The appearance of the machine is novel and beautiful. The dirt collecting pan and shell are made of thick ABS plastic blister

process. The machine is durable and easy to maintain. This machine adopts vector frequency converter to adjust the speed in a

large range to adapt to the different speed requirements of grinding and polishing in the sample preparation process (the speed can

be adjusted between 50-1000 rpm arbitrarily), and it can be adjusted according to the usage habits. This makes the machine more

widely applicable and is an indispensable equipment for users to make metallographic samples. The speed of the left and right discs

of the machine can be adjusted independently. The double discs can simultaneously grind and polish the sample. When using, only

need to change the sandpaper and polishing cloth of the grinding disc to complete the rough grinding, fine grinding and drying of

various samples Various processes such as grinding, wet grinding and polishing.
