The marble workbench is a precision reference measurement tool made of natural stone materials. It is an ideal reference surface for inspection of instrumentation, precision tools, and mechanical parts. Especially for high-precision measurement, due to its unique characteristics, the cast iron plate dwarfs. So what are the advantages of the marble workbench ? Next, take a look with Xiao Bian!
Marble table material characteristics
The marble workbench is a kind of granite slab, which is obtained from the high quality rock layer in the ground and made of high-quality "Jinanqing" stone by mechanical processing and hand-finishing. Black gloss, precision structure, uniform texture, good stability, high strength, high hardness, can maintain high precision under heavy load and general temperature, and has no rust, acid and alkali resistance, abrasion resistance, no magnetization, invariable type Etc. Granite slabs are suitable for measuring tools in mechanical factories. After hundreds of millions of years of natural aging, the form is extremely stable and there is no need to worry about deformation due to the normal temperature difference. After strict physical tests and selection of granite, crystal fine, hard texture, compressive strength of 2290-3750 kg / square centimeter, hardness of Mohs hardness of 6-7.
Marble bench advantages
1, good rigidity, high hardness, strong wear resistance, small temperature deformation.
2. After a long period of natural aging, the structure of the rock is uniform, the linear expansion coefficient is very small, the internal stress is completely disappeared, and the rock is not deformed.
3, not afraid of acid, liquid material erosion, will not rust, do not have to oil, easy to stick dust, maintenance, easy maintenance, long service life.
4, no scratches, not subject to constant temperature conditions, at room temperature can also maintain the accuracy of temperature measurement.
5, no magnetization, smooth movement can be measured, no sense of stagnation, not affected by the humidity, the plane is set well.
6, very resistant to wear, acid, alkali, a high degree of corrosion resistance, will never rust.
The above is a description of the relevant contents of the marble workbench and I hope to help you. For more knowledge about marble, please continue to pay attention to information on this site.
