The New STUDER S100: The Perfect Entry-Level Grinding Machine

MIAMISBURG, Ohio, Tuesday November 15, 2022 – STUDER, a brand of UNITED GRINDING, presents the new S100. This high-precision, flexible and reliable universal internal cylindrical grinding machine is ideal for the entry-level market. Its excellent price-performance ratio makes it perfect for a wide range of internal grinding applications. “The S100 perfectly complements our comprehensive internal grinding portfolio”, explained STUDER CSO Sandro Bottazzo when presenting the S100 at the BI-MU Exhibition in Milan.

Like all STUDER cylindrical grinding machines, the S100 has a machine bed made of Granitan®. The outstanding dampening and thermal characteristics of this material ensure consistently good grinding results and help provide the renowned STUDER precision. During the development process, special attention was given to designing components that are uncomplicated and efficient, making operation and maintenance easy for the operator. Despite this straightforward construction, the features built into the S100 make it suitable for grinding geometrically defined basic forms and contours for a wide range of parts, all of which can be generated with the machine’s interpolating axes.

The S100 can be configured to meet each customer’s individual needs. It can be equipped with up to two internal grinding spindles, or one internal and one external spindle. In addition to a fixed wheelhead, it can be supplied with a manual wheelhead and a 2.5 degree Hirth coupling. The optimal combination consists of an automatic wheelhead with a 1 degree Hirth. A synchronous motor drives the grease-lubricated internal and external belt spindles. The machine is operated by the FANUC 0i-TF PLUS controller, together with the proven STUDER operating system.

A further advantage of the S100 is the available automation equipment options. The machine can be ordered with a loading interface and an automatic sliding door, enabling automatic operation for large production runs.

Typical workpieces for production on the S100 include collets for toolmaking, bearing rings, ball bearings and cylinders, as well as hydraulic control valves in small runs. External and internal machining of flange parts or grinding of threads or non-circular forms are also possible.

As always, the competent and reliable STUDER Customer Care service is close at hand to provide advice and technical support. “A total of more than 200 specialists worldwide ensure that the S100 will operate reliably and efficiently throughout its entire lifetime and fully satisfy all requirements,” Bottazzo said. “Customers can rely on the 110-year grinding tradition of STUDER.”
