Marble testing platform is a high-precision measuring tool mainly used for the inspection and measurement of instruments and mechanical parts. It is a precision benchmark measuring tool made of natural stone materials, mainly used for industrial production and laboratory measurement work.
The main mineral components are pyroxene, plagioclase, a small amount of olivine, biotite, and trace magnetite, usually with a black luster. It has fine crystals, a hard texture, a compressive strength of 2290-3750 kg/cm2, and a hardness of 6-7 on the Mohs scale.
feature
Stable accuracy: After long-term natural aging, the internal stress of marble disappears, the material is stable, and it is not easily deformed. Its organizational structure is dense, the surface is smooth and wear-resistant, and the roughness value is small. After collision or scratch on the working surface, only pits will be produced, without convex lines or burrs, which has no impact on measurement accuracy.
Easy maintenance: It has the characteristics of acid resistance, alkali resistance, corrosion resistance, and demagnetization resistance, will not be affected by moisture or rust, has a small coefficient of linear expansion, and is less affected by temperature.
Application field
Semiconductor and optical inspection: can be used for wafer inspection, optical component calibration, etc., often combined with air floating guides or vacuum adsorption systems, can achieve nanometer level positioning accuracy.
Mechanical processing inspection: As a reference surface for coordinate measuring machines (CMM), it can also be used for flatness and perpendicularity inspection of molds and precision parts.
Research and Laboratory: In the fields of materials science, biomedical science, etc., it can be used for high-precision experiments such as microscopy and cell sorting.
Platform inspection and cleaning
Check for cracks, dents, or impurities on the surface of the platform to ensure a smooth and flawless working surface.
Use a dust-free cloth dipped in 75% alcohol or neutral cleaner to wipe the surface, avoiding corrosive liquids.
routine maintenance
Cleaning and maintenance: Use a soft dry cloth to wipe the work surface to avoid scratches.
Moisture and dust prevention: When stored for a long time, apply a 1:1 diesel engine oil mixture and place it in a constant temperature and humidity environment.
Regular calibration: Check the levelness every 3-6 months and adjust deviations in a timely manner.
