High-Hardness Ceramics vs. Granite (Precision Instrument Components) Pros and Cons ComparisonBoth are low-expansion, high-rigidity, wear-resistant, and non-magnetic precision base materials widely used in measurement platforms, machine tool beds, optical bases, and inspection fixtures. The core differences lie in physical properties, machinability, cost, and operating condition suitability. The following is a dimensional comparison and selection guide.I….

From raw blocks in the mine to precision mechanical components, the core process of granite is “mining → material selection → rough cutting → aging → precision cutting → CNC shaping → grinding and polishing → hole systems / inserts → inspection → protection”. Stress and precision are strictly controlled throughout the process, ultimately achieving…
