In order to manufacture the AKB series of machine, the manufacturing plant with a foundation of loading capacity of over 50 tons/m2 is required. We use 1.5m thickness of reinforced concrete to construct the foundation, which provides a heavy weight-resistant and extra stable assembly environment. In addition, the environmental temperature fluctuation may cause a thermal expansion and contraction effect on the machine structure. In order to ensure measuring accuracy, the factory temperature is controlled within ±1∘c with the use of air conditioning and humidity is controlled to under 75%.
