Wind is Spain’s largest and fastest-growing source of electricity. Engranajes Juaristi is keeping pace with this growth, and gears for wind turbines now represent 15 percent of its annual shipments. These gears are characterized by their high-quality requirements, thus enabling them to run smoothly, quietly, and with great reliability in even the harshest conditions. Engranajes Juaristi uses two Gleason P600/800G Profile Grinding Machines to perform the critical hard finishing operations on external gears. One of the two machines has an extended axial travel of 1,000 mm, enabling the production of several important shaft-type parts for wind turbine gearboxes, such as sun shafts and high-speed pinions. A one-piece machine bed with excellent stiffness and dampening is the foundation for these machines’ high accuracy requirements. Excellent accessibility to the work area of the machine is achieved by doors that open wider and a counter support placed in the corner of the machine. Most importantly, the use of Gleason’s proven HSK external grinding head guarantees maximum flexibility and, thanks to the HSK quick-change system, allows the use of different grinding wheel spindles for dressable and non-dressable CBN grinding wheels in a diameter range of 40–350 mm. This has enabled Engranajes Juaristi to take advantage of the latest developments in ceramic grinding wheels that, in just the last few years, have made dramatic reductions in finish profile grinding cycle times. “It’s a testament to the Gleason machines’ design,” says Jokin Juaristi. “The machines allow us to keep up with tooling innovations that make us more competitive. While we’re just doing external gear grinding with these machines, we’re now considering adding an internal gear grinding capability. These machines are easily adaptable.” An internal grinding device can be added without removing the external grinding spindle. As a result, the machines can be configured to finish-grind a wide range of internal and external gears, as well as worms of all common types. The machines also include integrated on-board gear measurement and the latest smart dressing technology, which reduces costly, time-consuming dressing time for initial or re-profiling of a grinding wheel. The innovative software function ensures that dressing only takes place on the necessary grinding wheel areas, thus saving time.</span></p><p style="text-align: justify;"><span style="font-family: arial, helvetica, sans-serif; font-size: 12px;">Gleason provides complete tooling solutions including grinding wheels and dressing tools. Localized Service and Support Localized Gleason support has played an important role in helping Engranajes Juaristi transition its gear manufacturing from “mechanical to modern.” “It’s gratifying to work with a company where ownership is so open to the possibilities of our new technologies,” says Xavi Vallsmadella, regional sales manager, Gleason Sales Spain, who has supported Engranajes Juaristi throughout its 20-year modernization journey. “It’s an example of how a small company, with the right technologies, can do big things.”</span></p>
