New Cylindrical Grinding Machine

Oct. 20, 2022
The S36 machine is designed for external grinding of chuck and shaft components, for automotive components – including alternative drive systems – as well as die-and-mold production, toolmaking, aerospace components, and parts for hydraulic and pump.

UNITED GRINDING has developed the new Studer S36 cylindrical grinding machine in response to the demand for a new range of automotive components, resulting from the rapid development of e-mobility and other alternative drive types.

The S36 will be positioned between Studer’s compact S11 for small workpieces and the S22 for medium-sized workpieces, noting in its announcement that “new functionalities for changing requirements supplement proven concepts.

“The demand for cost-effective grinding solutions for medium-to-large series remains consistently high in e-mobility applications,” said Martin Habegger, project manager at Studer.

The S36 machine concept is designed for productive external grinding of chuck and shaft components, for many different industries. Its field of application ranges from die-and-mold production to toolmaking, to aerospace components, to parts for the hydraulic and pump systems.

The S36 has a fixed grinding head, with grinding wheel angles of 0, 15, or 30 degrees available. The distance between centers is 650 mm (25.6 in.) and the maximum workpiece weight is 150 kg (330 lbs.) Other established, Studer machine design details, including a Granitan® machine bed and a workhead with high-precision roller bearings, remain in the S36.

A noteworthy feature of the new S36 is its large grinding wheel, which has a diameter of 610 mm (24 in.) and a maximum width of 125 mm (4.9 in.) This makes the S36 a standout in its category. In addition, the machine comes with the C.O.R.E. operating system, which includes 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 for these and other IoT and data applications, but also for a standard and simple mode of operation.

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, so it’s possible to adjust the volume flow precisely, 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,” Habegger said. “We offer customers the S36 with all of this modern grinding technology at an excellent price-to-performance ratio.”
