Modular 5-axis machining centers for automotive mass production
The G-Series modular machining centers were developed to meet the demands of modern automotive production. The machine design combines highly dynamic 5-axis machining, maximum process stability, and flexible automation solutions for cost-effective series production with short cycle times.
Whether as a standalone machine or a fully automated production line, the G Series enables scalable production with high repeatability and reduced setup time.
Reliable 5-axis task for complex parts
The G Series is based on a machine concept developed specifically for mass production. Three linear axes and two rotary axes enable high-precision 5-side machining of complex part geometries while delivering high dynamics and rigidity.

FAQ - Frequently Asked Questions About GROB's G Series
Modular machining centers consist of machine and automation components that can be flexibly combined. This allows manufacturing solutions to be precisely tailored to individual production requirements and production volumes.
The G Series was developed specifically for the automotive industry and is particularly well-suited for powertrain and chassis components in mass production.
The machining centers are designed specifically for aluminum alloys, but depending on the configuration and process requirements, they can also perform other tasks on other stocks.
The horizontal motorized spindle improves chip removal and reduces thermal stress in the machining area. This increases process stability during long production cycles.
Yes. The machines can be integrated into fully automated production lines featuring gantry systems, robots, and workpiece handling systems.
Reduced non-machining time, high dynamic performance, fewer voltage changes, and automated processes lower unit costs while maintaining high production quality.
