Accutom-2
Instruction Manual
Accutom-2 accepts cut-off wheels with a diameter of 50 mm (smallest
flange is 42 mm) up to 175 mm. Hole 12,7 mm.
For cutting metallic materials the fastest and most economical cut is
obtained with the Al O
2 3
specimens must not contain phases harder than 1700 Vickers, if these
phases have to be cut.
Diamond cut-off wheels are used for all harder materials or materials
containing very hard phases, carbides, nitrites etc.
For hard ductile materials like sintered carbides or nitrites diamond cut-off
wheels with bakelite bonding like 351CA are used.
For hard brittle materials such as geological materials, electronic
components or crystals diamond cut-off wheels with metal bonding 100CA,
230CA, 330CA and 551CA are used.
In order to obtain the best possible surface quality as thin cut-off wheels as
possible, with a high concentration of diamonds and small grain sizes are
used. 100CA, 230CA.
For general use and routine inspection a cut-off wheel with low
concentration and coarse grains like 330CA or 351CA are used. These cut-
off wheels, and especially 551CA, are well suited for manual cutting.
In order to obtain the highest possible accuracy as big flanges as possible
should always be used (65 mm).
Having chosen a cut-off wheel and a flange these are mounted as follows:
Turn the right cooling tube to the right in order to facilitate access to the
spindle.
Put on the inner part of the chosen flange (fig. 1.13).
The fitting between spindle and inner flange being tight, these 2 surfaces
If the inner flange does not fit directly, under no circumstances try to press it
on, as this may damage the spindle. See if there should be small burrs and
if so, take them off with grinding paper, grain size 1200.
cut-off wheels 356CA or 357CA. However, the

must be absolutely clean.
