The granite gantry structure simplifies complexity, reduces vibration, improves precision, and delivers superior performance. Our advanced granite technology will help you elevate your manufacturin.<\/p>\n

1. Semiconductor and Wafer Manufacturing: As ultra-stable bases for lithography machines, wafer inspection equipment, and wafer thinning 2. Precision Metrology: Support frames for Coordinate Measuring Machines (CMM), Video Measuring Machines (VMM), and laser interferometers. 3. Motion Control Systems: Tng platforms of air-bearing stages utilize the extremely high surface flatness of granite to achieve frictionless motion. 4. Aerospace and Optics: Large-scale aerospace component inspection platfoand high-end optical platforms (optical tables).<\/p>\n

1. Excellent dimensional stability: After billions of years of natural aging, internal stresses are fully released, ensuring stability and preventing deformation during long-term use.
\n2. High vibration damping: Its natural damping performance is over 10 times faster than cast iron, enabling rapid absorption of micro-vibrations generated by mechanical motion.
\n3. Low cot of thermal expansion: It is extremely insensitive to temperature fluctuations, ensuring consistent geometric precision across different environments.
\n4. Advanced customization:
