Studer S100 Grinding Machine For High-Precision, Flexible, Reliable Grinding

United Grinding’s Studer S100 CNC universal internal cylindrical grinding machine offers the Studer quality and high precision in standard internal cylindrical grinding operations at a good price-performance ratio. It covers a wide range of internal, surface and external grinding applications, making it well suited for the entry-level segment.

The machine is designed to provide high-precision, flexible and reliable grinding. It has a workpiece length including a clamping device maximum of 550 mm (21.65") and a workpiece diameter maximum of 420 mm (16.53"). Many suitable workpieces can be found in the compressor, hydraulic, machine tool, aero-space and tooling industries.

“The S100 internal grinding entry-level machine perfectly complements our comprehensive internal grind-ing portfolio,” says Sandro Bottazzo, Studer CSO. 

Like all Studer cylindrical grinding machines, the S100 also has a machine bed made of Granitan. The com-pany says its oustanding dampening and thermal characteristics ensure consistently good grinding results and precision. During development, special attention was given to a simple and efficient design of the components, making operation and maintenance easier for the operator. However, the equipment of the S100 also makes it suitable for grinding a varied spectrum of parts, including geometrically defined basic forms and contours, which can be generated with interpolating axes.

This flexible equipment works on a diversity of parts. The machine 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 equipped with a manual with a 2.5 degree Hirth and, in its optimum configuration, with an automatic wheelhead with 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 Studer operat-ing system.

A further advantage of the S100 is the automation option. On request, it can be equipped with a loading interface and an automatic sliding door, enabling automatic operation and the production of large series. 
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 series. External and internal machining of flange parts or grinding of threads or noncircular forms is also possible.
