Large measuring machine assembly plant Overview • Manufactured models: large coordinate measuring machines, FPD-related equipment • Environment, manufacturing facilities Assembly environment: 20 °C ± 1 °C Grade slab: 1 m 20-ton cranes: 3 • Number of manufactured units: 100 machines per month Main facilities • Air-conditioning: Our delivent fan system suppresses variation in the room temperature as much as possible. • Lighting: We use highly efficient lights whose brightness is controlled using inverters to conserve energy. Our system suppresses the initial illuminance, gradually increases the supplied power, and maintains a constant illuminance of 650 to 700 lux.
