Automatic Metallographic Grinding and Polishing Machine G-MP2000

The Automatic Metallographic Grinding and Polishing Machine is a  high-precision, double-disk bench-top system designed for automated sample  preparation. It features six-specimen clamping, touch-screen control, and  stepless speed regulation for both grinding and polishing heads, allowing  forward and reverse operation. Equipped with dual water-cooling, it prevents  overheating and flushes debris, ensuring sample integrity. The ABS body is  durable and corrosion-resistant. Ideal for laboratories, universities, and  research institutes, it delivers smooth, low-noise, efficient, and reliable  metallographic specimen processing.

Fashionable appearance, automatic clamping specimen, no need to manually hold  the specimen, six specimens can be made at a time, improve work efficiency.

Parameters

Features

This machine is a double-disk automatic single-point pressurized bench-top  metallographic grinding and polishing machine. It is based on international  standards and uses advanced global technology to manufacture a new generation of  high-precision, automated grinding and polishing equipment for the sample  preparation process. The machine uses an advanced microprocessor control system,  allowing the rotational speed of the grinding and polishing discs and heads to  be infinitely variable. Human-computer interaction is facilitated via a  touch-screen, making the setting of sample-making pressure, time, and  forward/reverse direction more intuitive and convenient. Only replacing the  grinding and polishing disk, sandpaper, or fabric is required to complete the  grinding and polishing process.

It features smooth rotation, safety, reliability, low noise, and strong  rigidity, making it suitable for a wide range of applications. The machine is  equipped with two water-cooling devices to cool specimens during grinding,  preventing overheating and damage to the metallurgical structure while  continuously flushing away abrasive particles. The body is made of ABS plastic,  giving it a novel, aesthetic, corrosion-resistant, and rust-proof appearance.  The grinding and polishing head includes a locking handle for easy rotation and  operation.

This automatic grinding and polishing machine is suitable for rough grinding,  fine grinding, and rough-to-fine polishing of metallographic specimens. It  provides high production accuracy with surface roughness not exceeding 0.2 Ra.  The machine can handle a variety of materials, allows independent operation of  grinding and polishing disc speeds, operates quietly, is easy to use, and has an  attractive and safe design. It is ideal equipment for enterprises, research  institutes, universities, and laboratories for sample preparation.
