Description
Technical field
The invention belongs to metallographic specimen polishing processing technical fields, use more particularly, to a kind of automatic grinding and polishing machine of metallographic specimen
Bed die grip device.
Background technique
Material is the material base of human being's production and life, and the mechanical property of metal material not only has with its chemical component
It closes, also there is close pass with institutional framework, so needing to carry out Metallographic Analysis understands relationship between each material, however in gold
Before facies analysis, then needs to prepare metallographic specimen and be used to carry out observation inspection.Metallographic specimen preparation include sample, inlay, polishing and
Polishing, so what the quality of metallographic specimen was finally determined by polishing process, the polishing of metallographic specimen is metallographic sample preparation preparation process
In important link, quality of finish directly affects Metallographic Analysis, if serious destroy will cause false group of metallographic specimen
It knits, to detect inaccuracy.The main method polished at present to metallographic specimen includes mechanical polishing, electrobrightening, chemistry
Polishing and composite polishing etc. guarantee the good metallographic specimen of acquisition wherein mechanical polishing is widely used polishing method,
