Large-part machining

Bertsche Engineering (Buffalo Grove, Ill.) has developed the P5 bridge mill, designed for one-off machining of profile beams and other large parts in aerospace production environments. The system provides x/y/z travels of 300 inches by 60 inches by 30 inches (762 cm by 152.4 cm by 76.2 cm) and speeds up to 2,000 ipm

Bertsche Engineering (Buffalo Grove, Ill.) has developed the P5 bridge mill, designed for one-off machining of profile beams and other large parts in aerospace production environments. The system provides x/y/z travels of 300 inches by 60 inches by 30 inches (762 cm by 152.4 cm by 76.2 cm) and speeds up to 2,000 ipm (50.8 m/min). The mill handles profile beams made from composite layups, sandwiched composite/aluminum/titanium materials, and extruded aluminum or monolithic structures made from aluminum plate. Table configurations for composite, aluminum extrusion, bar and plate work are available. Its B/C Direct Drive Fork Type Head and 20,000-rpm, 43-kW spindle reportedly provide the acceleration and feed rates required for long-part machining. The Smart Work-Holding Fixturing system features automatic setup for more than 50 part configurations for C, H and J beam profiles, including profiles with varying cross-sectional thickness. The machine’s workholding features permit mill, drill, rout, saw cut and inspection operations in a single part setup. The manufacturer says this mill is currently in use on the Boeing 787 and 777 programs.
