1. Application:

Model MoPao 3S metallographic specimen automatic grinding and polishing machine complies with international standard, and it is new generation bench type double disks automatic grinding and polishing machine produced with advanced technology. It features automatic for specimen preparation process.

The machine is of liquid cooling device and scour nozzle, it can cool the specimen during cutting to prevent damaging the metallographic structure because of cutting heating, and at the same time it can scour the abrasive grain away with the cooling liquid.

The machine shell is made of fiber reinforced plastic, and equipped with stainless steel parts, all these make the machine appearance beautiful and exquisite, also it raises the performance of antisepsis and antirust and easy to clean.

The machine suits the whole automatic preparation process from rough grinding, fine grinding, rough polishing to final fine polishing. It is the necessary and ideal sample preparation apparatus for enterprise, science research unit and lab of junior college academy.

The machine combines several different machine functions in one, it can do pre-grinding process, fine grinding process and fine polishing process, so it saves different equipment cost.

The machine adopts special converter to adjust the rotating speed, it has two rank fixing rotating speed and stepless adjustable rotating speed. Two rank fixing rotating speed of 150rpm and 300rpm is for rough grinding, fine grinding and polishing. Stepless adjustable speed from 50rpm to 1000rpm is for advance user self setting based on needing to complete automatic sample preparation.
