Core Requirements:<\/strong> Excellent vibration isolation, non-magnetic, extremely low coefficient of thermal expansion.<\/p>\n\n\n\n

| Core Dimension | Recommended Configuration | Selection Rationale |
| :– :— | :— |
| Material Grade | Jinan Green (Pure black glossy finish, fine grain) | High damping coefficient; vibration damping effect is 3-5 times that o effectively absorbing micro-vibrations from laser equipment or precision instruments. |
| Precision Grade | Grade 000 (Ultra-High Precision Grade) | Optical positioning requs sub-micron accuracy; Grade 000 flatness (\u22643.5\u03bcm\/m\u00b2) is the standard for high-end optical experiments. |
| Surface Treatment | Precisionding Hand Lapping | Surface roughness can reach Ra 0.1\u03bcm, smooth as a mirror; it is not only aesthetically pleasing but also ensures the fil components. |
| Special Requirements | Temperature Adaptation | Select varieties with extremely low expansion coefficients to ensure platform dimensions remain precise despite workshop temperature and humidity fluctuations. |<\/p>\n\n\n\n

\ud83d\udca1 Professional Selection Tips<\/p>\n\n\n\n

    \n
  1. Regarding Dimensions: The standard size library is limited. If standard sizes are insufficient, custom processing is the preferred choice. Please reserve positions for T-slots, holes, or lifting holes during processing.<\/li>\n\n\n\n
  2. Regarding Color Variation: Jinan Black and Mount Tai Black have distinct appearances; Jinan Black is darker and glossier, suitable for optics\/instruments, while Mount Tai Black is grey-black and suitable for heavy-duty machine tools.<\/li>\n\n\n\n
  3. Shipping & Installation: Large platforms require anti-collision treatment (corner protection) before leaving the factory. During installation, be sure to use leveling bolts in conjunction with a level to ensure proper leveling, which will benefit you for a lifetime.<\/li>\n<\/ol>\n\n\n\n
