GROB’s present portfolio ranges from universal machining centers to highly complex manufacturing systems with own automation function through to manual assembly stations to fully automated assembly lines. It also sets up production plants for electric motors and assembly lines for battery and fuel cell technology. GROB is also taking a giant leap into the digital future, finds out P.K. Balasubbramaniian in an interview with Mr. Jochen Nahl, Member of the Board & CSO, GROB Group. Excerpts:
As a globally operating, family-owned company, we have been developing manufacturing systems and machine tools for more than 90 years. The success story of GROB-WERKE began way back in 1926 when the company was founded by Ernst Grob, who was producing folding boats, weaving machines and stationary combustion engines at that time. In 1952, Burkhart Grob, the son of the founder, assumed responsibility for the company almost completely destroyed during the war and was able to forge the link to the emerging automotive industry with high-quality and technologically-convincing production machines. In 1968, the Mindelheim plant was built and the company’s headquarters was relocated from Munich to Mindelheim due to expansion requirements and future growth vision. The Munich site was closed.
Besides the parent plant in Mindelheim, the plants in Bluffton (USA), São Paulo (Brazil), Dalian (People’s Republic of China) and Turin (Italy) are part of the production network of GROB Group. This production network is expanded through twelve sales and service branches in South Korea, China, India, Russia, Great Britain, Hungary, Mexico, Poland, Switzerland, the Netherlands and the USA to guarantee the best service quality.
Even after Dr. Burkhart Grob passed away in May 2016, the future of the family company has been strictly set out. Christian Grob takes the company into the third generation as the new Supervisory Board Chairman. Even at this early stage, the next generation is being prepared for future tasks.
GROB Management
By purchasing DMG meccanica in January 2017, GROB has acquired a strong partner in the field of electromobility. GROB now also acts as a developer of system concepts for electromobility, which is a future-facing step for expanding the existing product range of highly-efficient manufacturing and assembly plants. In January 2018, DMG meccanica was renamed GROB Italy S.r.l.
The GROB Group generates worldwide revenue of over 1.5 billion euros with a workforce of about 6,600 employees. Our portfolio ranges from universal machining centers to highly-complex manufacturing systems with own automation function through to manual assembly stations and to fully-automated assembly lines. Furthermore, production plants for electric motors and assembly lines for battery and fuel cell technology are part of our product range. GROB engineers are delivering solutions for the technology involved in plasma coating of cylinder bores at engine components, in cutting high-strength turbine housings and machining structural and chassis components. By developing GROB-NET4Industry, our proprietary industrial software for the digitalization and networking of production systems, GROB is taking a giant leap into the digital future.
Meanwhile GROB is in a transformation phase as a supplier in all aspects of mass production within electromobility.
The product range of GROB-WERKE GmbH & Co. KG can be divided into the following areas: System solutions and special-purpose machines: Machining centers or flexible manufacturing systems are designed specifically for the customer’s part. Offering so-called turn-key solutions, GROB provides the required planning, engineering, manufacturing and commissioning on site at customers’ facilities – everything from a single source. In most cases, these systems consist of modular machining centers and special-purpose machines that are interlinked with the latest automation solutions. Typical parts are for example cylinder heads, crankcases, transmission case and housings for auxiliary units of the engine.
Universal machining centers: The machining centers are mainly operated as stand-alone machines but are also available with automation solutions. They are typically used in the aerospace, automotive and medical industries, in tool and mold industries and in case of flexible contract manufacturers.
GROB’s futuristic products. The company’s system machines, universal machining centers & assembly lines are among the best in the world.

GROB Service portfolio for E-Mobility:
With machine variants G500F, G520F and G600F, the design engineers at GROB have developed a series with specific features such as large work areas and high dynamics. The name of this new development sets the tone. The “F” in the product designation stands for “frame”. Our G500F, G520F and G600F are designed specifically for machining lightweight components such as frame structure and chassis parts, and can produce battery trays as well. Positive features such as the axis arrangement combined with high machine dynamics and large work areas, made possible by the horizontal spindle position, speak for themselves. The enormous dynamic is down to the newly developed axis drives. In addition, the machines are designed for MQL, dry or wet machining and can be configured either as stand-alone solutions or linked to other machines as part of the automated line. The machining accuracy is optimally matched to the part requirements of the sector concerned. The customer can choose between two part loading methods: Either top loading via a GROB linear gantry or front loading by a GROB pallet changer, a part changer, a part pusher, a robot or manually by an operator.
Within GROB-NET4Industry, we have been developing applications and solutions for a networked production within the Grob Group for several years now – and we are also using the applications in our factory association to increase the efficiency. In addition, GROB gives substantial support to the initiative for standardized connectivity of the German Association of Machine Tool Factories (VDW). Industry 4.0 offers great opportunities for machine and plant engineering and thus creates the basis to run the machines and systems resource-friendly, flexibly and productively.
Using web technology, the GROB-NET4Industry Manufacturing Execution System creates cross-plant transparency throughout the entire production process. GROB-NET4Industry features various modular components that can be combined in a highly customizable manner, ensuring the ideal solution for each specific application case.
