Grinding of thin sections
The thickness ground during each differ-
ent operation associated with a thin sec-
tion can be easily adjusted or even saved
in different grinding methods. After grind-
ing the glass plate to the precise thick-
ness, the position of the sample holder is
set to zero. Thereafter the thickness of the
thin section is entered directly.
Target grinding in components
When the precise position of a com-
ponent within a sample is known,
Accutom-50 can be programmed to
grind down to precisely that position.
The position can be adjusted in steps
of 5 µm.
Variable cut-off wheel speed up to
5000 rpm
The variable cut-off wheel speed can
be adjusted from 300 up to 5000 rpm
in steps of 100 rpm. This grants even
higher precision as the drift of the cut-
off wheel is reduced because of the
higher speed. Also, the feed speed can
be increased without experiencing any
deterioration in the high quality of the
cut surface.
Database for both cutting and
grinding methods
Accutom-50 is equipped with a data-
base capable of storing 20 cutting and
10 grinding methods.
Improved menu control
Subsequent menus for the selection of
cutting or grinding parameters greatly
facilitate the operation. Together with
the larger display the new menu control
improves the user-friendliness of
Accutom-50.
Cut-off wheels
As Accutom-50 works with program-
mable constant feed speeds, all types
of cut-off wheels, including abrasive
wheels, can be used.
Struers offer a large variety of Diamond,
CBN, Al

and SiC cut-off wheels
cove-ring all possible applications.
Also, saw blades for the cutting of very
soft metals or plastics can be used on
Accutom-5/50 due to the cover with the
safety switch.
Cup wheels
Two different types of cup wheels,
resin and metal bonded, are available
for grinding on Accutom-50.
Specimen holders
All specimen holders for Accutom-5/-50
are provided with a dovetail plate.
This means that the samples can be
clamped into the sample holder outside
the cutting chamber, and then easily
inserted into the dovetail fixture of
Accutom-5/-50.
Grinding on Accutom-50 can be carried out in two
different ways: The grinding operation can be stopped at
a specified position, or a well-defined amount of material
can be removed
A wide range of specimen holders can
be used on Accutom machines
