Horizontal type metallographic phase grinding and polishing machine

Abstract

The invention discloses a horizontal type metallographic phase grinding and polishing machine which comprises a base, wherein a feeding mechanism and a grinding and polishing mechanism are correspondingly arranged on the base; the feeding mechanism comprises a lead screw and a fine adjustment rotary shaft; the lead screw is driven by a feeding drive motor to realize automatic feeding; the fine adjustment rotary shaft is driven by a hand wheel to realize manual fine adjustment so as to precisely control the grinding amount; the grinding and polishing mechanism comprises two grinding and polishing discs; the two grinding and polishing discs can do progressive rotation to work alternately; and when one grinding and polishing disc works, the other grinding and polishing disc changes abrasive paper and the grinding and polishing operation is not stopped, so that time is saved, and the working efficiency of the horizontal type metallographic phase grinding and polishing machine is greatly improved. In addition, the horizontal type metallographic phase grinding and polishing machine adopts the horizontal type structure as a whole, and a transparent observation window on a protective cover is cooperated to conveniently observe the metallographic phase grinding and polishing situation.

Description

technical field [0001] The invention belongs to the technical field of grinding and polishing machines, in particular to a horizontal metallographic grinding and polishing machine. Background technique [0002] Metallographic grinding and polishing machine, referred to as grinding and polishing machine, is a kind of grinding equipment. It uses water-resistant grinding metallographic sandpaper of various particle sizes to perform rough grinding and fine grinding on various metals and their alloy samples as well as various petrographic samples. Grinding, dry grinding, wet grinding and other grinding processes, rough processing before polishing, and can be used as polishing samples at the same time. But the grinding and polishing machine of the prior art is generally a vertical grinding and polishing machine, and its grinding and polishing disc is just one, and it needs to stop and wait when changing the sandpaper, so the working time is wasted, and the work efficiency is not h...

AI Technical Summary

Problems solved by technology

However, the grinding and polishing machines in the prior art are generally vertical grinding and polishing machines, and there is only one grinding and polishing disc. When changing the sandpaper, it is necessary to stop and wait, so the working time is wasted and the work efficiency is not high.

Moreover, it is not easy to observe the metallographic grinding and polishing situation, and it is difficult to fine-tune and control the grinding amount
