Metallographic sample grinding polishing machine M-1Pro+

for sample preparationmanually-operatedsingle

Product overview
The M-1Pro+ is a single-disc benchtop metallographic grinding and polishing machine designed for stable rotation, compact installation and low noise. Equipped with a water-cooling system, it prevents specimen overheating during grinding and preserves metallographic structure. The unit supports rough grinding, semi-finish grinding and finish grinding prior to polishing and microscopic microstructure analysis, and is intended for industrial, research and educational laboratories.

Key features

• Automatic pressure measurement function (developed in-house by Laizhou Weiyi): displays applied pressure in real time during manual grinding.
• Water-cooling system to prevent specimen overheating.
• Single-disc benchtop design: compact footprint, stable and low-noise operation.
• Stepless speed control 0–1400 r/min via knob and four fixed-speed settings.
• Adjustable disc rotation direction (clockwise/counterclockwise).
