Following the acquisition, DMG meccanica became part of the GROB Group without any changes being made to its corporate structure. To complete its integration and optimize its structure, DMG meccanica has undergone the final step of the acquisition and been renamed GROB Italy Srl. The Management Board remains unchanged and continues to consist of the DMG meccanica company founders Mr. Marco Debillo and Mr. Mauro Marzolla.

Sales and service branch GROB Italia (Turin), headed by Managing Director Mr. Antonio Goia, will be integrated into GROB Italy Srl during the course of 2018.
As such, GROB Italy Srl will comprise two corporate areas in the long term: DMG meccanica will be renamed as GROB Italy.

This structured initiative points the GROB Group the right strategic direction and also puts us in the ideal position to master new challenges in the future and meet the needs of our customers.


Windings for distribution and power transformers

electrical windings production

Italian Windings Group was created in 2013 by the joint venture of Elettromeccanica Mercanti and Due Esse, two Italian companies with a combined experience of nearly 100 years in the field of electrical windings production. The objective is becoming the one contact on a national and international level for the supply of windings for Distribution and Power Transformers dry type, oil-immersed and cast resin with power ranging from about 10 kVA to 100 MVA. The strategic decision of combining efforts to offer outstanding know-how, constant innovation and passion is driven by today’s market trend for buyers to address a restricted number of providers who are able to secure efficiency and reliability, in terms of raw materials, manufacturing and concerning procedures and ethics. By centralizing purchasing, marketing expenses and trade relations, Italian Windings promises its customers high quality and competitive prices. Due Esse constructs customized electrical windings for dry type, oil-immersed and cast resin power transformers for Clients in the energy, marine, rail and industrial sectors. In 2003, Due Esse obtained the UNI EN ISO 9001 certification and is subject to periodic scrutiny of the business management system by Det Norske Veritas. Elettromeccanica Mercanti began its’ activity in 1972. The company specializes in the production of primary and secondary windings for distribution transformers in oil up to a power of 2.500 kVA.

Safety and efficiency in manufacturing automation


Cosberg designs and manufactures plants to automate the mounting systems for all types of electric motors, such as for instance brushless, AC, DC and stepper, intended for several sectors, among which stands out the Automotive. An ambit where, even more than in others, efficiency and safety are essential issues.
For this reason, Cosberg can integrate all available technologies to carry out tests, measurements and controls into the plants, designed and manufactured by the Italian company: dimensional vision controls, component presence, positioning, automated contacting and related electric and tin welding, controlled dosing for the sealing bicomponent, tightness or insulation tests, checks of the noise level, electric tests and so on.
automation Control and traceability are nowadays irremissible conditions because they allow filing the “story” of each single part and, if necessary, tracing back all underwent machining operations. Therefore, on one hand Cosberg machines assure – and can prove – that each single product has been assembled in full compliance with all specifications provided for by the manufacturer; on the other hand, they must provide each workpiece with its own “package” of information, transmitting all detected data to manufacturers and thus allowing them to monitor, to prevent, to improve and to process statistics. Customers can define what kinds of controls to perform for each production and decide that each single product is labelled and monitored for the entire lifecycle, managing to store all information types: what processes it underwent (and when), on  what car it was mounted, what parameters have characterized its production and the values obtained from trials and eventual testing.
Flexibility is another very important aspect for the plants devised for this sector. In fact, for both high-end and “standard” products, there are always countless variables that give birth to endless models and variants. This has led Cosberg, in time, to study solutions offering high reconfigurability levels and drastically reduced set-up times, to meet the ever-rising trend of customizing all aspects of cars and motorbikes. Concerning this, the concept of Lean Production plays a fundamental role, as aimed at the waste reduction and focused on quality, pursuing perfection through constant improvements. Workflows are precisely engineered according to this vision, simplifying the entire manufacturing cycle and eliminating the activities that do not generate added-value, in order to make our systems more and more efficient and flexible.
automationCosberg always accepts the challenge for both aspects, traceability and flexibility, because Cosberg must work in synergy at mechanics, electronics and software to satisfy Customers’ expectations. A factor shared by both ambits is precisely the need of controlling and objectifying each operation, in order to eliminate human errors, to avoid wastes of time and resources and to supply “measurable” quality products.
Cosberg can manage all available market technologies that allow reaching these results, like for instance vision and measuring systems, linear and pressure transducers, system management software. Unavoidably, the latter must be faster and faster in filing and processing and, meanwhile, increasingly reliable and safe, as well as – not secondary characteristic – of immediate interpretation and use.
All that allows Cosberg to provide effective solutions to the scenarios that are emerging on the market – where the demand for smaller and customized batches is spreading – and in the advanced manufacturing industry, where production plants are consequently becoming increasingly adaptive, self-configurable and integrated into the manufacturing chain. In other words, Cosberg can state that its plants have already undertaken that evolutionary course that will lead, unavoidably, to that model of Factory that – rightly – Cosberg can define Intelligent.

Manufacturing technology for electro mobility

Manufacturing technology

At the end of January 2017, GROB acquired 100 percent shares in DMG meccanica, substantially reinforcing the competences and developments in electro mobility, which it has been developing for several years. The technologies of DMG meccanica and the new processes developed by GROB will now enable GROB to provide all the vital manufacturing processes and procedures in electric drives for the automotive industry and its suppliers worldwide, and also to supply them for series production in the near future. DMG meccanica has many years of specialization and experience in machinery and plant manufacture for the production of stators for electric motors, alternators andgenerators. The technological know-how is based on the tried-and-tested winding process of inserting technology and needle winding.
Most of the machinery and plant of DMG meccanica is used directly in the automotive industry. GROB develops and tests new processes, developed specially for the series production of stators for electric motors in electric vehicles, in its own development department. The future cooperation is therefore a win-win situation for both companies. GROB has secured further know-how in the field of electro mobility and DMG meccanica has found in GROB a strong, globally- oriented partner for series production. Further investments to expand these technologies in the field of electro mobility are planned at both sites in Turin and Mindelheim.

Closing ceremony- Grob and Dmg meccanica management.

Mauro Marzolla and the father of Marco Debilio founded DMG meccanica in 1992 from a spin-off of one of the leading Italian providers of winding machines for electric motors. In 2016, their company with a workforce of forty employees achieved a total turnover of ten million Euro. Their customer portfolio includes many well-known electric motor manufacturers and suppliers to the automotive industry. DMG meccanica is particularly well-represented in the important e-mobility market of China. Owners Mauro Marzolla and Marco Debilio will stay with the company in future and will continue to be co-CEO´s of DMG meccanica. In addition, DMG meccanica will remain an independent company within the GROB-Group, and all jobs in Italy will of course be retained.

A leading machine tool manufacturer

GROB-WERKE is an internationally active family company based in the Bavarian-Swabian town of Mindelheim, with a product portfolio ranging from universal machining centers to highly complex manufacturing systems including automation, and from machining assembly units to fully-automated assembly lines. GROB is one of the few machine tool manufacturers that produces and supplies both machining and assembly equipment. Since the production of electric motors demands special assembly know-how, it was logical for GROB to seek a competent partner from the field of electric motor technology. Its takeover of DMG meccanica enables GROB to emphasize more than ever its claim in drive technology to be a leading and reliable partner for the automotive industry.
