Granite Surface Plate Marble Inspection Measurement Working Platform

A Granite Surface Plate Marble Inspection Measurement Working Platform is a platform made of fine-grained,structurally dense pyroxene,diabase,granite,or other rocks that meet the requirements.The requirements for rocks can be found in the section on rock rulers.Marble platforms can also be made into square,rectangular,or circular shapes.Compared with cast iron flat plates of the same specifications,the structure of Granite Marble Platforms is simpler.Cast iron flat plates can be cast into box type or ribbed plate structures,while Granite Marble Platforms only have solid structures,.The specifications of the Granite Marble Platform are two less than those of the cast iron flat plate,namely,there are no 8mx8om and 1250mm1250mm.The basic dimensions and allowable deviations of other specifications are exactly the same as those of the cast iron flat plate.However,the thickness H of the Granite Marble Platform is smaller than that of the cast iron flat plate.The accuracy level of the rock flat plate is divided into four levels:000 and 1.The tolerance values and calculation formulas for flatness at all levels are also the same as those for cast iron rulers.

Rock slabs of various specifications have the same concentrated load area,rated load applied,and allowable deflection value in the center of the working face as cast iron slabs.The surface roughness R of the stone slab working face is 0.32m0.63m.Natural colored stripes and spots are allowed on the working surface of the Granite Marble Platform,and there should be no cracks,dents,loose tissue,scratches,abrasions,burns,or other appearance defects that affect its use.The purpose of a Granite Marble Platform is the same as that of a cast iron flat plate,mainly used for inspection.There are few Granite Marble Platforms in the production site(workshop),and only a few enterprises have rock flat plates in their measuring rooms.The vast majority of coordinate measuring machines have rock workbenches,and other instruments,such as roundness meters,also have rock workbenches,most of which are black rocks.Maintain the rock slab according to the method of maintaining cast iron slabs,but do not apply rust proof oil.Marble platforms are more afraid of being bumped by hard objects.

Characteristics and advantages of Granite Surface Plate Marble Inspection Measurement Working Platform

1.The Granite Marble Platform has a dense organizational structure,smooth surface,and low roughness values;

2.After long-term aging,the internal stress of marble disappears,the material is stable,and it will not deform;

3.Marble platform is resistant to acid,alkali,and magnetism;

4.The Granite Marble Platform will not get damp or rust,and is easy to use and maintain;

5.The Granite Marble Platform has a low coefficient of linear expansion and is less affected by temperature;

6.After collision or scratching,the working surface of the Granite Marble Platform will only produce pits,without any protrusions or burrs,and will not affect the measurement accuracy.
