125 PARTS TO ONE
A Makino machining center produced a complex component, similar to the one shown, forBoeing as a single, complete part, replacing the previous manufacture and assembly of 125 parts. Manufacturing lead time has improved by 30%. Using an off-the-shelf 50-taper spindle running at speeds between 8,000 and 15,000 rpm, the machining center produces a precision feedrate of 240 inches (6,090 mm) per minute, versus 60 ipm (1,524 mm/min) for the old manufacturing method. Because high-speed machining removes the heat in chips, the floor and walls are machined to 0.020" (0.51 mm) thickness, maintaining critical tolerances without distortion or oil-canning. The part’s mold line surface demonstrates the ability to accurately produce changes in direction andtilt.
