2. Choice of tools
The design and dimensions of the component decide
the diameter and length of the boring bar.
• First choice for best clamping rigidity is the Coromant
Capto ® coupling or split sleeves.
• Select the largest possible bar diameter for the appli-
cation to achieve the best possible stability.
• The diameter of the bore and the length needed to
reach the bottom will indicate what type of boring bar
should be used.
Clearance between the boring bar and the inside of the
bore is extremely important for chip evacuation and
radial deflection. See the Main catalogue under D
m
min
(minimum bore diameter) for recommendations.
Example
For bore diameter 100
mm the applicable bar
is 80 mm. This gives
enough clearance for
chip evacuation and will
eliminate any damage of
the tool.
