Combining the physical property differences of the two types of materials, this document analyzes the differences in the machining processes of instrument components from six major dimensions: overall process flow, core operations, cutting and grinding tools, machining parameters, post-processing, and quality control, while also providing a process table. I. Core Premise DifferencesMaterial NatureHigh-hardness ceramics (alumina…

In the semiconductor industry, high-hardness ceramics (Al₂O₃, SiC, Si₃N₄, etc.) primarily target “chamber interiors / moving parts / extreme operating conditions,” while granite focuses on “large bases / platforms / vibration isolation references,” forming a clear complementary division of labor. The following is a direct comparison from four aspects: performance, typical applications, machining and assembly,…
