1、 Core of the plan
Marble platform drilling components achieve fixture installation, sensor fixation, and structural connection functions by processing threaded holes, through holes, or blind holes on the surface of natural granite or synthetic stone. This plan focuses on optimizing processing technology, controlling hole accuracy, and ensuring surface integrity to solve pain points such as brittle materials that are prone to edge breakage and difficult to process.
2. Applicable scenarios
Industrial testing platform: with threaded holes for installing fixtures (accuracy ± 0.02mm);
Precision machine tool worktable: through-hole design for vacuum adsorption or coolant circulation;
Semiconductor equipment base: blind hole embedded sensor (depth control ± 0.1mm).

Marble Longmen Component Solution
——High precision and high rigidity precision equipment core support
1、 Overview of the Plan
Marble gantry components (such as gantry bed, columns, and beams) are made of natural granite or artificially synthesized stone. With their high rigidity, low coefficient of expansion, and corrosion resistance, they have become an ideal choice for precision machine tools (such as gantry grinders and coordinate measuring machines). This plan focuses on material selection, manufacturing processes, and full lifecycle management to ensure that the gantry structure maintains a long-term precision of ± 0.005mm/m level.
2、 Core advantages
1. Breakthrough in material performance
• Natural granite (Jinan Green/Mount Taishan Green):
Hardness HS70-80, compressive strength 245-254N/mm ²;
The coefficient of thermal expansion is 8 × 10 ⁻⁶/℃, which is only one-third of that of cast iron;
Water absorption rate<0.13%, excellent corrosion resistance.
