Application of Granite Base for 2D Vision Measuring Machines
The granite (Grade 00 Jinan Green natural) base is the core reference load-bearing component of 2D\/2.5D vision measuring machines. Relying on its low expansion, high rigidity, non-magnetic and wear-resistant properties, it provides a constant reference for optical non-contact measurement. Its applications are divided into three major sectors: equipment structural functional applications, subdivided industry quality inspection, and derivative expansion applications.
Fully Automatic 2D Vision Measuring Machine with Granite Base
I. Core Functional Applications of the Equipment Body (Basic Role of the Base)
. Overall Machine Rigid Load-Bearing, Suppressing Vibration Errors
As the base of the entire machine, it supports the XY stage, column, optical lens, and servo transmission system the high-density granite has a heavy self-weight and high damping, so workshop floor vibrations and machine tool impacts will not be transmitted to the measurement optical path, avoiding edge point deviations caused by lens shaking. The repeatability of fully automatic models during high-speed reciprocating motion is stable within \u00b11.5\u03bcm.<\/p>\n\n\n\n

    \n
  1. Constant Temperature Stable Reference,ating Temperature Drift
    The linear expansion coefficient of granite is only 1\/3 that of steel, resulting in minimal thermal deformation during temperature fluctuations; a temperature difference of 5C in ordinary metal bases will cause micron-level dimensional shifts. Under a workshop temperature difference of \u00b15~8\u00b0C, the annual accuracy drift of the granite base is \u2264.5\u03bcm, eliminating the need for frequent downtime for calibration and making it suitable for production workshops without strict constant temperature control.<\/li>\n\n\n\n
  2. High-Precision Planar Reference, Coordinate Perpendicularity
    The upper surface of the base is precision-ground to Grade 00, with flatness, straightness, and perpendicularity reaching metrology-grade standards XY linear guides and grating scales are directly installed on the granite base surface, ensuring the orthogonal accuracy of the X\/Y axes. Even if the workpiece is not precisely aligned, the of geometric tolerances (concentricity, parallelism, angle) remains accurate.<\/li>\n\n\n\n
  3. Integrated Wear-Resistant and Corrosion-Resistant Worktable
    The base integrates the workpiece surface with a Shore hardness of Hs70 or above, making it resistant to scratches from slight bumps of workpieces and fixtures; it is acid- and alkali-resistant, nonmagnetic, and does not generate static electricity, making it suitable for inspecting workpieces with cutting fluids or chemical solvents after cleaning, without attracting metal debris that would interfere with optical imaging<\/li>\n\n\n\n
  4. Long-Term Anti-Aging and Non-Deformation
    Natural granite undergoes natural aging and artificial stress relief treatment, exhibiting no metal fatigue or creep; the reference plane the equipment does not warp after 5 to 10 years of use, compared to cast iron bases which deform after 2 to 3 years, significantly reducing the cost of repair and regrinding.<\/li>\n<\/ol>\n\n\n\n

    II. Precision Quality Inspection Applications Across Industries (Implementation Scenarios After Equipping with Imaging Systems)<\/p>\n\n\n\n

      \n
    1. 3 Electronics Industry (Largest Usage)
      PCB Circuit Boards, FPC Flexible Boards: Measuring line width, pad hole diameter, positioning hole location, and board thickness tolerance; granite is electrostaticfree, preventing breakdown of tiny circuits and avoiding dust adsorption that blocks the optical path.
      Mobile Phone \/ Tablet Components: Middle frames, camera decorative rings, connectors, die-cut; micron-level contour, chamfer, and gap detection; stable and error-free batch first-article \/ patrol inspection.<\/li>\n\n\n\n
    2. Precision Molds and Hardware Stamping
      \/ Die-casting Mold Cavities, Punches, Inserts: Detecting cavity contours, arc R angles, step heights, and hole concentricity; the base is resistant to corrosion workshop oil and coolant environments, ensuring long-term \u00b12~5\u03bcm mold tolerance detection requirements.
      Precision Stamped Parts, Springs, Pins, Miniature Gears: Batch dimensions burrs, and contour comparison.<\/li>\n\n\n\n
    3. New Energy Industry
      Lithium Battery Electrodes, Tabs, Busbars: Tab spacing, electrode length and width, cutting edge dimensions;-contact optical measurement does not damage thin electrodes; the base is anti-static, eliminating the risk of electrostatic breakdown of battery cells.
      New Energy Vehicle Precision Components: Motor, seals, plastic housings, stamped sheet metal form and position tolerance detection.<\/li>\n\n\n\n
    4. Semiconductor and Optical Components
      Wafer Carriers, Lens Brackets, Optical Filters, Miniature Sensors Non-magnetic properties do not interfere with chips and optical components; low expansion ensures sub-micron measurement accuracy for tiny components.<\/li>\n\n\n\n
    5. Medical Device Precision Parts
      Surgical Instruments Miniature Implants, Medical Plastic Accessories; the base is resistant to disinfecting acidic and alkaline liquids, and the non-metallic material prevents metal precipitation contamination, meeting medical clean inspection environment requirements<\/li>\n\n\n\n
    6. Aerospace Precision Small Parts
      Aircraft Fasteners, Blade Small Parts, Aviation Gaskets; extremely high requirements for dimensional stability; the granite base eliminates measurement deviations caused by temperature, ensuring the consistency of aviation parts.<\/li>\n\n\n\n
    7. Watch, Plastic, and Touchscreen Industries
      Miniature Watch Movement Parts, Touchscreen Bezels, Injection-moldedlucent Parts; rapid batch detection of tiny arcs, narrow slots, and thin plastic part contours.<\/li>\n<\/ol>\n\n\n\n

      III. Derivative and Extended Application Scenarios
      2.5D \/ Composite Measurement Equipment
      The base is equipped with a Z-axis and laser head, upgrading it to 2.5D to simultaneously measure 2D profiles height and flatness, with the granite reference ensuring the unification of 2D and3D data.
      Automated Online Inspection Line Base
      Gantry-type long-stroke vision system complete granite base crossbeam, interfacing with the production line for automatic loading unloading, 24-hour continuous batch inspection, and resistance to continuous workshop vibration.
      Metrology Room Standard Calibration Platform
      The standalone granite base can serve as a met reference table for calibrating calipers, projectors, and standard gauge blocks, acting as a carrier for laboratory metrology standards.
      Non-standard Automated Vision Equipment Base
      Support base for inspection machines, laser marking positioning platforms, and dispensing machines, utilizing the high stability characteristics of granite to ensure vision positioning accuracy.
      IV. Summary of Application Advantages Compared to Metal BasesTable
      Performance Dimension Application Value of Granite Base Shortcomings of Cast Iron \/ Steel Base
      Temperature Stability Usable under workshop temperature differences, requires less calibration Even slight increases cause measurement drift
      Vibration Resistance Stable measurement next to production lines and machine tools Easily affected by vibration interference, large repeatability error
      Environmental Adaptation Oil-, acid\/alkali-resistant, static-free, non-magnetic Prone to rust, magnetic properties attract metal chips
