Problems solved by technology

[0003] One is that the structure of a high-temperature vacuum friction and wear testing machine has changed greatly from the existing friction and wear testing machine and high-temperature friction and wear testing machine, which is not conducive to the integrated use of equipment. Multiple equipment is required to perform different tests, and the actual operation is extremely inconvenient , resulting in a serious waste of resources;

[0004] The second is that a high-temperature vacuum friction and wear testing ...
