We have a customer who is doing an "exact" replica of a 962 Porsche
Using a G50 / 01 gearbox the right way up, means flipping the crown wheel --(as its a mid engine job)-- so, decided to do a billet diff housing --
Firstly, we do some reverse engineering for critical dimensions to create a model for cad cam, this then provides machine tool language for the 4 axis machining centre which uses various cutters to remove all the unwanted metal .
Then we start with a chunck of 6061 ally 350mm (14") square that we whittle away at till we have about 50% swarf, leaving a roughed out housing.
Next, is stress relieving or aging -- this allows the metal to relax or creep giving stable dimensioning for the finish machining
and wait for the next installment as we go thru the stages till completion
