Description

TECHNICAL FIELD

[0002] A thermal simulation testing machine is a physical simulation testing device, which reproduces the physical process of a small sample on the testing device in the process of material preparation or thermal processing, and fully and accurately exposes and reveals the change rule of the organization performance of the material in the thermal processing process. One type of single-axis compression experiment is selected, and the small sample is in a cylindrical shape, and the diameter of the bottom surface of the cylinder is not equal to phi 6-phi 10 mm.

[0003] In the prior art, a considerable part of the cylindrical sample is cut by wire cutting, and this processing procedure has certain advantages compared with turning processing procedure, but the sample surface is accompanied by a wire cutting affected layer and a cooling liquid residue. The cooling liquid can be removed by a cleaning agent, but the wire cutting layer must be removed by sandpaper. In addition, the sample often has surface oxidation and corrosion due to poor storage environment, and must be removed clean before detection in order to obtain good experimental results. In order to remove these surface oxidation and corrosion layers, a direct operation method is to use manual holding grinding, which not only has safety hazards, but also is difficult to ensure uniform grinding of the sample outer circle, thereby causing uneven deformation of the sample during subsequent simulation experiment, and the grinding efficiency is low.
