Specialized Marble Platform for Semiconductors (Core: High Stability Anti-static Nanometer Precision)Marble platforms for semiconductors (mostly natural granite / Jinan Green) serve as the core bases for lithography machines, wafer inspection, die bonding / dispensing, and etching / deposition, responsible for “locking in” precision and stability in nanometer-scale processes. I. Core Materials (Semiconductor Grade)Material: Jinan Green…
Ensuring the quality of the production process for precision granite components centers on establishing a full-process, traceable, and closed-loop quality control system. From the source to delivery, the requirements for “precision, stability, and consistency” must be implemented in every process. Below is a ready-to-implement quality assurance plan. I. Source Quality Control: Raw Material Inspection (Preventing…
Optimize the production process of precision granite components, with the core objective of improving stability, reducing costs shortening lead times, and minimizing scrap while ensuring precision. Systematic optimization can be carried out from five dimensions: source control, process upgrading, precision closed-loop, efficiency improvement, and assurance. Below is a practical optimization plan. I. Source Control: Reducing…
С учетом общеотраслевых стандартов, технологических процессов обработки и эксплуатационных требований к пятиосевым сверхточным станками уровни точности подразделяются на три основные категории: базовая геометрическая точность, допуски на форму и положение, а также качество поверхности. Эти уровни далее различают показатели для этапов черновой, прецизионной и сверхточной шлифовальной обработки, одновременно обозначая общепринятые отраслевые пороговые значения. Уровни точности обработки…
Combining the machining characteristics of five-axis ultra-precision machine tools with the advantages of granite bases—high vibration damping, low thermal deformation, high rigidity, and long-term accuracy stability—the core application areas are categorized, and the corresponding machining objects and working condition characteristics are explained:Application Areas of Granite Bases for Five-Axis Ultra-Precision Machine ToolsI.

In the micron-level machining of semiconductor ceramic substrates and structural ceramic parts, the machine bed is stable foundation and the guide rails are the lifeline—together they determine the rigidity, vibration resistance, and thermal stability of the engraving and milling machine, directly locking in ±0.01mm precision, and can be called the “anchor” of equipment accuracy. I….
In high-end fields such as semiconductor equipment, precision machine tools, metrology and testing, and optical instruments, large integrated bases, load-bearing platforms, and vibration-isolating benchmarks are the foundation of overall machine precision. With comprehensive advantages such as high damping, low thermal expansion, high rigidity, long-term dimensional stability, and the ability to be molded into ultra-large integrated…
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,…
