Metal sample polishing and clamping device and manufacturing method thereof

Abstract

The invention discloses a metal sample polishing and clamping device and a manufacturing method thereof. The device is used for preparing a metal sample with the smooth surface, and comprises a shellwith an upper opening and a lower opening, a curable filling adhesive applied in the shell, and a magnet pre-buried in the curable filling adhesive, wherein a cavity with a top opening is formed in the curable filling adhesive above the magnet. The manufacturing method comprises the steps of placing a piece of plastic paper or a film on a flat tabletop; placing the sample needed to be polished onthe flat plastic paper or film; placing the magnet on the sample; covering the sample and the magnet with the shell; filling the shell of the sample polishing and clamping device with the curable filling adhesive; and after the curable filling adhesive is solidified, removing the plastic paper or the film, removing the sample, and removing the position after the sample to form the cavity. The device is simple in structure, convenient to use, easy to manufacture, low in manufacturing material cost and easy to realize, and is especially suitable for surface polishing treatment of metal samples with relatively small wall thicknesses or sizes.

Description

technical field [0001] The invention relates to a metal sample grinding and clamping device and a preparation method thereof, which are used for preparing a metal sample with a smooth surface, and are especially suitable for surface grinding treatment of thinner or smaller samples. Background technique [0002] The test of metal materials requires the surface of the test sample to have a high degree of smoothness. At present, there are two ways to prepare it by manual grinding and rotary table grinding machine. Manual grinding is time-consuming and labor-intensive, which takes up precious time of experimental researchers and seriously restricts the progress of experimental research. However, the use of rotary table grinding machine to grind samples is limited by its sample clamping method and sample size. Smaller samples must be passed through After inlaying, it is held and polished by hand, and inlaying will seal part of the surface of the sample, which is not feasible in m...

AI Technical Summary

Problems solved by technology

It is dangerous to hold the metal samples with thin wall thickness by hand, and it is very easy to hurt the fingers, and it is also difficult to hold the small samples themselves, and the samples are easy to fly out with the turntable during grinding; Small samples or samples with irregular shapes cannot be firmly adsorbed on the upper suction cup of the sample mill for grinding. Practice has proved that with the high-speed rotation of the turntable, smaller samples have a smaller contact surface with the upper suction cup. It often falls down, which poses a certain safety risk
