Description

technical field [0001] The invention relates to a nickel base alloy sample clamping mechanism specially used for a surface grinder, specifically, it is mainly used for surface grinding of nickel base alloy plates with a thickness of 25-40 mm. The invention belongs to the technical field of grinding processing of nickel base alloy samples. Background technique [0002] High-precision nickel-based alloy plate is a kind of specimen widely used in the field of material testing. Because of the non-magnetizable physical characteristics of the material, it is impossible to directly use the electromagnetic platform to adsorb for processing. At present, most of the industry adopts the rosin bonding method to fix the sample. During the grinding process, due to gap vibration, it is easy to cause scaly ripples on the surface of the sample, which seriously affects the grinding quality; moreover, the binder residue on the sample is difficult to remove, which seriously affects the process...

Problems solved by technology

Due to the physical characteristics of the material that cannot be magnetized, it is impossible to directly use electromagnetic platform adsorption for processing operations. At present, most of the industry adopts rosin bonding method to fix the sample. During the grinding process, due to gap vibration, it is easy to cause scaly ripples on the surface of the sample, which seriously affects the grinding quality; moreover, the binder residue on the sample is difficult to remove, which seriously affects the processing efficiency and damages the surface of the machine table. cause chemical corrosion
