Highlights
GMC series by DMG MORI

With experience from more than 4.500 CNC multi-spindle automatic turning machines installed worldwide

  • GMC 20 with central drive for all the six main spindles, up to 31 controlled NC axes and spindle stop and positioning as option
  • GMC 20 ISM with separate integrated spindle motor with C-axis for each main spindle, up to 56 controlled NC axes, machining highly complex workpieces
  • Bar diameter extension up to Ø1 in. as option


Machine concept with maximum stability for high-precision workpieces

  • Maximum rigidity as a result of the stable portal structure of the machine to minimize distortion during machining
  • Optimum damping characteristics as a result of the machine bed, main and front-working tool spindle construction and the upper brace
  • Maximum thermal stability as a result of axially symmetrical machine structure


A solution for every workpiece

  • Radial tooling for the productive manufacture of complex workpieces with the possibility to mount double tool carrier, milling unit, polygon turning unit and multiple turret disc
  • Front-working tools for fast cycle time with overlapped front working operations
  • Pick-up spindle for back-working operation of complex workpieces
GMC series by DMG MORI

Top performance for high-batch series production

  • 1 g acceleration of the linear axes for great dynamics and reduced per-piece production times
  • Movable and programmable (opt.) center block for maximum stability during front machining
  • Up to 65% quicker and cost-effective retooling of the machine as a result of CNC-controlled axes
  • Quick change system for preset tools on the cross slides with < 0.1 µin repeatability
