‌Key Features ‌

• ‌Auto Grinding Head‌: Replaces shaky hands – 20-120 RPM stepper motor ensures consistent pressure.
• ‌60N Muscle‌: Adjust force for soft aluminum (20N) or titanium (60N) with a single dial.
• ‌Stepless Speed‌: Dial in 450 RPM for rough grinding or 150 RPM for mirror finishes.
• ‌ABS Armor‌: Toxic-free, chemical-resistant housing survives daily lab abuse.
• ‌4-Sample Capacity‌: Process batches faster – no reloading every 10 minutes.

YMPZ-1 Automatic Metallographic Sample Grinding and Polishing Machine

In the metallographic sample preparation, pre-grinding, polishing and grinding are the indispensable procedures. This machine is produced with ABS sewage collection plate and cover and is the latest product with a new and beautiful appearance. This machine is controlled by single chip microcomputer, with grinding disc stepless speed regulation and digital tube display. The motor is DC brushless motor and don’t need to replace the brush, used for a long time. The machine is non-toxic painted. Strong large support chassis design ensures the precision rotary balance. Powerful motor brings strong power and efficient grinding and polishing experience. Spindle leak-proof design ensures the bearing almost without damage and the super mute design brings a good experience. It supports for fast disc replacing system, with the use of elasticity. Equipped with the automatic grinding head, it replaces the manual grinding and polishing. And it can set time and rotating speed of grinding head, which improves the grinding and polishing quality and efficiency of samples. This machine can be adapted to various materials preparation of test samples, with low noise, convenient operation, beautiful appearance and safe use, it is the ideal equipment for metallographic sample preparation.
