Studer S22
The new production platform for
cylindrical grinding
Following the introduction of the
S12 and
the S242, STUDER have come up with
another
 innovation.
But the S22 is more
than just a machine. It is based on a platform and,
thanks to its modularity, can be configured with the
desired STUDER components for almost any
grinding application.
The
S22
production platform is completely focused on the customer
and his workpieces. Although the basic dimensions are
given, any configurations are possible. In respect of
components such as workhead and wheelhead or tailstock,
all parts that STUDER has ever developed and produced are
available on the
S22.
The platform also has no fixed distance between centres.
This is between 650 and 1100mm, depending on
configuration. Naturally the
S22
is suitable for universal
cylindrical grinding in the production environment, high
speed grinding (HSG) or heavy duty applications.
Head of development Reto Zwahlen
explains "With our new development we cover all options
offered by our proven
S36, whilst
providing additional benefits through larger grinding
lengths, rotating dressing devices and much more. The
features of the S32
(the S32 is specialised in high speed grinding) are also
incorporated into the
S22. Also, StuderWIN, STUDER's
new Windows based operator interface, offers many new
advantages." The
S22
is equipped with a Fanuc 310i-A CNC control with
integrated PC".
Configuration of
the machine
Studer is also breaking new ground
with the configuration. An overview which contains a
functional diagram of the basic machine with all
possible component variations, ensures transparency in
the decision-making phase. The customer can thus discuss
the options internally and make a preliminary selection.
The requirements are then verified in detail with
Studer's professionals and the optimal solution
developed jointly.

Machine design
and drive
All S22 versions have the proven
GRANITAN® machine bed with its excellent damping
characteristics and thermal stability. The X and Z-axis
are designed as a cross slide, while the workpiece table
is bolted permanently to the machine. Two different axes
drive systems
are available for the
S22. The X-axis is equipped
with roller guideways as standard, and the Z-axis has a
guideway with patented surface structure. The drive is
provided by a ball screw spindle. For the highest
dynamics and precision, STUDER offers an alternative
with direct drive and friction-free guideways in both
axes. The hydrostatics and linear motors allow axis
movements up to 30 m/min. Precision to a tenth of a
micrometer is easily achieved, thanks to the measuring
system resolution of 0.01um.

 Assemblies
Chuck or universal workhead, standard or high-precision
C-axis (position and speed controlled for form and
thread grinding), belt or motor spindle wheelhead,
standard, synchronous or fine grinding tailstock,
dressing from the rear with a wide variety of devices
etc. - the broad selection meets every possible
requirement. An integrated measuring system for
measuring during the grinding process, for re-measuring,
recording, evaluation and correction guarantees
comprehensive quality control.
For high-speed grinding there is a B-axis with two
grinding spindles in versions left/left or right/left
for ø 400mm wheels in the cutting speed range between 80
and 140 m/s. Heavy-duty applications with a 160mm wide
grinding wheel are also possible.
Automation
There is also a large range of loading and unloading
systems. The machine can be charged on both sides or
from above, and is ideal to be linked. Appropriate
peripheral units guarantee seamless integration into the
respective production process.
