The granite slab is a precision reference measuring tool made of natural stone materials. It is an ideal datum for inspection of instrumentation, precision tools and mechanical parts. Especially suitable for high precision measurement.
Sharing the common sense of granite slabs Granite slabs can be damaged by heavy objects even when they are hit by heavy objects. The flat plate is superior to the precision measuring reference parts made of high-quality cast iron and steel for high and stable accuracy. The 1000×630mm '00' grade flat plate produced by this granite plate was tested and the original precision was maintained after one year of storage.
The granite slab is a precision reference measuring tool made of natural stone materials. It is an ideal datum for inspection of instrumentation, precision tools and mechanical parts, especially for high-precision measurement. The plate is made of high quality rock layers in the ground. After hundreds of millions of years of natural aging, the shape is extremely stable, so you don't have to worry about deformation due to the normal temperature difference. The granite plate is subjected to strict physical tests and selected granite materials, which are finely crystallized and hard. Due to the non-metallic materials of granite, there is no magnetic reaction and no plastic deformation. Granite slabs have high hardness and therefore good precision retention.
The granite plate has high precision, no rust, acid and alkali resistance, no magnetization, no change, and good wear resistance. Granite plates can be stable under heavy loads and normal temperatures. The rock has long-term natural aging, uniform structure, minimal linear expansion coefficient, complete disappearance of internal stress, and no deformation, so the precision is high, the rigidity is good, the hardness is high, and the wear resistance is strong.
We will introduce here first, and let Hebei Zhaoji Precision Mold Casting Tool Co., Ltd. share the knowledge of granite slabs with you next time.
