Granite square box

Granite square boxes are benchmark measuring tools made of stone materials,which are ideal reference surfaces for the inspection of instruments,tools,and mechanical components.Granite square boxes are especially used for measurement purposes.The granite square box is taken from the underground rock layer,and after billions of years of natural aging,its shape is extremely stable,so there is no need to worry about deformation due to conventional temperature differences.

Performance of granite square box:

The granite material,which has undergone strict physical testing and selection,is finely crystallized and has a hard texture.Due to the non-metallic nature of granite materials,magnetic reactions occur and there is no plastic deformation.Therefore,the accuracy retention is good.

Precision of granite square box:

Even if it is hit by heavy objects during use,at most a few pieces of debris will fall off.The granite square box is superior to the measurement reference parts made of cast iron and steel,and can achieve high and stable accuracy.

Granite square box material:

Its material is Jinan blue,granite has a black luster,uniform structural texture,good stability,and high strength.The working surface adopts scraping or grinding technology,which is used to measure the straightness and verticality of workpieces and equipment installation.

Use of granite square box:

Check the flatness and verticality of components,workpieces,machine tool workbenches,guide rails,and work.The granite square boxes produced by our company have the advantages of non rusting,non magnetization,unchanging shape,and good quality.Can maintain stability under heavy loads and general temperatures.

Technical parameters of granite square box:

Granite square boxes are mainly used for checking the parallelism and verticality of components and supporting workpieces during marking.They are generally cubes or rectangles with the same side length.

The granite square box is mainly composed of pyroxene and plagioclase,with a black color and structure.

The granite square box cannot withstand excessive impact and impact,and the humidity should not be too high,otherwise it will deform.
