Feature 1: symmetrical structure, frame in frame structure and gravity center double drive mode are adopted to effectively improve the rigidity of the machine tool and suppress vibration.

Feature 2: improve the machining accuracy, improve the service life of machine tool and cutter, and enhance the reliability of machine tool.

Feature 3: it has the function of on-line programmable control of pushing and pulling force of workpiece, which can fully improve the internal prestress of workpiece, improve the processing accuracy of large thin-walled and slender parts and improve the processing yield.

Feature 4: equipped with direct drive swing angle milling head, larger torque, wider processing range and higher efficiency. Equipped with high torque and high precision b-axis, it has higher material removal rate than traditional machine.

Feature 5: it is equipped with programmable on-line control of the pushing and pulling force of the workpiece. The user can realize the dynamic servo control of the W-axis through the specific processing program instructions, so as to achieve the programmable control of the pre tightening pushing and pulling force of the workpiece during the part processing.

Feature 6: the tool is on three linear axes and the workpiece is on two rotary axes, with Zui excellent spindle support; The swing angle of axis B is ± one hundred and thirty °， C-axis continuous 360 ° Spin. The chain type tool magazine is integrated with the machine bed, with fast tool changing speed and high reliability.
