine, the grease in the motor bearing should be replaced in time, usually once every 12 months.
