Granite flat plates

Granite flat plates are benchmark measuring tools made of stone materials,which are ideal reference surfaces for the inspection of instruments,tools,and mechanical components.Especially in terms of measurement,due to its characteristics,cast iron flat plates pale in comparison.Granite is sourced from underground rock layers and has undergone natural aging for billions of years.Its shape is extremely stable and there is no need to worry about deformation due to conventional temperature differences.The granite material,which has undergone strict physical testing and selection,is finely crystalline,hard in texture,with a compressive strength of 2290-3750 kg/square centimeter and a hardness level of 6-7 Mohs hardness.Extremely damaged,acid resistant,alkali resistant,highly resistant,and will not rust.Due to the non-metallic nature of granite materials,magnetic reactions occur and there is no plastic deformation.Its hardness is 2-3 times higher than cast iron(equivalent to HRC>51),so its accuracy retention is good.In use,even if a rock tool is hit by a heavy object,at most a few pieces of debris will be dropped,and it will not damage accuracy due to deformation like metal tools.It is superior to measuring reference parts made of cast iron and steel,and can achieve high and stable accuracy.

Granite flat plate,granite flat plate,granite inspection flat plate,instrument platform,made of"Jinan Qing"stone material through mechanical processing and manual precision grinding.Black luster,structure,uniform texture,good stability,high strength,can be maintained under heavy loads and general temperatures,and has advantages such as non rusting,non magnetization,and unchanging shape.Granite flat plates are suitable for measuring tools in mechanical factories.

Design requirements for granite slabs:

The technical requirements for the design of granite slabs are generally based on the JB/T 7974-2000 Mechanical Industry Standard of the People's Republic of China.The technical requirements for the design and production of granite slabs should also be specified according to actual needs.In the standards,enterprise standards,and usage requirements for granite slabs,requirements can be made for the design and production technology of granite slabs according to actual needs.The design and production of granite slabs should be based on the principle of producing good products at low cost.

During the production process of granite slabs,there may be some theoretical weight errors,but it should be noted whether the production errors of granite slabs affect their normal use.The design of general granite slabs should consider the errors in mechanical processing and casting.The weight error of granite slabs should generally not exceed 10%.When it exceeds 10%,we need to further evaluate and inspect the quality of granite slabs to determine whether they can be put into use normally.

During the production process of granite slabs,there may be some product defects,which can be remedied and repaired by adopting the correct process methods.
