Precision Granite V-Block: Natural Black Stone, 00 Grade Accuracy

The precision granite V-block is an indispensable three-dimensional measurement reference tool in industrial production. It provides a stable and reliable three-dimensional coordinate benchmark for inspecting various complex components through six high-precision working surfaces that are mutually perpendicular.
Product Advantages:
1.Extremely Precise: The six working surfaces have undergo extremely precise production grinding and production and are extremely perpendicular and parallel to each other, providing stable and accurate three-dimensional benchmarks.
2.Long-lasting and durable: Made of natural black granite, the material is extremely stable and is hardly to be affected by temperature changes, maintaining its accuracy over a long period. The surfaces of the V-block is hard and wear-resistant, and is not prone to scratches.
3.Extensive applicability: Due to its non-magnetic and non-conductive properties , the granite V-blocks
particularly suitable for inspecting magnetic parts or precision electronic components without causing interference.
4.Simple maintenance: Since the granite V-block does not rust and is resistant to corrosion, it only requires simple daily wiping and cleaning. There is no need to apply anti-rust oil, saving on maintenance costs.

Precision Specifications: Taking the precision granite blocks offered by Shandong Sincere Precision Machinery Company as an example, the working surfaces are processed through scraping or precise grinding techniques, achieving precision levels such as Grade 0 and Grade 00. Key precision indicators include the flatness of the working surfaces, the parallelism of adjacent surfaces, and the perpendicularity of relative surfaces. For instance, a 100×100×100mm Grade 00 product has a flatness tolerance of 1 micron (0.001mm).
