Internal grinders machine flexibly
within microns
Safety critical machining of fuel injection components in large series, or universal machining of small series, always within tolerances of a few microns: these are the jobs for internal grinders.
Safety critical machining of fuel injection components in large series, or universal machining of small series, always within tolerances of a few microns: these are the jobs for Studer internal grinding machines, which are built in different versions On the S145cnc with up to four spindles, for instance, complex components in small and average series can be ground economically

Precision dosing ups CBN/diamond wheel life
Using a biomedical engineering micro-dosing technique, CBN and diamond coated honing tool lives can be increased up to 10 to 20 times, while grinding performance can be quadrupled.
Modular platform concept is the user's advantage
In many industrial fields, including the automobile industry, product platforms have been used successfully for several years, it has now been applied to cylindrical grinders.
Featuring a centre height of 175mm a maximum grinding length of 200mm and a substantial table load, the machine is suitable for a wide range of applications.
Grinding spindles according to requirements of 24000 rev/min to 120000 rev/min installed on the indexing turret head allow high-accuracy machining of bores up to diameters of 200mm and the manufacture of smallest bores of less than 3mm in diameter.
This is the ideal machine for the production of small and average series as well as for mould making applications.

Cylindrical grinder ready for next generation
Increased machine rigidity, longer X-axis travels and higher speeds and the capability of taking larger wheelheads, feature a new versatile cylindrical grinder.
For internal production grinding, the S140cnc is available.
Based on its modular concept, this machine is suitable for a large number of production tasks.
The standard version is equipped with hydrostatic guide-ways; this basic version of the Studer S140cnc provides the ideal basis for high accuracy machining.
Simple machining tasks with one grinding spindle can be achieved by means of the S140 modular kit, as well as complex elements including simultaneous external and internal machining.
Reductions of cycle times of up to 40% can be obtained.
Specially adapted machining modules, such as internal and external grinding spindles, workheads and different dressing attachments, can be installed on the standardised machine table according to requirements.
The machine tables with hydrostatic guide systems, in conjunction with the optional, also hydrostatically- operated drive spindle guarantee a smooth motion and perfect surface quality of the workpiece.
Up to three internal grinding spindles with ceramic bearing systems and speeds above 100,000 rev/min installed on a slide allow machining of extremely small bores to the narrowest tolerances.
Roughing and fine machining can be carried out without time-consuming indexing of a revolver.
Simultaneously to internal rough grinding, finish grinding of external diameters or surfaces can also be done.
The installation of a handling system with integrated gauging and palletising units converts the S140cnc into an unmanned machining centre.
In three shifts and seven days a week, elements for diesel injection systems, for instance, in highest quality, can be machined.
Production rates are of many 100,000 components per year.
