Machining Facility
Denel Aerostructures Machining Facility consists of a main NC machining department where machining of all major parts takes place, as well as two dedicated machining cells (one for main rotor head parts and the other for pylon parts). A jig boring department and conventional machining department complete the facility.

The Machining Facilitys staff complement comprises 90 people. Personnel are trained and experienced in operating the machines. Intensive additional training is provided during commissioning of new machines.

Parts machined in the facility range from the extremely complex such as main rotor hubs, swash-plates, pylon sole plates and rear fuselage frames, to simple brackets. Denel Aerostructures also operates a number of high speed 5-axis NC machines.
