GROB
What is GROB?
GROB is a German manufacturer of machine tools and production systems, developing and producing machining, automation, and assembly solutions for the metalworking industry. The company was founded in 1926 in Munich, and its headquarters are located in Mindelheim, Bavaria. GROB is a family-owned business serving customers worldwide through multiple production facilities and service units.
GROB is especially known for its horizontal 4- and 5-axis machining centers, designed for demanding CNC machining with high cutting forces and reliable processes. These machines are widely used in machine shops manufacturing precise parts with tight tolerances.
GROB and the Development of Machine Tools
GROB has been involved in the development of machine tools for almost a hundred years. The company's production initially focused on special machines and transfer lines and has since expanded to modular machining centers and complete production systems. GROB's machine development emphasizes rigid construction, thermal stability, and machining accuracy, which are key factors for production quality in machine shops.
The horizontal spindle concept is one of GROB's core solutions. It enables efficient chip removal, a consistent cutting process, and high surface quality, especially in 5-axis machining.
GROB Machining Centers in the Metalworking Industry
GROB machining centers are used in CNC machining for milling, drilling, and complex multi-axis operations. The machines are particularly well-suited for machining aluminum, cast iron, and steel, but are also used for working with more demanding materials in machine shops and industrial production environments.
From a machinist's perspective, GROB machines stand out for their excellent accessibility, clear design, and compatibility with various CAM software and CNC control systems. This supports efficient production and consistent quality in both batch and piece manufacturing.
Automation and Production Systems at GROB
In addition to machine tools, GROB supplies the metalworking industry with automation and production systems such as robotic cells, pallet changing systems, and flexible manufacturing lines. These solutions aim to improve machine utilization rates, reduce manual handling, and standardize production processes.
GROB's automation solutions are especially beneficial in industries where production volumes are high and process repeatability is critical. These systems are integrated into modern CNC machining and Industry 4.0 environments.
GROB and E-Mobility Production Technology
In recent years, GROB has expanded its activities to the assembly technology of electric motors, battery modules, and batteries. These solutions do not replace traditional machining but complement the company's offerings, especially for the automotive industry and other metalworking supply chains.
E-mobility systems combine automation, assembly, and precision machining, leveraging GROB's extensive expertise in designing production systems.
GROB's International Operations
GROB has production facilities in Europe, Asia, and North and South America. Although the company’s roots are in Germany, its machines and systems are used in machine shops worldwide. An international service network supports installation, maintenance, and lifecycle care for the machines.
For machine shops, this means access to spare parts, technical support, and training over the long term.
Summary
GROB is an established German machine tool manufacturer that develops horizontal 4- and 5-axis machining centers as well as automation and production systems for the metalworking industry. The company's solutions are designed for demanding CNC machining where precision, process reliability, and production efficiency are essential. GROB machines are widely used in machine shops around the world, especially for mass production and industrial manufacturing systems.
