‌YMPZ-2-300 Automatic Grinder & Polisher – Precision for High-Volume Labs‌
‌When ‌speed and precision‌ can’t wait, the YMPZ-2-300 delivers. With ‌6-sample automation‌, ‌300mm industrial discs‌, and ‌160N programmable pressure‌, this machine crushes deadlines for aerospace, medical, or automotive labs. Features a ‌touchscreen interface‌, ‌10 saved workflows‌, and ‌zero-maintenance DC motor‌. CE-certified, ships in ‌5–8 days‌.

‌Key Features ‌

‌6-Sample Automation‌: Process titanium, ceramics, or composites simultaneously – triple throughput.
‌300mm Discs‌: 20% larger surface area vs. competitors – faster prep, fewer disc swaps.
‌Precision Pressure‌: 0–160N central pressure (hard alloys) or 0–50N individual control (delicate materials).
‌10 Custom Workflows‌: Save settings for steel (1400 RPM, 120N) vs. aluminum (600 RPM, 40N).
‌Touchscreen Simplicity‌: LCD interface – set time, RPM, pressure, rotation direction (↻/↺).
‌Magnetic Disc System‌: Swap polishing cloths in 10 seconds – no residue, no tools.

YMPZ-2-300/250 Automatic Metallographic Sample Grinding and Polishing Machine

In the metallographic sample preparation, pre-grinding, polishing and grinding are the indispensable procedures. This machine is controlled by single chip microcomputer. With beautiful appearance, stable performance and convenient operation, it realizes the automation of grinding and polishing. Therefore it is the ideal equipment for metallographic sample preparation.

Features:

1. New and beautiful appearance, ABS material integral forming.

2. It adopts high definition LCD touch screen, clear to display and easy to use.

3. DC brushless motor, used for a long time; super mute design brings a good experience.

4. The grinding disc is made of stainless steel, firm and steady.

5. Strong large support chassis design ensures the precision rotary balance.

6. Spindle leak-proof design ensures the bearing without damage.

7. The size of the disc is larger than the same products in the market, adapted to various materials preparation of test samples.

8. Grinding disc stepless speed, clockwise or anticlockwise rotating direction, which makes the sample smooth and clean.

9. With magnetic grinding disc design, it supports for fast disc replacing system, the plate is Teflon painted which makes no residue of changing polishing cloth.

10. Equipped with the automatic grinding head, it replaces the manual grinding and polishing. And it can set time and rotating speed of grinding head, with lighting system, it improves the grinding and polishing quality and efficiency of samples.

11. It can store ten kinds of grinding and polishing procedure, set different parameters for different samples.

12. With optional ZDD-1 automatic dropping device, it can set time and drop uniformly for the suspension.
