Droop+Rein G/GF

6-axis machining center

How can large, heavy-duty and bulky workpieces be processed without adversely affecting the weight and size of the machining result? The Droop+Rein G/GF series has been specifically developed to tackle this difficult task. The gantry machines reliably prevent dynamic losses through the table and workpiece. The G/GF series has many technical highlights to meet the requirements of complex machining tasks, such as the hydrostatic guide in all linear axes or the thermo-symmetrical design of the spool milling unit with an integrated C-axis. Milling heads can be changed automatically via a head change interface.

Droop+Rein has developed over 300 different milling heads for a variety of applications – such as machining large diesel engines. The option to set up in a second working area during the machining time allows increased productivity.

Technological advantages:

  • Optimum development of potential in the machining of large and heavy workpieces
  • Floor plate for cubic workpieces
  • Rotary table for rotationally symmetrical workpieces
  • Comprehensive Starrag diagnostics system
  • Industrie 4.0 proved via Starrag IPS
  • High energy efficiency
  • Comprehensive peripheral devices
  • Large number of automatically interchangeable milling units
  • Integrated rotary table (milling/turning)
