Granite slotted platforms are high-precision reference measuring tools made from natural granite through machining and hand-polishing. They offer exceptional stability, wear and corrosion resistance, and are non-magnetic. They are suitable for high-precision measurement and equipment commissioning in fields such as machinery manufacturing, aerospace, and electronic testing.
Mineral composition: Primarily composed of pyroxene and plagioclase, with minor amounts of olivine, biotite, and trace amounts of magnetite. Years of natural aging result in a uniform microstructure and the elimination of internal stresses, ensuring long-term deformation resistance.
Physical Properties:
Linear expansion coefficient: As low as 4.6×10⁻⁶/°C, minimally affected by temperature, suitable for both constant and non-constant temperature environments.
Compressive strength: 245-254 N/mm², Mohs hardness of 6-7, and wear resistance far exceeding that of cast iron platforms.
Corrosion resistance: Acid and alkali resistant, rust-resistant, low maintenance, and a service life of decades.
Application Scenarios
Mechanical Manufacturing, Workpiece Inspection: Checks the flatness and straightness of machine tool guideways, bearing blocks, and other components, maintaining an error within ±1μm. Equipment Debugging: Serves as a reference platform for coordinate measuring machines, ensuring measurement data accuracy.
Aerospace Component Calibration: Checks the form and position tolerances of high-temperature alloy components such as aircraft engine blades and turbine disks. Composite Material Inspection: Checks the flatness of carbon fiber composite components to avoid stress concentration.
Electronic Inspection, PCB Inspection: Serves as a reference platform for inkjet printers, ensuring a print position accuracy of ≤0.05mm.
LCD Panel Manufacturing: Checks the flatness of glass substrates to prevent abnormal liquid crystal molecular alignment.
Easy Maintenance: Resists dust and requires no oiling or maintenance. Daily maintenance is simple; regular cleaning is all that’s needed to keep it in good working condition.
