Description

A kind of rock thin section polishing device

Technical field

The utility model relates to the technical field of polishing equipment, and specifically to a rock slice polishing device.

Background technique

Rock thin sections mainly refer to some rock ore identification samples obtained in geological work, and can generally be divided into two categories: rock light sections and rock thin sections. Thin-section petrology is one of the most basic petrological research methods. In the process of making rock thin sections, rock samples need to be polished. Polishing refers to a processing method that uses mechanical, chemical or electrochemical effects to reduce the surface roughness of the workpiece to obtain a bright and smooth surface. It is the modification of the workpiece surface using polishing tools and abrasive particles or other polishing media. Polishing cannot improve the dimensional accuracy or geometric shape accuracy of the workpiece, but is intended to obtain a smooth surface or mirror gloss. Sometimes it is also used to eliminate gloss (matting). Usually a polishing wheel is used as a polishing tool. The polishing wheel is generally made of multiple layers of canvas, felt or leather, with metal discs clamped on both sides. The rim is coated with a polishing agent evenly mixed with micro-powder abrasives and grease. During polishing, the polishing wheel rotates at high speed. The polishing wheel (circumferential speed above 20 meters/second) presses against the workpiece, causing the abrasive to roll and micro-cut the workpiece surface, thereby obtaining a bright machined surface. The surface roughness can generally reach Ra0.63 ~ 0.01 micron; when using Non-greasy matting polish can be used to improve the appearance of shiny surfaces by matting them. The main purpose of rock thin section polishing is to polish the surface of the thin section smoothly and remove the scratches and mechanical damage layer on the surface, so as to ensure that the sample observed under the microscope has a clear rock structure morphology.

The Chinese patent discloses a polishing device, the publication number is CN 102756332 B. What it aims to solve is that when the polishing machine in the prior art is polishing, the surface of the polishing machine will be close to the surface of the mold, causing a large friction force with it. , the maneuverability during polishing is not strong, and the movement is slow. Because of the large friction, it is also easy to damage the mold surface, which puts higher requirements on the workers’ skills and quality. Sometimes in order to achieve the required surface quality, It is often polished multiple times, which increases the labor intensity of workers, and it is also difficult to replace the polishing discs of the polishing machine. This application solves this problem very well, but the polishing device is not convenient for polishing rock slices according to their size. Adjusting and fixing can easily cause the rock slices to shift their position during grinding and polishing.

Therefore, a rock thin section polishing device is needed.
