GFM FKP 60 HORIZONTAL MACHINING CENTER

The 1984 GFM FKP 60 is a high-capacity horizontal machining center designed for precision milling of large crankshafts and similar long workpieces. It accommodates a maximum workpiece length of approximately 19.69 feet (6000 mm) with a maximum working length of 19.03 feet (5800 mm), and a center height of 6.89 feet (2100 mm). The machine features significant longitudinal carriage travel of up to 19.68 feet and a clamping head stroke that matches the maximum working length. It operates with a portal stroke (X-axis) and a milling carriage stroke (Y-axis) each at 2.99 feet, supporting complex multi-axis machining tasks. The rapid traverse speeds are notably high: the longitudinal carriage moves up to 13,086.6 in/min (332.2 m/min), while both the portal and milling carriage achieve rapid speeds of 9,000.8 in/min (228.6 m/min), enabling rapid setup and efficient material removal rates. Working feed rates for portal and milling carriage range from 0 to 78.74 in/min (0–2000 mm/min), providing fine control during milling operations. The machine’s cutting head has a large outer diameter of 5.51 feet (1680 mm) with a cutting head diameter of 3.44 feet (1048 mm), running at multiple speeds from 27.6 to 36.2 RPM, corresponding to cutting speeds between 311.7 and 410.1 ft/min. The moving steady rest allows clamping diameters from 8.66 to 19.69 inches, ensuring stable machining of extended crankshafts or similar cylindrical parts. This robust configuration, combined with its precise travel and feed capabilities, makes the GFM FKP 60 suited for heavy-duty crankshaft milling with substantial size and power capacity.
