I. Inspect Appearance (Most Intuitive)Water marks or damp stains appear on the surface.Local color darkens, becomeull, or mottles, looking significantly different from dry areas.If the stains reappear shortly after wiping dry, it indicates internal moisture return.Mold spots, white frost, or black ots appear.Black spots, white fuzz, or pale green mold grow on edges, corners, the…
I. Why Does Granite “Absorb Moisture and Mold”?Granite itself is non-absorbent and does not mold, but it has micro-pores.Moisture, oil stains, and dust enter the pores → forming stains, water marks, and mold spots.Humid environment poor ventilation → mold grows on the surface dirt layer. II. Moisture Prevention Measures (Solving the Root Cause) III. Mold…
Granite is becoming the ideal base material for CNC machine tools and robotic automation, thanks to its extreme thermal stability, superior damping and vibration reduction, long-term precisiotention, and low maintenance costs, perfectly matching the stringent requirements of high-end manufacturing for micron-level precision and long-term stability. I. Core Advantages (Compared to Cast Iron / Steel) IV….
Why are laser equipment retrofits and upgrades almost universally switching to granite bases now? I. Core Conclusion in O SentenceAs laser equipment advances towards higher precision, higher speed, and higher stability, metal bases become insufficient; granite is the natural optimal solution. II. 5 Real Reasons Laser Eqent Must Use Granite Bases (Industry Standard) III. Why…
Limitations and Challenges: Granite is not Flawless Although granite is an ideal material fthe bases of ultra-precision equipment, it still possesses certain inherent limitations that require attention during selection and use: Brittleness and Poor Impact ResistanceGranite’s high hardness coexiith its brittleness — its fracture toughness is only 0.5–1.0 MPa·m¹/², approximately 1/10 that of cast iroresulting…
In the field of ultra-precision manufacturing and metrology, equipment bases are not merely simple support structures, but the physi carriers of precision benchmarks—their performance directly determines the imaging resolution of optical systems, the accuracy of parameters in semiconductor inspection, and even the full lifecycle yield of core equipment such as lithogramachines and coordinate measuring machines….
Natural granite is the preferred structural material for semiconductor inspection platforms, with extensive mature applications in wafe inspection, optical inspection, CMM measurement, AOI/X-ray inspection, probe stations, and metrology equipment. The following are specific, verifiable industry cases: I. Wafespection and Metrology Equipment (Core Scenario) II. High-End Inspection Equipment (Lithography, X-ray, Laser Inspection) III. Packaging and Back-end…
