The MoPao4S automatic grinding and polishing machine is a dual disc desktop machine, with independent control of the left and right discs. It is a new generation of high-precision and automated grinding and polishing equipment manufactured according to international standards and advanced international process technology.
This machine adopts an advanced microprocessor control system, which enables the speed of the grinding disc and grinding head to be infinitely adjustable. The setting of sample preparation pressure and time is intuitive and convenient. The operator only needs to replace the grinding and polishing disc, metallographic sandpaper, and polishing fabric to complete the grinding and polishing process, thus demonstrating a wider range of applications for this machine. This machine has the ability to freely select the rotation direction of the grinding disc, and the grinding disc can be quickly replaced; Central loading and single point loading; Automatic abrasive distribution (optional liquid separator) and other functions, as well as features such as smooth rotation, safety and reliability, low noise, and the use of a cast aluminum base to increase the rigidity of grinding and polishing.
This machine is equipped with a water cooling device and an attached abrasive particle flushing nozzle, which can cool the sample during grinding to prevent damage to the metallographic structure due to overheating of the sample and to flush away the abrasive particles at any time; Equipped with an ABS shell and stainless steel standard parts, it looks more beautiful and elegant in appearance, and improves anti-corrosion and rust resistance, making it easy to clean.
The MoPao4S automatic grinding, polishing and polishing machine is suitable for automatic sample preparation during the process of rough grinding, fine grinding, rough polishing to fine polishing of metallographic specimens. It is an ideal sample preparation equipment for enterprises, scientific research institutions, and universities and laboratories.
