Due to the rapid development of e-mobility and other alternative drive types, among other things, the demand for suitable grinding machines for a new variety of components in vehicle manufacture is also increasing. That is why STUDER has 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 very successful 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 new machine will also 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 have been used in the machine. These include 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.
STUDER serves many different industries with the S36. 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 610 mm 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”, says Habegger.
Related Glossary Terms
Cone-shaped pins that support a workpiece by one or two ends during machining. The centers fit into holes drilled in the workpiece ends. Centers that turn with the workpiece are called “live” centers; those that do not are called “dead” centers.
Workholding device that affixes to a mill, lathe or drill-press spindle. It holds a tool or workpiece by one end, allowing it to be rotated. May also be fitted to the machine table to hold a workpiece. Two or more adjustable jaws actually hold the tool or part. May be actuated manually, pneumatically, hydraulically or electrically. See collet.
Fluid that reduces temperature buildup at the tool/workpiece interface during machining. Normally takes the form of a liquid such as soluble or chemical mixtures (semisynthetic, synthetic) but can be pressurized air or other gas. Because of water’s ability to absorb great quantities of heat, it is widely used as a coolant and vehicle for various cutting compounds, with the water-to-compound ratio varying with the machining task. See cutting fluid; semisynthetic cutting fluid; soluble-oil cutting fluid; synthetic cutting fluid.
Machining operation in which material is removed from the workpiece by a powered abrasive wheel, stone, belt, paste, sheet, compound, slurry, etc. Takes various forms: surface grinding (creates flat and/or squared surfaces); cylindrical grinding (for external cylindrical and tapered shapes, fillets, undercuts, etc.); centerless grinding; chamfering; thread and form grinding; tool and cutter grinding; offhand grinding; lapping and polishing (grinding with extremely fine grits to create ultrasmooth surfaces); honing; and disc grinding.
- grinding wheel
Wheel formed from abrasive material mixed in a suitable matrix. Takes a variety of shapes but falls into two basic categories: one that cuts on its periphery, as in reciprocating grinding, and one that cuts on its side or face, as in tool and cutter grinding.
