Special polishing machine for metal 3D printing substrate

Abstract

The invention provides a special polishing machine for a metal 3D printing substrate. The special polishing machine for the metal 3D printing substrate comprises a drive mechanism, a transmission shaft, a polishing disc and a clamp, wherein the drive mechanism is in driving connection with the transmission shaft; the free end of the transmission shaft is connected with the polishing disc; the clamp used for mounting the substrate is arranged above the polishing disc; and the metal 3D printing substrate is contacted with the polishing disc. With the structure, two hands can be released, the physical labor can be reduced, injuries can be prevented, and the substrate can be kept in a horizontal state all the time, so that the polishing effect meets the requirements; and in addition, a sampleis difficult to keep horizontal with the hands. The designed novel polishing machine tool provided by the invention can effectively solve the problems, is simple in structure and convenient to disassemble and use and the like.

Description

technical field [0001] The invention belongs to the field of 3D printing, and in particular relates to a polishing machine specially used for metal 3D printing substrates. Background technique [0002] In the process of metal 3D printing, usually after the printing is completed and the parts are removed, there will be residual support on the substrate. Generally, the residual support on the substrate surface will be removed by a polishing tool to obtain a smooth surface. The polishing tools we usually use include sandpaper, files, etc. During the polishing process of hand-held polishing tools, it is labor-intensive and its polishing efficiency is low and the polishing effect is poor. If a metallographic polishing machine is used for polishing, the substrate cannot be fixed, and the sample needs to be polished by hand to apply pressure on the rotating polishing disc, which is dangerous and cannot maintain the level. Contents of the invention [0003] The purpose of the pre...
