Doosan introduces its FM 200/5AX Linear five-axis machining center, designed for simultaneous five-axis contouring for a range of complex parts including medical devices, automotive turbochargers and other precision parts. Built on a rigid bridge-type base and composed of stable mineral composite material, the machine’s castings absorb vibration at ten times the rate of iron castings, according to the company, and are more thermally stable for effective part surface finishes and increased tool life.
Offering rapid traverse rates of 1,968.5 ipm and cutting feed rates of 787 ipm, the machining center’s X-, Y- and Z-axis travels measure 7.9" × 13.4" × 11.8". All three axes are driven by high-precision linear motors, providing high acceleration and deceleration feed rates with little to no backlash. The fourth- and fifth-axis rotary tables are equipped with direct-drive motors to deliver matching levels of performance. A 7.9" diameter platten can handle 33.1 lbs.
The 19-hp spindle features an HSK E40 taper and achieves speeds of 45,000 rpm for minimized vibration and maximized stability. For added productivity, the machine uses a direct-drive, servo-driven, 24-tool automatic toolchanger capable of holding tools as large as 2" in diameter and 7.1" long, weighing as much as 2.2 lbs.
The machining center uses a Heidenhain TNC control to accommodate complex part processing. The control includes an ergonomic swivel pendant and a 19" screen.
