During inspection, steel plates, aluminum parts, and fixtures are pushed and pulled on the surface. Long-term high-frequency friction only produces extremely shallow, fine lines without damaging the reference flatness; cast iron platforms will wear down and sink over a large area after long-term dragging, leading to direct scrapping.<\/li>\n\n\n\n
CMM ruby probes and carbide probes continuously tap the surface. Repeated single-point impacts result in no pits or chipping; metal surfaces are prone to point-like depressions after long-term tapping, causing measurement deviations.<\/li>\n\n\n\n
In machining-accompanying CMM stations, workpieces carry steel chips and hard abrasives that fall onto the surface. After moving the workpiece, deep scratches are not easily formed; metal surfaces are extremely easy to be gouged by iron chips, and the repair cost is very high.<\/li>\n\n\n\n
Repeatedly wiping the reference surface with scouring pads, dust-free paper, alcohol, and cleaning agents will not wear down the polished layer; ordinary coated metal platforms will lose their coating and luster after long-term wiping, causing a rapid decline in accuracy.<\/li>\n<\/ol>\n\n\n\n
III. Surface Sealing and Polishing Process Further Enhances Wear Life
Multi-stage Ultra-precision Grinding Mirror Polishing
The working surface undergoes cross-grinding with 2000#\u20135000# diamond abrasives. The surface crystals are tightly compressed, making the surface dense and smooth with a low friction coefficient, reducing scratch damage.
Penetrating Sealing Protection Treatment
Silane sealant penetrates and cures within the internal micropores, forming a hard composite wear-resistant layer:
Blocks oil and cutting fluids from penetrating and expanding the pores;
Enhances the overall hardness of the surface layer and slows down frictional wear;
Prevents internal stone grains from loosening, falling off, and producing dust.<\/p>\n\n\n\n

Longer Accuracy Maintenance Period
Under the same usage intensity, the granite surface can stably maintain 00\/000 grade accuracy for 5\u201310 years; cast iron platforms will show large-scale wear after 2\u20133 years, and the flatness will exceed standards, requiring regrinding.
Low Repair Cost After Wear
Slight scratches and worn areas can be locally precision-ground and polished to restore original accuracy; cast iron wear can only be repaired by overall re-milling, which is time-consuming and expensive.
No Secondary Wear Caused by Metal Corrosion
Steel and cast iron rust when exposed to moisture, and rust particles will continuously grind and scratch the surface; granite does not rust, so there is no problem of rust dust exacerbating wear.<\/p>\n\n\n\n![\"\"](\"https:\/\/jtlcnc.com\/wp-content\/uploads\/2026\/07\/\u5fae\u4fe1\u56fe\u7247_20260710164015_162_182.png\")
