Granite V-shaped Frames
Purpose of Moorstone V-shaped Frame: It is a kind of device used for supporting cylindrical workpieces such as bearings, pipes and sleeves and making the axial lines of the workpieces parallel to the working face of the platform so as to realize spotting and marking off. It is made by machining and manual grinding of good-quality “Jinan Qing” natural moorstones. It has the features of black color, precision structure, uniform texture and good stability and the advantages of high precision, no rustiness, acid-alkali resistance, no magnetization, no deformation, etc. It can keep stable under heavy load and at ordinary temperature.
The moorstone V-shaped frame draws materials from good-quality underground lithospheres, they are naturally aged for hundreds of millions of years, and their state is quite stable, so that you should not worry about the deformation of the moorstone V-shaped frame under the ordinary temperature difference. The moorstones undergoing strict physical tests and selection have dense crystallization and hard texture. Because they are non-metallic materials, the moorstones are free of magnetized reaction and plastic deformation.
Compared with precision measurement norm parts made of good-quality cast iron and steel, the moorstone V-shaped frame has high and stable precision. The marble V-shaped frame manufactured by our company can still keep the original precision after it is not used for one year.
