Abstract

The invention discloses a metallographic specimen grinding and polishing machine. An upper supporting plate and a lower supporting plate are arranged on a machine body; a grinding and polishing bottom plate is arranged in the middle of the upper supporting plate and is enclosed by a drainage tank; two ends of the upper supporting plate are provided with an abrasive belt driving shaft and an abrasive belt transmission shaft; a pressing plate is correspondingly arranged on the upper part of the grinding and polishing bottom plate; a screw is arranged on the pressing plate; a rotary pressing disc and a specimen fixture disc are arranged at two ends of the screw; an abrasive belt adjusting shaft is arranged in an adjusting groove on the lower part of the upper supporting plate; a water tank and a motor are arranged on the lower supporting plate; water is supplied to the grinding and polishing bottom plate through a water pump; the motor drives the abrasive belt driving shaft; and the abrasive belt is tensioned on the abrasive belt driving shaft, the abrasive belt transmission shaft, an abrasive belt supporting shaft and the abrasive belt adjusting shaft. The metallographic specimen grinding and polishing machine is simple in structure, convenient to operate and high in specimen manufacturing efficiency, and can effectively guarantee the manufacturing quality of a metallographic specimen.

Description

technical field [0001] The invention belongs to the technical field of sample grinding and polishing equipment, in particular to a grinding and polishing machine. Background technique [0002] In the process of studying the structure properties of the material matrix and the surface integrity during processing, it is necessary to cut the material to be observed, and prepare a mosaic sample for tissue observation on a metallographic sample mounting machine, and then grind and grind the mosaic sample. Polish to make a sample for metallographic observation, and finally perform performance test and observation. In this process, the grinding and polishing of metallographic samples is the most important and most difficult step to control, which often requires long-term grinding and repeated observation by experienced and skilled preparation personnel. [0003] In the prior art, there is a special polishing machine disclosed for the preparation of metallographic samples, which is ...
