The hardness of tooling fixtures is generally divided into:

Cushion blocks, pins and the like are generally harder, and the hardness is: HRC 55-60

Others For auxiliary flat plate tempering, select hardness HRC27-32.

Tooling, that is, process equipment: refers to the general term for various tools used in the manufacturing process. Including cutting tools/jigs/molds/measuring tools/inspection tools/auxiliary tools/fitter tools/station equipment, etc. Workwear is its general abbreviation.

The fixture is a process device used to quickly fasten the workpiece during processing and maintain the correct relative position of the machine tool, tool, and workpiece. In other words, Workholding fixtures are indispensable components for mechanical processing. Driven by the development of machine tool technology in the direction of high speed, efficiency, precision, composite, intelligence, and environmental protection, fixture technology is moving towards high precision, efficiency, modularity, combination, and universality. , economic direction development.
