With its combination of High Dynamic
Turning and FreeTurn tooling
CERATIZIT has re-imagined turning.
High Dynamic Turning (HDT) ips conventional
turning methods completely upside down. This
new turning technology, combined with the
dynamic FreeTurn tooling, means that it will be
possible to carry out all traditional turning
operations, such as roughing, nishing, contour
turning, face turning and longitudinal turning,
with just a single tool. HDT provides a
completely uncompromising method of turning.
For 100 years, new cutting materials, new
chip breakers and a few new tooling systems
have been invented to optimise turning.
However, the actual basic turning process has
remained unchanged. Even with multi-axis
turn-mill centres, a contour is created with an
indexable insert’s cutting edge set at a xed
angle to the workpiece. CERATIZIT saw the
opportunities presented by the dynamics
of these machines and developed HDT. The
simple idea behind the development is that the
tool approach angle and point of contact can
be varied, as opposed to conventional turning,
where both are xed.
So now, instead of the classic, static position
of the insert in the holder, HDT utilises the milling
spindles 360° of freedom to produce the ideal
approach angle to the workpiece. The use of
the spindle drive, in conjunction with the slim,
axial tool design of
the FreeTurn tools by
CERATIZIT, creates
a huge degree of
freedom without
the risk of collision,
thus providing
unprecedented
exibility and
versatility. Thanks to
the rotation around
its own tool axis, the
cutting-edge change
can be done without interrupting the cutting
process. Additionally, the angle of approach
is in nitely variable at any time and can even
be changed while cutting. This enables exible
machining of almost every workpiece contour,
as well as generating optimum chip breaking,
higher feed rates and increased tool life.
Depending on the machine capabilities,
the technology can be used functionally
in all areas of turning operations. The
positioning of the milling spindle along
the Y/Z-axis on turn-mill centres creates
multiple possibilities for the use of
HDT that previously would have been
unachievable. For example, cutting
from above and below is possible.
Depending on the machining area
and workpiece size, this freedom can
be an important factor in ef cient
machining.
HDT will see the static turning
tools of the past replaced by
dynamic ones. One such dynamic
tooling solution is FreeTurn by CERATIZIT. The
de ning characteristic of FreeTurn tooling is its
simple structure. The toolholder, together with its
slim shank and axial concept that optimises the
direction of the cutting forces into the spindle,
forms a stable unit. At the front there is a multisided
insert, which is simply screwed in place.
The trick: the patent-pending FreeTurn insert can
consist of several cutting edges having different
properties. This allows for different angle points,
corner radii or chip breakers – even different
coatings and cutting materials are conceivable.
High Dynamic Turning and FreeTurn tooling from
CERATIZIT have re-imagined turning, ipping
conventional turning methods upside down
The tool can therefore be adapted to the
machining requirements, offering the advantage
of replacing several tools. This in turn leads to
signi cant savings in tool change times, tool
magazine loadouts and tools themselves. One
outstanding feature is making components with
highly complex contours without limitation using
only one FreeTurn tool. This exibility ensures
that complex component holding can be quickly
and effectively adapted to the new machining
situation.
The arrival of HDT and the FreeTurn tools
by CERATIZIT is the start of a new era in
turning. HDT generates greater ef ciency than
conventional turning many times over and it
is seen as a direct replacement for the classic
approaches as more and more turn-mill
centres are installed. Set-up time is reduced
signi cantly, as only one tool is required,
instead of multiple turning tools; non-productive
time is reduced by 90%; tooling costs are 66%
lower; and feed rates can be as much as 40%
greater than with conventional turning methods.
In addition, users will discover numerous ways
in which this new technology can improve
productivity through faster, more ef cient metal
removal. The future of turning has just begun
with HDT, and CERATIZIT developers are looking
forward to supporting their customers along this
journey together.
