Granite V-shaped block

Granite V-shaped block is mainly used for testing, marking, calibrating and clamping in machining of fine shaft parts. Granite V-shaped block is a kind of stone that has been naturally aged for hundreds of millions of years. Its shape is extremely stable. There is no need to worry about deformation due to conventional temperature difference. It is selected through strict physical tests. Granite stone has fine crystallization and hard texture, which is suitable for the inspection of meticulous tools and the measurement with appropriate accuracy

granite V-shaped block is a kind of marble measuring tool for detecting cylinders. It is manufactured according to Jiayuan gb4972-85 standard. It is generally supplied in pairs. It is a quadrangular body, four working surfaces or four 90 degree grooves with different sizes

granite V-shaped block is mainly applicable to the inspection and marking of shaft parts, shaft inspection, correction, marking, and also to the inspection of workpiece perpendicularity and parallelism

granite V-shaped blocks are generally supplied in pairs, which are a tetrahedron, four working surfaces or four 90 degree grooves with different sizes. It is mainly applicable to the inspection and scribing of shaft parts, shaft inspection, correction, scribing, and also to the inspection of workpiece perpendicularity and parallelism

granite V-shaped block is used to check the concentricity of various shafts, and is used for high sizing blocks such as fine marking and assembly. V-shaped iron and V-shaped frame are divided into one slot and four slots, with pressing plate type and basket type with horseshoe shaped hoop frame

granite V-shaped block is used to check the measurement benchmark, check the dimensional accuracy or shape deviation of parts, and make tight lines. It is also an important basic tool in mechanical manufacturing

the purpose of granite V-frame: it is a tool used to support cylindrical workpieces such as shafts, tubes, sleeves, etc., so that the axis line of the workpiece is parallel to the working surface of the platform, so as to align and scribe. The granite V-shaped frame is made of "Jinan green" naturally growing granite through mechanical processing and manual fine grinding. With black luster, fine structure, uniform texture and good stability, granite V-shaped frame has the advantages of good accuracy, non rusting, based on actual reports, non magnetization, constant type, powerful, etc. It can maintain stability under heavy load and general temperature
