◆CNC turning and milling compound machine tool is a major model of composite processing machine tool, in addition to the function of CNC lathe, it can also complete plane milling, drilling, tapping, straight groove, spiral groove and milling gear, etc., with turning, milling and boring and other composite functions, this product has excellent material selection and strong structural rigidity; The use of conjoined castings, the bed supporting plate span is large, the tool holder is oblique, and it has the advantages of good chip removal capacity and operation convenience, high precision, strong stability, and small land occupation; Various brands of operating systems can be selected according to customer needs.
◆ Integral sleeve spindle, imported precision spindle bearing, and spindle servo motor drive to achieve high precision, high rigidity and speed stability. The heatsink headstock design and symmetrical stiffeners can effectively reduce the temperature rise of the spindle and increase the stability and bearing life of the spindle.
◆High stiffness, the bed is inclined at 30° or 45°, using high-quality cast iron resin sand molding, compact rib plate structure, good rigidity and strong shock resistance. The large carriage and the tool holder are obliquely positioned, which makes the operation and chip removal of the machine tool very convenient, and the footprint is small, and it has good pleasantness.
◆ The two-axis rotation is directly connected by the servo motor and the precision ball screw through the elastic coupling, which has good stress and high positioning accuracy, and is equipped with a computerized automatic lubrication system for the linear guide rail and ball screw.
◆ The X-axis and Z-axis adopt high-rigidity linear slide rails, and the better span between the tracks and the tracks is calculated to achieve low resistance, high rigidity, high precision, and the displacement speed can reach 28M/min, which improves work efficiency and shortens processing time.
◆ The hydraulic station adopts Taiwan variable pump, hydraulic motor, solenoid valve and air cooling device, which has low noise and low oil temperature.
◆Fully enclosed protection, good waterproofness, overall casting of the base.
◆ Taiwan eight-station hydraulic rotary turret is adopted, with high positioning accuracy, low failure rate, fast tool change, and nearby tool change.
◆ Servo spindle is adopted, and two (three) axes are installed with radial or axial servo power head, which can realize 360 degrees arbitrary indexing positioning of the spindle, and has the functions of side end drilling, tapping and milling, and can complete more complex parts processing at one clamping.
