Product Description


1. Introduction
The MePao-3S automatic grinding and polishing machine is a double-disc desktop machine. It is a new generation of high-precision, automated sample preparation process grinding and polishing equipment manufactured in accordance with international standards and using international advanced technology.
This machine adopts an advanced microprocessor control system, which makes the rotation speed of the grinding and polishing disc and grinding and polishing head infinitely adjustable, and the sample preparation pressure and time settings are intuitive and convenient. The operator only needs to replace the grinding and polishing disc or sandpaper and fabric to complete the grinding and polishing process, thus making the machine more widely applicable. This machine has the functions of optional selection of the rotation direction of the grinding and polishing disk, quick replacement of the grinding and polishing disk, multi-sample holder and pneumatic single-point loading, automatic distribution of abrasives, etc. It also has the features of stable rotation, reliability, low noise and the use of cast aluminum base to increase the It has the characteristics of rigidity in grinding and polishing.
This machine is equipped with a water cooling device and an abrasive scouring nozzle, which can cool the sample during grinding to prevent damage to the metallographic structure due to overheating of the sample and to scouring away the abrasive particles at any time; it is also equipped with an ABS shell and stainless steel Standard parts are more beautiful in appearance, have improved anti-corrosion and anti-rust properties and are easy to clean.
MP-3S automatic grinding and polishing machine is suitable for automatic sample preparation of metallographic samples from rough grinding, fine grinding, rough polishing to fine polishing. It is an ideal sample preparation equipment for enterprises, scientific research institutions and laboratories of universities and colleges.
