Machine structure designed by Japanese professionals，Bed、Column、Saddle、Table，spindle head all adopt double-layer rib structure，improving machine vibration resistance，effectively enhancing overall rigidity and strength，stable without vibration during high-speed machining，ensuring high rigidity and machining precision。

All castings use high-strengthHT300A+cast iron (HT300A+)，all undergo stress relief annealing，ensuring long-term stability without deformation。Casting processed by Taiwanese and Japanese machines，rough and finish machining separated by time and sequence。guide surfaces finely ground and polished，stable machining precision。
