United Grinding’s Studer S141 universal ID cylindrical grinding machine that offers the ability to internally grind longer workpieces common to the machine tool, drive element, aerospace and toolmaking industries. The S141 combines both cutting edge and proven technologies with optimal ergonomics and ease of use, while delivering dependability, quality and precision.

The S141 features two big sliding doors for optimum accessibility and is available in three different design sizes to machine workpieces with maximum lengths of 11.81" (300 mm), 27.56" (700 mm) and 51.18" (1,300 mm) and inside diameters up to 9.84" (250 mm). These grinding capacities make the S141 especially useful for processing chuck components, spindle shafts, spindle housings, rotor shafts and other such parts.

The S141’s grinding spindle turret accommodates as many as four grinding spindles (including a maximum of two external grinding spindles), a universal measuring probe and internal grinding quills in lengths up to 10.433" (265 mm). This allows both internal and external machining of workpieces in the same clamping, minimizes non-cut times and boosts part accuracy. With a direct-drive integrated swivel axis and high resolution measuring system, the turret rotates/positions quickly and precisely for a repeatability of less than one angular second. 

In addition to a workhead that can be direct or belt driven, the S141’s workpiece table automatically swivels from -10 to +20 degrees via the machine control for axis parallel grinding of tapers. Up to two pivoting dressing units for fixed or rotating dressing tools mount on the machine and ensure the grinding wheels stay sharp throughout the machining operations to provide maximum performance and process stability.
