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.
The concept and dimensions of the S41cnc cylindrical grinder are comparable with the proven S40cnc, but features some recently developed elements and modifications ready for a new generation of wheelheads and further peripheral elements.
The S41cnc is the first machine which comes with the new Studer design concept.
* Increased machine bed rigidity, optimised for workpieces of up to 180kg (396lb).

Production cylindrical grinders are fast, precise
The highly productive S-series of cnc cylindrical internal and external grinding machines offer a wide range of options, fast setting-up and high precision.
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.
* Pre-Loaded hydrostatic guideways in the X-axis (feed motion).
To the customer's advantage is the optimal dynamic behaviour for form grinding, taper grinding and interpolation grinding, combined with increased rigidity.
* Longer in X-axis travel, now 300mm (11.8in).
* Increased axis speed in X, now 15m/min (590in/min).
* Larger distance between the guideways of the Z-axis, providing more rigidity against the feed forces when plunge grinding.
* Massive layout of the longitudinal guideway.
Increased longitudinal table stability.
* Longer longitudinal slide to make sure that dressing attachments and similar equipment can be mounted.
* Longer in Z-axis travel, now 1200mm (47in).
* Increased axis speed in Z, now 15m/min (590in/min).
* The absolute length measuring systems of the axes X and Z make referencing at machine start unnecessary.
* Larger swivel radius of the B axis: I e a larger wheel-head can be installed.
* New maintenance and service-friendly enclosure concept.
* Better work area accessibility when loading from the top (i e portal loader).
* Energy supply on the Z-axis prepared for additional options.
* New control FANUC 16i or 160i.
With the control 160i, this machine is now entirely compatible with Windows applications and with both control types connections to networks via Ethernet interfaces are possible.
* Generally, actuators and sensors are connected by means of ASi-Bus.
This simplifies retrofits.
Future applications and procedures - further developments will follow, especially with regard to wheelhead layouts.
A glance towards the future of the S41cnc reveals the following: * Dual motor spindle wheelhead with up to four grinding wheels 500mm (20in) diameter.
* Integration hard turning operations, either with a single tool (only one turning operation, e g internal profile turning of an HSK taper shoulder) or by means of an indexing tool holder.
* Y-axis to grind longitudinal grooves.
* A-axis applications to grind threads with slanted pitch angles.
The S41cnc has been demonstrated hard turning and grinding a HSK63 tool holder.
