Metal
Broaching
Machines
Broaching is a process of machining a surface with a special tool called a Broach.
A
broach
is
a
tapered
bar
into
which
teeth
have
been
cut
so
as
to
produce
a
desired
contour
in
a
work
piece
by
a
single
pass
or
stroke
of
the
broach.
The
broach
has
three
types
of
teeth
namely
Roughing
teeth,
Semi
finishing
teeth,
finishing
teeth.
The
broach
is
pushed
or
pulled
through
a
hole
or
over
a
surface
to
remove
metal
by
axial
cutting.
Because
broaches
are
mult
toothed
cutters
produced
to
close
tolerances,
they
are
expensive,
consequently,
the
process
usually
is
employed
only
for
high
production
Broaching is
a
modern
method
of
metal
removal
that
has
almost
unlimited
applications
in
metal
working.
It
can
also
be
used
as
a
method
to
work
Wood,
Hard
vulcanized
fiber,
Hard
rubber
Graphite
and
some
plastics.
