The S121 universal internal cylindrical grinding machine has an exceptional price/performance ratio and is the ideal machine for internal, surface and external grinding of chuck components. It has a host of sophisticated technical features such as the revolutionary StuderGuide® guideway system, high-precision axis drives with linear motors, a swivel-in dressing unit, etc. The S121 is the ideal machine for a wide range of internal grinding applications. Many workpieces are in the areas of machine tools, drive elements, aerospace, die and mold.

Precision is the result of perfect interaction between a large number of different factors. The basis is the Granitan® S103 machine bed with its excellent cushioning and thermal behavior. The modules are ideally suited to each other and produced with the customary STUDER precision. The large distance between the guideways and the very rigidly constructed slides form the basis for the precision and productivity of this machine. All components involved in defining precision are temperature-stabilized.

StuderWIN creates a stable programming environment and contributes to efficient use of the machine. A PC is integrated into the CNC control system. The possibility of fully integrating the in-process gauging and sensor technology for process monitoring as well as contact detection and balancing systems in the control enable standardized programming of the different systems. The drive elements are optimally adapted to the control.

Studer_csm_S141

The S141 is a CNC universal internal cylindrical grinding machine of the latest generation. It has a host of sophisticated technical features such as the revolutionary StuderGuide® guide system, high-precision axis drives with linear motors, extremely fast direct drive of the grinding spindle turret, automatic swiveling of the workpiece table etc.

Three sizes are available for workpiece lengths of 300 mm, 700 mm and 1300 mm (11.8", 27.5" and 51.1"). For all models the maximum internal grinding length is 250 mm (9.8") and the external length is 150 mm (5.9"). The S141 is the ideal machine for grinding spindle shafts, spindle housings, rotor shafts, axes or flange parts. Many workpieces are in the areas of machine tools, drive elements, aerospace and toolmaking.

Precision is the result of perfect interaction between a large number of different factors. The basis of the S141 is the machine bed comprising Granitan® S103 with its excellent dampening and favorable thermal behavior. The modules are ideally suited to each other and produced with the customary STUDER precision. The large distance between the guideways and the very rigidly constructed slides form the basis for the precision and productivity of this machine. All components involved in defining precision are temperature-stabilized.

StuderWIN/StuderSIM creates a stable programming environment and contributes to efficient use of the machine. A PC is integrated into the CNC control system. The possibility of fully integrating the in-process gauging and sensor technology for process monitoring as well as contact detection and automatic balancing systems in the control enable standardized programming of the different systems.

StuderSTUDER has been writing grinding history since 1912. STUDER has developed from a small enterprise into an internationally active company with around 800 staff. Fritz Studer AG owes its position in the market to the experience gained from building more than 24,000 systems. Its former pioneering spirit is also reflected in its present-day products, and is impressively demonstrated by the quality and quantity of its innovations.
