The FZU22 offers a working range from 71 to 98 in. in the X-axis; 118 to 138 in. in Y; and 49 in. in Z.

ZIMMERMANN MILLING SOLUTIONS will present a five-axis portal milling machine for lighter-weight machining for large structures at IMTS 2026, booth #339336.

With FZU22, Zimmermann is introducing a machine capable of machining various workpiece shapes, sizes, and materials. Aluminum, plastic, wood and other substrates can be processed, as well as finishing carbon fiber-reinforced and other composite materials.

The overhead gantry promotes precision manufacturing of models and molded parts. A standard machine includes a toolchanger for 24 tools and a CNC (Siemens or Heidenhain) for full motion control and tracking, while a specially developed five-axis milling head with a 15-kW spindle can mill complex contours and tight pockets in large molds.

Zimmermann FZU22 with CNC

A standard Zimmermann FZU22 machine includes a toolchanger for 24 tools and CNC for full motion control and tracking. A specially developed five-axis milling head with a 15-kW spindle produces complex contours and tight pockets in large molds.

The FZU22 offers a substantial working range, from 71 to 98 in. in the X-axis; 118 to 138 in. in the Y-axis; and 49 in. in the Z-axis. A feed rate of 2,756 ipm in the X- and Y-axes is standard while the acceleration on the machine is max. 118 in/sec2 to 197 in/sec2.

With a compact footprint of 11 x 15 ft, the machine fits in any small space available in a shop with minimal foundation requirements. ISO 230-2 accuracy is certified.

A choice of milling heads is offered on the machine to suit a variety of applications.

Optional equipment offerings include a touch probe, tool measuring system, work area cover, tool changer, chip conveyor, mist/dust extraction system, minimum quantity lubrication and a vacuum system.

The FZU22 machine to be displayed at IMTS will features an ultrasonic system for cutting aerospace insulation.
