Press and representatives from all over the world gathered at Studer AG’s headquarters in Steffisburg, Switzerland, for the company’s annual meeting, which included a press conference and a guided facility tour.

Fritz Studer AG, a member of the United Grinding Group, held its annual meeting on Feb. 9, 2024, at its headquarters in Steffisburg, Switzerland. This year’s event was titled the “Music Motion Meeting” with the theme of “Sound of Studer.” Approximately 65 journalists from over 20 countries attended the event, which began with presentations from the company’s board of directors. After the conference, attendees were given a guided tour of Studer’s headquarters, which featured demonstrations and explanations of entry-level grinding machines and automation solutions.

Market Outlook

The press conference featured a rundown of 2023 sales figures. CEO Jens Bleher says the year was “extremely successful,” with sales growth in two of its largest markets: the U.S. and China. Asia was, as it has been in previous years, the largest region for sales alongside Central Europe and North America.

Although the development of incoming orders was weaker in individual markets, such as Germany, China, and some Asian countries, other parts of the world saw positive results. “We achieved good results in many countries and even posted a new record order intake in some,” says Studer CSO Sandro Bottazzo. The customer care segment of the business set a sales record for the second consecutive year. Customer care includes areas from maintenance and service to spare parts and overhauls.

Measured by customer segments, the aerospace industry once again generated the largest increase in new orders. The industry has now overtaken the declining automotive and supplier industry. The tool segment remained below expectations, while the largest individual segment is precision engineering, which is dominated by contract manufacturers. “I am very pleased that our grinding machines are so highly trusted by small and medium-sized enterprises, and that this segment remains strategically important for us,” says Bottazzo. Additionally, Studer is seeing an increasing demand for precision cylindrical grinding machines in the semiconductor industry.

Automation and Entry-Level Solutions

Globally, Studer participated in about 30 trade shows and open houses. At EMO 2023, the company unveiled its new InsertLoad loading system, which it also showed during the facility tour. The new universal loading system enables standardized automation for loading and unloading Studer’s S33 and S31 grinding machines. InsertLoad can be used for center distances of up to 39.4 inches. The workpieces can be up to 3.94 inches long and weigh 3.3 lbs in alternating mode or 11 lbs in a single mode. The design and ease of use with the digital setup wizard allow users to configure this for centers and chucks – no programming knowledge is required. Additionally, InsertLoad can handle workpieces that are stored either vertically or horizontally. Loading and unloading is handled by a FANUC robot, which moves independently on a linear axis between the loader and the machine’s work area. This system can reduce the time without human operator intervention, which typically is between thirty and sixty minutes.

The machines in the entry-level segment include the Favorit, FavoritCNC, and S100. The Favorit is a cylindrical grinding machine with a 24-inch touch screen, and the company says it can grind both short and long workpieces that weigh up to 330 lbs. The FavoritCNC can be adapted to a variety of grinding tasks with different options such as a measuring system, balancing system, contact detection, and longitudinal positioning. With a distance between centers of 25.6 inches or 39.4 inches, it is suitable for a variety of uses.

The S100 handles a wide range of internal, face, and external grinding applications. Its specialty is the complete machining of workpieces with a length of up to 21.65 inches (including clamping devices) and a diameter of up to 16.5 inches. Thanks to the wheelhead with multiple grinding spindles, Studer says these features significantly reduce setup and resetting costs.

“We are continuously expanding our entry-level range for customers who appreciate Studer quality and utmost precision but do not need all the features from the premium segment,” Bottazzo says.

Adds Daniel Huber, CTO of Studer, “Compared to our high-end models, the number of tools and range of spindle power is limited, and many technical processes and interfaces standardized — this allows (the entry-level machines) to cover a wide range of grinding applications with excellent value for money.”

Fritz Studer Award

Studer concluded the conference portion of its event by presenting the 2023 Fritz Studer Award. Dr. Emil Sauter from the Institute of Manufacturing Technology and Machine Tools at ETH Zurich was the award winner, receiving a prize of 10,000 Swiss francs, or just under $11,400. His topic, “Detection and avoidance of thermal damage for high-performance metal grinding processes using hybrid machine learning models,” deals with the development of an innovative condition monitoring system for external cylindrical grinding with metal-bonded CBN tools that recognizes thermal damage and predicts the remaining useful life of grinding tools with relative accuracy. Process parameters such as structure-borne noise, spindle current, force characteristics and the use of time-frequency transformations generate features of a grinding process to detect different stages of thermal damage to the workpiece.

The award is aimed at graduates from European universities and technical colleges. Research focus for the award covers any of the following topics:

  • Innovative machine concepts or components for machine tools used in precision machining

  • Alternative materials in the machine tool industry 

  • Simulation models for the dynamic and thermal behavior of machine tools

  • Control and sensor concepts for machine tools

  • New or evolved manufacturing techniques, especially in precision finishing processes like grinding, hard turning, etc.

“The objectives of the research prize are, on the one hand, to boost innovation in the machine tool industry with feasible solutions, and on the other hand, to promote young technical and scientific talents,” says Dr. Frank Fiebelkorn, head of research and technology at Studer.

This year’s event concluded in the evening with a group dinner in Bern, which featured live music and entertainment.
