Portal/Overhead Five-Axis Gantry Milling Solutions



The Droop+Rein FOGS NEO high-speed machining center with its flexible and fast C-axis is suitable for multi-functional complete processing of large workpieces

HD characteristics: "With enhanced machine dynamics, the new Droop+Rein FOGS HD (Heavy Duty) can finish items around 20-30% faster and more economically than a comparable portal-type milling machine," said a company spokesperson.

Starrag has announced its Droop+Rein vertical milling centers (VMCs) with the launch of three new machines - led by the Droop+Rein FOGS HD which offers heavy-duty cutting - and the evolutionary NEO update of four existing series machines.

"The result is that its Droop+Rein portal, gantry and overhead gantry milling portfolio offers from a single source a complete spectrum of large vertical 5-axis milling solutions, from high-speed to heavy-duty cutting, to users across Starrag's focused industry sectors of aerospace, energy, transportation and industrial," said a company spokesperson.

The new developments and updates involved all existing machine designs and now complete the Droop+Rein product range of large VMCs:

  • Overhead gantry design - the new Droop+Rein FOGS HD and updated FOGS NEO/N40 machines
  • Floor-guided gantry design - the Droop+Rein GS and GFS NEO/N40 models, complementing the existing up to 201 HP G and GF series
  • Portal design - the updated Droop+Rein TS and TFS NEO/N40 machines, adding to the existing T and TF models that feature 201 HP spindle power and 8,850 ft-lbs. machining capability.

These Droop+Rein revelations are headed by the new FOGS HD machine which, said Starrag, takes heavy-duty cutting to the next level by combining the dynamism and precision of overhead gantry machining with the output of rigid portal/gantry milling.

"Following Starrag's philosophy of modular design, this new machine with hydrostatic guideways can be supplied with a choice of control systems, table configurations, milling heads, tool changing system and spindles - rated up to 134 HP/5,531 ft-lbs. - to satisfy even the most demanding tasks asked of its expansive X-, Y- and Z-axis travels of 1,220 in., 236 in. and 98.4 in., respectively. Feedrates are 1,575 IPM in X and Y, and 787 IPM in Z," added the spokesperson.

Droop+Rein's evolutionary update of its milling technologies is exemplified by the machines with the NEO designation, and it includes a new rack and pinion drive system for the ram (Z-axis) and an integrated C-axis design of +/- 400° using a torque drive.

The enhancements to the NEO machines' main milling drive - which utilizes the multi-functionality of a 53.6 HP main spindle drive and head change, and are designated as N40 models - include a new main drive motor and two-stage gearbox that can now be extended to 80.5 HP and 1,327 ft-lbs. in S6 mode.

These design features will be implemented into the FOGS and the updated TS/TFS machining centers. The integration of these attributes into the new GS/GFS floor-guided gantry machines completes the comprehensive range of machine choices now available.

A wide choice of milling heads (over 300 different styles/ratings) are available, allowing Droop+Rein technology and application experts to configure the machines to meet current and future applications.

All machines feature Starrag's in-house developed Integrated Production System for real-time feedback of machine status and performance, in line with Industry 4.0 principle.
