Key Differences Between Marble Platforms and Cast Iron Platforms
1.Material and Stability
Marble Platform:Made of natural granite,it does not deform,does not rust,is resistant to acids and alkalis,has minimal thermal expansion and contraction,and maintains extremely high precision.
Cast Iron Platform:Made of cast iron,it is prone to rust,susceptible to moisture and impacts,and easily deforms under heat/stress,causing a gradual decrease in precision.
2.Precision and Applications
Marble Platform:Higher precision(000,00,0 grade),mostly used for precision testing,scribing,benchmark measurement,and instrument platforms.
Cast Iron Platform:Generally lower precision,mostly used for welding,assembly,tooling,scribing,and other scenarios where extremely high precision is not required.
3.Surface and Maintenance
Marble Platform:Smooth and delicate surface,requires no oiling,does not attract iron filings,simple maintenance,and remains clean and tidy.
Cast Iron Platform:Requires regular rust prevention and oiling;the surface easily attracts dust and iron filings,making cleaning difficult.
4.Durability
Marble Platform:High hardness,wear-resistant,and maintains stable precision even after decades.Cast iron platforms are prone to wear and deformation,and their precision will deteriorate after a few years of use,requiring re-scraping.
