Automation and high precision, par for the course for Prisme Méca With its many years of experience, Prisme Méca sets the standard when it comes to machining complex, highprecision parts. Founded on know-how and an industrial vision focused on peak performance in production, the company headquartered in Le Grand-Lemps, a short distance from Grenoble, has experienced double-digit growth for over 25 years. With support from EROWA, the management board is introducing a flexible and competitive production system that is making it possible to achieve further performance gains.
The company, established in 1998, was acquired in late 2021 by SAS Triologic and has since belonged to the corporate Group of the same name, along with the engineering office Mécanic 3D. With these three complementary companies, the management board has successfully set a course for external development aimed at continued growth and providing customers with an even more diverse and extensive range of products. Automation as the cornerstone of a sustainable strategy With more than seventy employees and fifty machines at the three locations, the Group is able to meet even the most demanding requirements of its customers - who are now diversified across numerous industries, such as medical, aviation and aerospace, military technology, and many more. „In order to support our customers‘ growth, we decided to invest in human and machine resources. This fits in perfectly with our strategy of fostering industrial expertise in our region while also growing our company, to offer our customers an increasingly competitive Industry 4.0 service,“ explains Jérôme Guignard, Head of Engineering at Prisme Méca and Managing Director of Triologic.

project. Given the requirements and the expected volumes, the investment in a new robot-controlled production line was the logical choice to provide the customer with reliable and longlasting services. Prisme Méca therefore invested in four 5-axis Mazak CV5-500 machines and one rail-guided ERD150L robot to serve all the machines. The robot continuously supplies all the machines from four magazines with up to 200 storage locations.

The management of Prisme Méca opted for the solutions from EROWA particularly on account of this industrial vision, which is founded on continuous improvement and machine fleet automation. For a number of years, EROWA expert Dominique Ramousse has supported the company in its development and brought his analytical experience on board to propose the best tools for improving general productivity and increase the responsiveness and flexibility of the production facility. In the milling area, which includes numerous 5-axis machines from DMG, the ERC 80 Easy and Multi robots are already in use. With the associated tooling systems, the production site has continuously developed and improved its production capacities for milling complex parts. This is confirmed by Dominique Ramousse: „Our robots adapt perfectly to any type of machine they are linked to. At Prisme Méca, the various 5-axis DMU 40 eVo and DMU 60 eVo machines were the starting point for our collaboration, and the selection of the associated robots was the subject of a special study aimed at attaining the optimal production organization.“ This decision turned out to be the right one for the management of the company based in Le GrandLemps. And when it came time for the latest investment, they of course once again turned to EROWA. Improved reliability and level of service When one of their biggest customers asked them to develop complex milled parts in the field of robotics, Jérôme Guignard and Michel Rubio quickly recognized the challenges of the
The new island with an investment value of EUR 1.3 million has been operating now for several weeks. Three new positions were also filled for the new production line. „Before the ERD150L was installed, our production facility was already operating in three shifts around the clock. But since the robot was put into operation, we have been able to optimize our service level while also rebalancing our staffing resources. Now, the previous night shift provides daytime support. The machines are now running autonomously at night and on the weekends,“ notes Guignard enthusiastically. The system was complemented by the EROWA JMS 4.0 ProductionLine software, which gives users an efficient, easyto-use interface. The head of the Mazak division, Rémi Di Benedetto, who was hired to install this new line, agrees:

„The machines are mostly programmed manually during the day, and at the end of the work day, the last operator present sets the four machines for automatic mode, so that they run all night and on the weekend. This way, we can produce up to 8,000 parts per week.“ With this new system, Prisme Méca continues to grow, making production more reliable and guaranteeing customers a high level of responsiveness and competitive prices. With production excellence as a driving force and shared values, the partnership with the automation specialist is an undeniable advantage that will be further enhanced by the upcoming installation of more machines coupled with EROWA robots.
