Case studies
Wind tower flange Machining
A leading Australian wind tower manufacturer required the end flange of the tower to be machined within 1 hour and within a flatness tolerance of 0.30mm at 2.7m diameter. The fabrication required the WP4300 to clamp into the tower and machine the flange.
Location
Australia
Equipment utilised
Mirage WP4300 with strengthened base is used to mount into the tower fabrication flange and is locked in place using an eight jaw chuck system. The machine has rotational drive and milling spindle to enable orbital milling capability and orbital scroll milling.
Method
The machine is mounted using the eight jaw chucking system with four off having an adjusting feature built in to allow fast easy levelling. Four off additional jaws are used to provide rigidity and the machine has a hydraulic rotary distributor to enable correct hose orientation at all times. The machine is mounted to the tower fabrication locked in place, levelled and then machining can commence. High spots can be removed locally without the need to complete a revolution or alter cutting speeds.
