The processing of aircraft aluminium structural parts begins with heavy forged sheets, of which a ribbed structure with 10% of the original mass will remain.
The processing of aircraft aluminium structural parts begins with heavy forged sheets, of which a ribbed structure with 10% of the original mass will remain.
The production lines of the primary suppliers of these parts use specialised 5-axis Machining Centres of very high productivity: the amount of milled chips is between 5 and 10 LT/min., and they use Electric Spindles with a power of up to 130Kw and cutter rotation speed between 20,000 and 30,000 rpm. The key point of quality that determines the productivity of the machine is the excellent dynamic and structural rigidity that must be achieved between the tool and the “cut” chip.
The SATURN head directs the Electric Spindle with two axes that are superimposed and inclined to each other at 22.5 degrees, which limit the operating angle of the ES to just +- 45 degrees (#), but generate exceptional structural and dynamic rigidity that is superior to any other head configuration so far.
