◆Integrated sleeve spindle, imported precision grade spindle bearings, and spindle servo motor drive are adopted to achieve high precision, high rigidity and speed stability. Heat sink type spindle box design with symmetrical reinforcement can effectively reduce the spindle temperature rise and increase the spindle stability and bearing life.
◆High rigidity, the bed is tilted at 30° or 45°, adopting high-quality cast iron resin sand moulding and compact ribbed plate structure, which is of good rigidity and strong anti-vibration. The large drag plate and tool holder are inclined, which makes the machine easy to operate and chip removal, and occupies a small area with good livability.
◆The two-axis rotation is directly connected by servo motor and precision ball screw through elastic coupling, which has good stress condition and high positioning accuracy, and is equipped with computerised automatic lubrication system to forcefully lubricate the linear guide and ball screw.
◆ X-axis and Z-axis adopt high rigidity linear guideway, the track and the track are calculated to obtain better span, low resistance, high rigidity, high precision, the displacement speed can reach 28M/min, which improves the working efficiency and shortens the processing time.
◆ Hydraulic station adopts Taiwan variable pump, hydraulic motor, solenoid valve and air-cooling device, low noise and low oil temperature.
◆Totally enclosed protection, good waterproof, and the whole casting of the base.
