1 min read
Wele MG and MG-U (Universal) high capacity, moving gantry multi-purpose machining centres have an XYZ working volume up to 20,000 by 5,000 by 1,400 mm. Tables are up to 16,000 by 4,800 mm and able to accept loads up to 2,500 kg/m2 of area.
Available through 2D CNC, the two largest variants, the MG and MG-U 1650, have a high rigidity build standard and have a shipping weight of some 148 tonnes. The MG has an automatic multi-head exchange capability and is able to store up to 5 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 the choice of a swing-type or hanging style operator panel with the addition of a portable 3-axis remote unit with handwheel. The tool magazine has 32 pockets as standard taking tools up to 215 mm diameter by 400 mm long.
Wele Mechantronic developed the machining centres in a strategic alliance within the JTEK Group. JTEK is owned by car-maker Toyota which also owns Mitsui Seiki and Toyoda Machine Tool.
