Overview
Granite V-block is a precision reference measuring tool made of stone material, which is an ideal reference surface for the inspection of instruments, precision tools, and mechanical parts. Granite (marble) V-block is especially used for high-precision measurement.
Product Details
Granite V-shaped blockThe "Jinan Green" granite material is processed by machinery and finely ground by hand. Black luster, precise structure, uniform texture, good stability, high strength, high hardness,Granite V-shaped blockAnd it has the advantages of high precision, no rust, acid and alkali resistance, non magnetization, invariance, good wear resistance, etc. It can maintain stability under heavy loads and general temperatures.
Granite V-block is a precision reference measuring tool made of high-quality stone material, which is an ideal reference surface for the inspection of instruments, precision tools, and mechanical parts, especially for high-precision measurement.
Granite V-shaped blocks are made from underground rock layers and have undergone billions of years of natural aging. Their shape is stable and there is no need to worry about deformation due to conventional temperature differences. The granite material selected through rigorous physical testing is finely crystallized and has a hard texture. Due to its non-metallic nature, granite has no magnetic reaction or plastic deformation. Its hardness is high, therefore it has good accuracy retention. Even if the granite V-shaped block is bumped by heavy objects during use, at most a few pieces of gravel will fall off.
Granite V-shaped blocks are superior to precision measurement reference parts made of cast iron and steel, and can achieve high and stable accuracy. Our company producesMarble V-shaped blockAfter being stored for a year, it can still maintain its original accuracy.
