The new Studer S41 CNC universal cylindrical grinding machine is characterized by outstanding technology and cost-effectiveness. The machine grinds with much higher precision, paired with a much greater metal removal rate. In addition the longitudinal and cross slide, as well as the swivel axis for the wheelhead are equipped with electric direct drives, which move to the working position much more quickly and precisely.
Higher precision, better surface quality, higher metal removal rates – these are the constantly increasing requirements made by the market on the cost-effectiveness of grinding machines in a nutshell. In fulfilling these requirements, Fritz Studer AG sets standards with its new S41 CNC universal cylindrical grinding machine. The developers used the practical know-how from a predecessor machine proven worldwide over many years, but the new machine scores with a number of outstanding design features. It works more quickly and precisely and also offers a broader range of applications, with production options that are highly attractive with regard to cost-effectiveness. And by saving on auxiliary times, it considerably shortens the cycle times of the grinding process.
Extremely rigid machine bed and maintenance-free guide system The outstanding features of the S41 include, for example, the more solid, more rigid and more thermally stable machine bed made of Granitan® S103. The new hydrostatic and hydrodynamic StuderGuide® guideway system ensures high precision of the longitudinal and cross slides when both stationary and during movement.
Electric direct drives increase speed and precision The longitudinal slide (Z-axis) has a ground work table which carries the workhead and tailstock as well as additional accessories and devices. A ground T-slot over the entire length of the guideway enables optimal positioning of dressing tools. The cross slide (X-axis) supports the wheelhead. Longitudinal and cross slides are moved by linear direct drives ( up to 20 meters per minute). The swivel movement of the turret wheelhead (B-axis) is also by a direct drive. It swivels the turret wheelhead around three times faster and positions the new grinding wheels in a much shorter time with a positioning range of < 1".
Machine variants expand market potential for users In addition to the considerable increases in working speed and precision, the S41 also has a number of advantageous characteristics which enable the user to cover an extended workpiece range, and thus a broader market range:
- Height of centers on the standard version has been increased to 225 millimeters.
- The machine is also optionally available with a height of centers of 275 millimeters
- Maximum distance between centers is 1000 millimeters on the standard machine
- Variant with a distance between centers of 1600 millimeters is also available.
- The machine is equipped with a hydraulically clamped tailstock for the heavier workpieces.
- Up to four external grinding wheels or three internal grinding spindles enable over 30 grinding head combinations.
- The grinding wheels are no longer driven by belt drives, but only by motor spindles.
- The machine can also be equipped with motor spindles for high speed grinding (HSG).

Promising results This machine was presented to the Studer’s network earlier this year and unveiled widely at EMO. At the show we met Ms. Fahrni responsible for communication with Studer; she told us that the S41 sales started well and that first users are very satisfied with the machines. Marketing message? Certainly but the facts are there, these machines are "far better" than the previous ones and the markets react well.
