Every piece of gauge is made, its choice of material quality, will directly affect the size of the stability, so whether in the manufacture or purchase block rules, should consider the material carefully, the following are some important characteristics: (1) Its standard size and accuracy of the accuracy requirements, need to reach the specification standard above. (2) The standard size is not affected by the change of environment. (3) Wear resistance and anti-corrosion. (4) Need to be practical, such as shape, size, size, thickness, etc.
Manufacturing blocks of materials have the following types: Chromium carbide, tungsten carbide, alloy steel, stainless steel, quartz, and so on, but the manufacturers of the current manufacturers are mainly alloy steel, tool steel quality, its advantages are summarized in the lower (1) After hardening deformation small wear and stability. (2) Low price and easy machining.
