Granitan S103, as used
at present for the Studer machine bases has excellent
physical properties and presents essential advantages
to other materials such as: -
 Excellent
dampening properties
Granitan S103 has 6 - 8
times better dampening properties than cast iron. This
allows you to get better grinding finishes an higher
speeds. |
|
 |
Excellent
thermal properties
The following curve
illustrates the advantage of the 3 times greater
temperature-time constant of a Granitan base in
comparison to grey cast iron. Granitan reacts to short
term temperature changes, based on environmental
influences and the grinding process itself, much
slower and much less. This feature gives the machine
an unbeatable 'tolerance holding' capability
throughout the whole day.

 |
Favourable
chemical properties
Another advantage
Granitan S103 has over other machine base materials is
the chemical resistance against cooling-lubricant,
cutting oil and detergents. There is no risk of
corrosion or damage from coming into contact with
these liquids. |

Because of the extra rigid machine base made of
Granitan, no particular foundation is needed. Simply
place it down and it is ready to go! |
Guide ways
Studer's patented 'knopped' guide ways made of
Granitan S200 are so precisely aligned that
straightness values of less than 2.5 per 650mm length
in the cylindrical grinding process can be achieved.
The slides move on the 'knops' at an almost linear
power-speed ratio, thus positively influencing the
control of the axis. The slide does not even float at
rapid traverse speeds. |
