A New Type of Metallographic Sample Polishing Device

Abstract

The invention relates to a novel metallographic sample polishing device, comprising a polishing disc main body, a sample holder and a dust cover, wherein the sample holder and the dust cover are fixed on the polishing disc main body; the polishing disc main body includes a polishing disc shell, Polishing disk, power indicator light and switch; sample fixture is composed of fixed bracket, fixed V-block module and moving V-block module, which include horizontal guide rod, longitudinal guide rod, cylindrical slider, set screw, guide rod fixed Screws, V-blocks, A-blocks, T-shaped thumb screws, positioning blocks, V-block positioning blocks, moving V-blocks and B-blocks; the dust cover includes the dust cover shell, front door, hinges and handles. The invention has the advantages of convenient, quick and environment-friendly operation, high polishing efficiency and no potential safety hazard, and can meet different polishing requirements.

Description

technical field [0001] The invention relates to the field of mechanical grinding and polishing, in particular to a novel metallographic sample polishing device. Background technique [0002] In the test of observing the metallographic structure, the traditional metallographic sample polishing machine has many deficiencies in the use process. When the operator holds the sample for polishing, the polished surface of the sample will be uneven, which will affect the subsequent observation experiments, and the uneven force of the hand-held sample will easily cause the sample to fly out, which has certain potential safety hazards. During the polishing process, a large amount of dust will be generated for some soft metal materials, which will cause certain harm to the environment and operators. When the traditional mechanical polishing device performs the test, it is difficult to polish the thin sample by hand, and the sample needs to be inlaid in advance, which is inefficient. ...
