Whether flange parts or spindles up to 1 300 mm (51.1") in length, the universal internal cylindrical grinding machines can master any challenge.

Available models
Studer_csm_S120

The S120 is based on the same machine concept as the S110, but is designed for larger and longer workpieces. The spindle set-up, with up to 3 HF grinding spindles in a linear arrangement, can be optimally designed to meet customer requirements. The ideal grinding machine for internal, face, thread and taper grinding on long workpieces up to approx. 650mm in length, e.g. for the machining of the ends of machine spindles.

Technical Data:

  • Up to three HF grinding spindles in a linear arrangement
  • Large selection of internal and external spindles
  • C axis for the workhead for form and thread grinding
  • Manual A axis for precise thread grinding
  • Various dressing options
  • Full enclosure with sliding door
  • Integrated or autonomous loading systems
  • Measuring probe
  • SimCT offline simulation software
  • Large range of accessories
  • Standardized interface for loader and peripheral devices
Studer_csm_S121

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.

Technical Data

  • Swing diameter above the table 400 mm
  • Max. workpiece length (including clamping device) 300 mm
  • Internal grinding length 175 mm
  • Maximum workpiece weight 125 kg
  • StuderGuide® guide system with linear drive
  • Spindle turret with two grinding spindles or one fixed spindle
  • C-axis for the workhead enabling form and thread grinding
  • Full enclosure with two sliding doors
  • Granitan® S103 mineral casting machine base
  • Very simple operation and programming thanks to StuderWIN
  • Short setup and resetting times e.g. with Studer Quick-Set
  • Standardized interfaces for loader and peripheral devices
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. The drive elements are optimally adapted to the control.

Technical Data

  • Swing diameter above the table 400 mm (15.7")
  • Max. workpiece length 300 / 700 / 1300 mm (11.8" / 27.5" / 51.1")
  • Internal grinding length 250 mm (9.8")
  • Maximum workpiece weight 250 kg (550 lbs)
  • StuderGuide® guide system with linear motors
  • Grinding spindle turret with up to four grinding spindles
  • Automatically swiveling workpiece table
  • C-axis for the workhead for form and thread grinding
  • Full enclosure with two sliding doors
  • Granitan® S103 mineral casting machine base
  • Very simple operation and programming thanks to StuderWIN or StuderSIM
  • Short setup and resetting times e.g. with STUDER Quick-Set
  • Standardized interfaces for loader and peripheral devices
