Polishing processing device for sample

A grinding machining device for samples comprises a clamping part, a lifting mechanism and a grinding mechanism. The clamping part and the lifting mechanism are arranged on the workbench; the grinding mechanism is arranged on the lifting mechanism and located over the clamping part. The clamping part comprises a circular ring, a bracket and a clamping mechanism; the circular ring is arranged on the workbench through a support. The multiple clamping mechanisms are arranged on the inner wall of the circular ring. The sample polishing efficiency is improved, and the labor intensity of workers is reduced. 一种用于样品的打磨加工装置，包括夹持部分、起降机构和打磨机构；所述夹持部分和起降机构均设置在工作台上；所述打磨机构设置在起降机构上，且打磨机构位于夹持部分的正上方；所述夹持部分包括圆环、支架和夹持机构；所述圆环通过支架设置在工作台上；所述夹持机构的数量为多个，且其均设置在圆环的内壁上。本实用新型提高了样品打磨效率，降低了工作人员的劳动强度。
