2D CNC offers Wele MG and MG-U moving gantry machining centres

The extensive range of Wele MG and MG-U (Universal) high capacity, moving gantry multi-purpose machining centres offers a XYZ maximum working volume up to 20,000 by 5,000 by 1,400 mm. Tables are up to 16,000 by 4,800 mm and are able to accept loads up to 2,500 kg/m2.

Available through 2D CNC Machinery, the two largest variants of the Wele MG and MG-U, designated 1650, have a high rigidity build standard with a shipping weight of some 148 tonnes. While the MG has an automatic multi-head exchange capability, able to store up to five units on the machine, the MG-U incorporates an AC tilting head giving full 5-axis simultaneous operation. The standard BT50 spindle is 35 kW, with 740 Nm of torque available through a two-stage gearbox giving 10 to 6,000 rpm. There are further speed options of 4,000 or 8,000 rpm or a direct drive Fanuc built 23 kW unit having a maximum speed of 10,000 rpm. Each slideway is equipped with ultra-heavy precision roller linear guideways and the twin-synchronised servo motor drives on the X-axis incorporate a Wele patented backlash elimination system. Linear scales ensure positioning accuracy of ±0.025 mm over the full travel with a repeatability of ±0.010 mm. Rapid traverse rates in X are 10 m/min and 12 m/min in Y and Z. Control options are Fanuc 18iM or Heidenhain iTNC 530 with fourth axis preparation and CNC rotary table options. There is a choice of a swing-type or hanging style operator panel with the addition of a portable 3-axis remote unit with handwheel.
