STUDER’s S36 grinding machine

Due to the rapid development of e-mobility and other alternative drive types, the demand for suitable grinding machines for a new variety of components in vehicle manufacture is also increasing. That’s why STUDER developed the new S36. It will be positioned between the compact S11 for small workpieces and the S22 for medium-sized workpieces. Many features of the new S36 are similar to its predecessor, which sold over a thousand units. New functionalities for changing requirements supplement proven concepts.

“The demand for cost-effective grinding solutions for medium to large series also remains consistently high in e-mobility applications”, says project manager Martin Habegger. In addition to vehicle manufacture, the machine will be used in the hydraulic, pump and toolmaking sectors.

The S36 has a fixed grinding head, with grinding wheel angles of 0, 15 or 30 degrees available. The distance between centers is 650mm and the maximum workpiece weight is 150kg. Proven components were used in the machine, including a Granitan machine bed and a workhead with high-precision roller bearings.

Range of parts/market segment
The machine concept is designed for productive external grinding of chuck and shaft components.

Its field of application extends from die and mold through the aerospace industry to the production of parts for the hydraulic and automotive industry.

State-of-the-art grinding technology for optimum price/performance
An outstanding feature of the new machine is its large grinding wheel, which has a diameter of 610mm and initially a maximum width of 125mm. This makes the S36 above standard in its category. In addition, the machine comes with C.O.R.E. OS, the UNITED GRINDING Group's smart, cross-brand operating system – including touch panel and intuitive operation. Thanks to the uniform C.O.R.E. software architecture, data exchange between the machines is easily possible. This is also possible with third-party systems via the integrated umati interface. This interface also provides access to the UNITED GRINDING Digital Solutions™ products directly at the machine and without the installation of additional hardware. C.O.R.E. creates the technical foundation not just for these and other IoT and data applications, but also for a revolutionary, standard, and simple mode of operation.

The newly developed SmartJet nozzles for efficient and automatic coolant supply are fitted as standard. Thanks to these, cooling is now managed by the machine control. A frequency-controlled pump and a dynamic pressure measuring unit are used as central components. These make it possible to precisely adjust the volume flow to suit the process – for rough grinding, fine grinding, or finishing. The cooling medium is fed to the grinding wheel via a manifold and flow-optimized, adjustable nozzles.

“This concept guarantees precise, efficient and reproducible cooling”, emphasizes Martin Habegger. “We offer customers the S36 with all of this modern grinding technology at an excellent price/performance ratio.”
