Keywords: Granite surface plate manufacturing, diamond grinding, vibration aging, automation
The production of granite surface plates involves rigorous multi-stage processes:<\/p>\n\n\n\n

    \n
  1. Raw Material Selection: Blocks are sourced from quarries with consistent mineral composition (typically 60-70% quartz, 15-20% feldspar, and <10% mica).<\/li>\n\n\n\n
  2. Coarse Shaping: Computer-controlled saws cut blanks to near-final dimensions, minimizing material waste.<\/li>\n\n\n\n
  3. Precision Grinding: Diamond-impregnated wheels refine surfaces to micrometer-level tolerances. Automated systems employ laser interferometry for real-time flatness monitoring.<\/li>\n\n\n\n
  4. Vibration Aging Treatment: Post-grinding stress relief using resonant frequency vibration ensures long-term stability.<\/li>\n\n\n\n
  5. Final Lapping: Nano-abrasive slurries achieve mirror finishes (Ra < 0.2\u03bcm) critical for optical measurement applications.<\/li>\n<\/ol>\n\n\n\n

    Advanced facilities utilize robotic handling and AI-driven quality control, reducing human error. For instance, Botou Jingda’s automated line achieves 98% first-pass yield for Grade 00 plates.<\/p>\n\n\n\n
