The STUDER S11 cylindrical grinding machine is the smallest machine in the company's portfolio and is tailor-made for workpieces of up to 200 mm in length.

Swiss grinding machine manufacturer Fritz Studer AG surprised the market at EMO 2013 with the STUDER S11 cylindrical grinding machine. The youngest S11 is the smallest machine in the Thun company's portfolio and is tailor-made for workpieces of up to 200 mm in length. This extremely compact machine concept delivers a level of productivity that will amaze even experienced grinding specialists.

The cylindrical grinding sector has not yet seen a machine of this compactness for this range of parts on the market. The company is very confident about its latest development, the STUDER S11, as the statement by Martin Habegger (S11 Project Manager) shows: "We carried out a preliminary market analysis. We are not aware of any comparable machine with the same functionalities as the STUDER S11 on the market at present. The S11 embodies an extremely compact design paired with high productivity and Swiss precision. Energy effi-ciency included and certified by the Blue Competence Label."

Twice the productivity on the same area

The following comparison shows what the new machine is capable of. Anyone who still uses a STUDER S36 today and produces parts up to a maximum length of 200 mm, can now use two new STUDER S11s on the same floor space as that required for an S36. And one S11 alone has a 15% higher productivity than the STUDER S36. In concrete terms this means: in the space taken up by one STUDER S36, two STUDER S11s can guarantee a 230 percent higher output.

Compact design - high precision

This comparison emphasizes the direction things are taking in cylindrical grinding: greater productivity combined with an extremely compact design. However, when people hear the term "compact" in the machine tool industry, the following questions are bound to be asked:
1. Is the STUDER S11 sufficiently stable and precise?
2. Is the STUDER S11 easily accessible despite its small size?

The answer to both these questions is clearly yes. When it comes to grinding, precision is the be-all and end-all. The Thun specialists naturally have this in their genes. Initial empirical values with respect to precision are provided by the manufacture of injection nozzles for die-sels. This requires roundness tolerances under 5/10 μm in series and a straightness under 1 μm. These values are considerably undercut by the S11 in practice. This is ensured not only by STUDER's precision machine tool construction and an excellent heat management sys-tem but also by the in-process gauging and the control system.

500 mm grinding wheel with rotary dressing

But what can the STUDER S11 really do? Workpieces up to 200 mm long, with diameters of 50 mm and weighing up to 3 kg can be machined on the production cylindrical grinding ma-chine with a max. floor space of 1.8 m2. The center height is 125 mm. In addition, the grind-ing machine manufacturer from Thun has managed to integrate a 500 mm diameter grinding wheel, which can also be rotary dressed, into this small machine. This is not a coincidence. 500 mm grinding wheel diameters are essential when it comes to high productivity.
