In the metallographic sample preparation process, pre-grinding is essential before polishing before the pipeline project, the first specimen after pre- polished, can improve the effectiveness of sample preparation, to meet the needs of a variety of materials in the pre-grinding, aircraft disc diameter greater than similar domestic products, the rotational speed of the disc is also different from similar domestic products, is an excellent specimen pre-grinding equipment .
The main parameters:
Disc diameter : 230mm Double
Sandpaper diameter : 205mm
turn Speed : 450r / min, 550r / min
Electric machines : 0.55kW 380V 50Hz
