Rock box

The material of the rock square box is Jinan blue,and the rock 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 the workpiece and equipment installation.It is a benchmark measurement tool made of stone materials,which is an ideal reference plane for the inspection of instruments,tools,and mechanical components.Rock boxes are especially used for measurement purposes.The rock 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.

Application of Rock Box:

The rock box is used to detect the flatness and verticality of components,workpieces,machine tool workbenches,guide rails,and work.

The rock 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.

Material selection of rock box:Granite material that has undergone strict physical testing and selection,with fine and dense crystals and 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.

Measurement of rock box:Even if it is hit by heavy objects during use,at most a few pieces of stone debris will be dropped.The rock box is superior to the measurement reference parts made of cast iron and steel,and can achieve high and stable accuracy.
