500 DUO / 600 DUO

With the large spindle spacing of 810 mm or 720 mm, the
SPECHT® DUO series for machining large components is
completed. Large cylinder blocks (6 and 8 cylinder), cylinder
heads, cases and other large components are as much a part
of the range of applications as multiple clamping of steering
knuckles and similar workpieces. The option of linear motors
and strong spindles with HSK-A100 ensure high productivity
in flexible systems. Technology precision machining (honing
and fine boring) is available for the SPECHT® 500/600 DUO.
Machines equipped with draw bar spindles are not only
suitable for honing, but also for wear compensation, e.g. for
precision boring, face turning on the machining center and
thrust bearing processing.

Advantages of the SPECHT® DUO machines

  • Large distances between the spindles for machining large
    workpieces                                                                                          -810 mm on the SPECHT® 600 DUO
  • HSK-A63 motor spindle with speeds up to 18 000 rpm
  • HSK-A100 motor spindle with up to 378 Nm / 38 kW
  • Fast tool magazine (L chain + 2 discs) with high capacity
    (112 usable tool spaces)
  • Chain magazine allows fitting on ground level without
    a podest
  • Smallest surface area requirement due to compact design
  • Portal, frontal or manual loading possible
  • Worldwide unique „dynamic axis compensation“ (X/Y/Z)
    brings the precision of the single-spindle machine to the
    DUO machine
  • Wet processing to meet technological requirements possible
    just as 2-channel minimal quantity lubrication with highly
    precise dosing for environmentally friendly production
  • Steep walls in the machine bed and chip tray ensure very
    good chip discharge in MQL machining
  • Workpiece clamping with zero point clamping system or
    adapter plates – reduction of clamping elements, permanently
    high accuracy and fast changeover
