Tangential roughing tools TSW
The MAPAL tangential roughing tools set new standards
in relation to stability and performance, particularly in the
case of higher stock removal. An innovative, six-cutting
edge indexable insert with special support chamfer prevents
chatter and vibration. Perfect multi-cutting edge capability
with increased stability is ensured by the tangential
installation of the indexable inserts in precision insert seats
on the front face.
Tangential roughing tools
Series
TSW 101/111 and TSW 201/211
The ground clamping geometry combined
with the tangential installation position on
the face of the tool body results in a highly
positive rake angle and therefore a soft cut
and very quiet tool cutting behaviour. This
property is further supported by a special
support surface on the cutting edges, an arc
shaped land, which supports the tool in the
bore like an arc land chamfer on reamers.
Along with the excellent cutting behaviour of
the tangential roughing tools, the necessary
drive power required is also reduced, as the
machining forces are comparatively low. As a
result the tools can also be used on machines
with lower torques. It is, however, much more
important that, with the same drive power,
it is possible to fit more cutting edges to the
tools, so that the feeds are increased and
machining times drastically reduced.
The diameter range of the tools from the
standard series is 37 - 280 mm; larger
diameters are also possible as a custom
solution. Two insert sizes available in
different substrates cover the entire diameter
range.
The TSW are available in a monoblock design
and as a modular system for larger diameters.
The TSW tools are also designed with two
different contact angles on the insert seats.
The contact angle is 0° on the TSW 101/201
tools for blind bores and 10° on the TSW
111/211 tools for through bores.
