It is of semi closed loop vertical machining center with X, Y, Z axis controlled by servo motor directly. The three axis are all the steel ball rolling linear guide rail which is large load capacity, wide span and high precision. XY axis is 35mm overloading and Z axis is 45mm overloading .Compact and reasonable structure and dimensions. Spindle is driven by servo motor through synchronous belt. It can finish clamping one-time of various dishes, plates, shell, cam, mold and other complex parts. It can complete the drilling, milling, boring, reaming, expansion, and other rigid tapping process . so it is suitable for many varieties, medium and small batch production. It can finish the processing of complex, high precision parts . It can be matched the four rotary shaft , in order to meet the requirements of special parts.
