Ultra-Precision Granite Gantry Base

When demanding nanometer-level precision and high throughput, the material and manufacturing process matter most. Our gantry base offers distinct advantages over standard granite and metal solutions:

1. ZHHIMG® Black Granite: A Material Superiority

●   Exceptional Density: Unlike the common, lower-density granite used by many manufacturers (often compromised by cheaper alternatives like marble), ZHHIMG® utilizes a premium black granite with a high density of approximately 3100 kg/m³ This is superior to many European and American black granites.

●   Thermal Stability: The low coefficient of thermal expansion ensures minimal dimensional change due to temperature fluctuations, guaranteeing long-term accuracy, especially within our temperature-controlled environments.

●   Superior Dampening: The material's high internal friction provides exceptional vibration damping, effectively isolating the sensitive motion components (linear motors, air bearings) from environmental and operational vibrations.

2. Manufacturing Expertise for Ultimate Precision

●   World-Class Machining: Utilizing advanced equipment, including specialized Taiwan NANT Precision Grinders (valued over 500,000 USD per unit), we achieve machining capabilities for single components up to 20 meters in length and 100 tons in weight.
●   Metrology Guarantee: Our parts are finished in a dedicated 10,000 m² Constant Temperature and Humidity Workshop. This environment features an anti-vibration trench (500mm wide, 2000 mm deep) and a 1000 mm thick, ultra-hard concrete foundation, ensuring measurement integrity and zero ground vibration.
●   The Human Touch: Our core competency lies with our master craftsmen, many with over 30 years of manual lapping experience. They possess a legendary hand-feel capable of achieving nanometer-level flatness, often called the "Walking Electronic Level."
