5-axis CNC machining center G9 series

verticalHSK A-63for the automobile industry

Concept
Discover the machining capabilities of the G900 series for mega- and giga-castings. The G920F5 provides 5-axis machining for complex contours; the G920F4 is available for high-performance 4-axis operations. Modular configuration, multiple spindle layouts and robust thermal management support accurate, repeatable production of large automotive and structural components.

G920F4 / G920F5 overview
G920F4: optimized for precise 4-axis machining with two horizontally or vertically aligned spindles and a table for parts up to 2,900 mm long.
G920F5: adds full 5-axis capability for complex geometries while retaining the same modular platform and spindle layout options.

Key features

• Linear X, Y, Z axes drive the machining spindle for high positioning accuracy
• Optimized axis dynamics and rigidity for short chip-to-chip times and stable cutting
• 4-axis (G920F4) and 5-axis (G920F5) configurations available
• Spindle options: two horizontally or vertically arranged spindles; single-spindle variant available
• Thermal management and temperature concept designed for machining accuracy
• Modular design for flexible production and simplified retooling
• Max. part size example: Ø 2,000 mm / L 2,900 mm

Automation

• Robot automation: front loading or top loading
• Custom automation solutions to match production requirements
• Loading into the work area via double gripper for short cycle times
• Integration of ancillary processes: deburring, washing, marking
• Standardized components enable quick installation and reduced commissioning time

Linear gantry (automation option)

• Fully automated direct top loading for high throughput
• Simultaneous horizontal and vertical movement increases handling efficiency
• Top loading leaves machine ground-level access unobstructed
• Optional telescopic gantry available for low building heights

Typical machining operations

• Battery trays and structural battery components
• Mega- and giga-castings for automotive applications
• Large body components and structural parts
