HEADLINE HEADLINE UNIVERSAL INTERNAL CYLINDRICAL GRINDING MACHINES A member of UNITED MACHINING SOLUTIONS

STUDER S131/S141/S151 IN USE The S131, S141, and S151 CNC universal internal cylindrical grinding machines make up a comprehensive series designed for all internal grinding applications. Whether it’s flange parts, spindle shafts, spindle housings, rotor shafts, or bushings – wherever maximum precision and efficiency are essential, these machines deliver the ideal solution. With their advanced technology, they set new standards in both precision and cost-effectiveness.

THE UNIVERSAL MODELS The S131/S141/S151 covers a wide range of internal cylindrical grinding operations. With three machine lengths and three swing diameters available, the right machine can be configured for any application. The machines handle workpieces up to 250 kg (550 lbs) in weight and 1,300 mm (51.2") in length. The S131 has many technical refinements, with its strong point being the manufacture of flanged parts and relatively small workpieces. With its three sizes, the S141 is ideal for the grinding of spindle shafts, spindle housings, rotor shafts, and flange parts. With its two sizes,...

StuderWINOPERATOR INTERFACE The user interface StuderWIN creates a stable programming environment and contributes to efficient use of the machine. The possibility of fully integrating the in-process gauging and sensor technology for process control as well as contact detection and automatic balancing systems in the operator interface enables standardized programming of the different systems. The software of an optional loading system is also integrated. The drive elements are optimally matched to the control system. The sophisticated mechanical engineering concept of the S131/S141/ S151 is completed...

GRANITAN® S103 MINERAL-CAST MACHINE BASE STUDERGUIDE® IN LONGITUDINAL AND CROSS AXIS The material structure developed by STUDER on the basis of the company’s own formula, which has proven its worth over many years, is produced in a plant using the most modern industrial techniques. The excellent damping properties of the machine base ensure that an outstanding surface quality is achieved in the ground workpieces. The service life of the grinding wheel is also increased, leading to reduced downtimes. Temporary temperature fluctuations are largely offset by the favorable thermal behavior of Granitan®....

WHEELHEAD The wheelhead with integrated swivel axis permits the use of up to four grinding spindles (of which maximum two external grinding spindles) and a universally useable measuring probe. The swivel axis has a direct drive capable of rapid and precise positioning. The high resolution direct measuring system guarantees a repeatable positioning accuracy of <1". This allows workpieces to be machined completely in the same clamping and with minimum processing times as well as the highest precision at the same time. ■ Wide range of grinding spindles ■ Change of external grinding wheel in just...

WORKHEAD The workheads can be mounted on a swiveling table with adjustable positioning. The automatic swivel axis has a swivel range of -10° to +20°. Automatic swiveling allows cylinders and various high-precision tapers to be ground in a single clamping, even parallel to the axis. The machine’s design ensures optimal accessibility for the operator, whether for changing workpieces, dressing, or changing the grinding wheel. A variety of workheads are available, all equipped with air lift-off to simplify repositioning during setup and resetting. STEADY RESTS Adjustable for long workpieces Four...

DRESSING An easy-cutting grinding wheel is essential for cost-effective and highquality grinding. Rotary and stationary dressing tools can be mounted on two swiveling units. This enables a flexible, optimized dressing process that can be precisely adapted to the specific characteristics of the workpiece, tool, and material. The grinding wheel profile and dressing parameters are easily defined via macros. Another STUDER speciality is the grinding wheel reference points (T-numbers). This enables programming with normal dimensions, which considerably simplifies the programming of grinding programs....
