2007 ZIMMERMANN FZ375 VERTICAL MACHINING CENTERS

Technical Description

The 2007 Zimmermann FZ375 is a 5-axis large-format gantry portal machining center manufactured by F. Zimmermann GmbH of Denkendorf, Germany. The FZ375 is a member of Zimmermann's FZ37 portal milling machine family, representing a specific configuration of the modular FZ37 platform. Like all machines in the FZ37 series, the FZ375 is built around a traveling-gantry architecture suited to machining large aerospace structural parts, tooling, and composite components. The portal moves along floor-level X-axis slideways over a stationary worktable, with the motorized 2-axis milling head providing full 5-axis simultaneous contouring capability. The machine features high-frequency spindle technology for productive cutting of aluminum, titanium, composites, and steel, with the Siemens 840D CNC control providing 5-axis interpolation, look-ahead, and high-speed cutting cycles. All axis movements are carried on preloaded recirculating roller guideways with ballscrew drives. The FZ37 family supports X-axis configurations from 3,000 to 40,000 mm, Y-axis from 2,500 to 6,000 mm, and Z-axis from 1,250 to 3,000 mm, with the specific travel envelope of the FZ375 determined by its configured installation. Spindle power is in the range of 45 to 74 kW (approximately 60 to 99 HP) depending on the milling head fitted, with spindle speeds to 24,000 RPM. Due to the machine's modular construction, overall footprint and weight are installation-specific.
