Efficient Manufacturing of Frame Structure and Chassis Components with the F Series
GROB’s F Series was developed specifically for the cost-effective task of machining frame structure and chassis components, as well as battery housings. The machine platform combines high dynamics with reliable 5-axis technology, thereby providing optimal conditions for automated series production processes in the automotive industry.
Whether as a single machine or as part of a complete production line, the F Series—with its single- and two-spindle machining centers—enables short cycle times, stable processes, and maximum flexibility when performing large-volume structural component tasks.
Designed for highly dynamic production processes
With its various machine configurations, the F Series offers a specialized platform for performing complex automotive tasks. The machines are suitable for dry machining, MMS processes, and conventional wet machining, and meet the requirements of modern production lines in body and chassis manufacturing.
The machine design was systematically optimized for high process stability, optimal chip removal, and minimal non-machining time.
- Free chip fall and efficient heat dissipation
Steep machine bed slants and the optimized axis arrangement ensure a clean work area and stable machining conditions. - High machining accuracy
The rigid machine structure and the horizontal motorized spindle in a cross-slide design enable reproducible results in series production. - High manufacturing
flexibility The modular machine design reduces setup times and allows for flexible adaptation to different workpiece geometries. - Optimized for MMS task
The work area design and the combination of the A and B axes create ideal conditions for minimum quantity lubrication. - Short chip-to-chip times
Dynamically tuned axis drives reduce non-machining times and increase productivity. - 5- to 6-side task in a clamping setup
Three linear axes and two rotary axes enable the complete machining of complex structural components.

FAQ - Frequently Asked Questions About GROB's F Series
Machining centers for frame structure parts are specially designed CNC machines for the high-precision machining of large-volume automotive components such as chassis parts, structural components, or battery housings. They enable cost-effective mass production with a high degree of process reliability.
5-axis machining allows multiple sides of a workpiece to be completed in a single clamping operation. This reduces setup changes, machining times, and tolerance deviations. At the same time, process stability increases.
Large aluminum or structural components generate large amounts of chips. Efficient chip removal prevents heat buildup, reduces machine downtime, and improves process reliability during mass production.
Yes. The F Series is designed for use in automated production lines and can be integrated with robots, linear gantries, and workpiece handling systems.
The machines are particularly well-suited for aluminum structural components, chassis components, and battery housings. Depending on the machining process, other lightweight materials can also be used for tasks.
MMS stands for minimum quantity lubrication. This method uses only a very small amount of lubricant. It reduces fluid consumption, simplifies chip disposal, and improves manufacturing efficiency.
Single-spindle machining centers offer high flexibility when processing a variety of parts. Two-spindle machining centers increase productivity and enable shorter cycle times in highly automated production processes.
