Tangential fine boring tools TFB
Tangential technology now also for fine machining. Newly
developed reaming cutting edges are mounted in precision
insert seats and set sensitively and highly accurately to a
defined amount above the reference setting pads using the
MAPAL wedge adjustment.

The tool is guided in the bore by the special arc shaped
land. The MAPAL TFB series impresses due to easy, precise
handling, quiet running at high feeds and the best
machining results.

The tangential fine boring tools are far
superior to the previous conventional tool
systems for the fine machining of large
diameters. Compared to one or two-cutting
edge boring tools the TFB tools are six to
eight times faster with machining results in
reaming quality.
During fine machining the effect of the arc
shaped land is even more significant than
on the roughing tools – it guides the tool in
the bore and at the same time smoothes the
surface. The TFB tools are equipped with six
to eight indexable inserts that are embedded
in the tool body unevenly in relation to each
other.
The reaming cutting edges are mounted
in precision insert seats; a MAPAL wedge
adjustment feature for exact and very
sensitive adjustment is fitted for each cutting
edge. Precision ground reference pads are
used as a setting aid. The setting of the tools
is enormously simplified, as the cutting edge
only needs to be set to a specific amount
beyond the pad diameter, a task that is very
easy using commonly available measuring
equipment and the sensitive adjustment
accurate to the μm (see setting instructions
on page 178).
The TFB tangential fine boring tools comprise
of three assemblies. The machine adapter and
the intermediate adapter are connected via
a MAPAL Module connection with radial and
axial alignment, as a result the radial run-out
error on the spindle can be compensated.
The tangential fine boring head is connected
to the intermediate adapter via an HSK
connection. The standard diameter range is
from ø 60 to 280 mm.
The TFB tools are available in two different
series. TFB 101 for blind bores and TFB 111 for
through bores.
