The newly developed tool series for the pre-machining of outer and inner
gear production, is the result of the optimization of negative and double-
positive tangential cutting edge geometry. At the root of the tooth, the
negative insert provides the stability necessary to implement high feed
rates thus realizing a high chip removal rate. The negative insert has an
inclined bore. With the inclined position of the insert screw a higher depth
of thread is achieved, which stabilzes the insert pocket and thus the whole
tool. The double-positive tangential insert allows for a smooth cutting
process at the flank of the tooth, which reduces the axial force enormously.
The exact positioning of inserts for each individual cutting process
provides a vibration-free performance of the cutter. It is certainly possible
to produce alternative profiles according to customers' specifications.
When premachining pinions with a low amount of teeth, it may be more
economical to use a tool which complies to the involute shape with
protuberance inserts. Tools such as these can be supplied in special design.

NEW GENERATION OF GEAR GASHER WITH COOLANT CHANNEL
Roughing gasher with coolant channel
In addition to the positive cooling effect the chips are either blown or
flushed away from the operation area which has an enormous influence on
the tool life of the inserts. Another advantage is the lower degree of
warming of the workpiece during the machining operation which has
a positive effect on the quality of your product.
Innovative technology thanks to Tungaloy!
For a long period of time Tungaloy Corporation has produced milling and
boring tools with internal coolant supply. These positive experiences were
reason enough to develop a coolant supply (air or emulsion) for the various
gear gasher types as well. The coolant channels are positioned in the tool in
such a way that the respective medium cools the insert directly.

FINISHING GASHER SOLUTIONS (INTERNAL & EXTERNAL)
General Description
The finishing of gears has been practiced successfully with Tungaloy tools
for many years now. For the finishing operation all over the world tools with
a convex (internal gear production) or concave (external gear production)
form are applied. The tools, as well as the inserts are within very narrow
tolerances to achieve the required accuracy of the tooth gap. During the
machining of the tooth gap, a lot of material is removed from the tooth
base, whereas in the involute area rather a finishing operation and
polishing of the surface are carried out.
This complex machining operation was reason enough to develop a tool
concept suitable for the various cutting requirements. The result is a tool
with different radial angles as well as overlapping insert geometries.
These new tools obtain fully effective teeth at the root of the tooth and
half effective teeth at the tooth flank thus optimizing the chip thickness.
The advantages of this Tungaloy design are reflected in a longer tool life,
improved surface finish, lower heat development on the component, as
well as in a reduction of the cutting material costs.

HOB SOLUTIONS
The Tungaloy hobs are the result of continuous further development by our
engineers. The experience and individual requirements of our customers
were carefully included in the development and conception.
These tools allow an economical machining of gears from module 6 and
upwards. With the application of carbide inserts a high chip removal can
be achieved at high cutting speeds.
Tungaloy hobs consist of individual segments which are positioned by
means of high-precision cross slots. Large fitting surfaces allow us form-
fit support of each segment in the spiral. These segments are connected
with clamping screws via two end caps. Because a 360° spiral forms a
segment, the production tolerances within one rotation are minimized,
which has a positive effect on the quality class of the hobs. The Tungaloy
segment design makes an extension of the tool - an enlargement of the
cutting length – comparatively simple. Only longer pull bars are required.
Moreover, easy assembly and disassembly is guaranteed.
With the further development of the insert with an inclined bore the problem
of exchanging an insert has also been solved. It is now possible to exchange
the insert with a standard screwdriver while the hob is assembled. A further
advantage is that the position of the insert can be exactly defined because
of the inclined bore. The insert can no longer be inadvertently assembled
incorrectly. Furthermore, a larger thread percentage contact area can be
achieved thanks to this inclined position of the insert screw which stabilizes
the insert pocket as well as the tool itself.

INDEXABLE INSERT GEAR SHAPER 74X8D
General Description
Gear shaping has been an established machining process for generating
gears since the mid-twenties of the last century. Gear shaping is one of the
most widely used machining methods for producing gearwheels. It is
indispensable for the production of gearing on certain workpiece geome-
tries and on shoulders, but also for special applications,
such as non-round contours.
Despite the limited productivity compared to other gearing methods such
as hobbing, new developments have been made in the process enginee-
ring, machinery, tools and technology areas, which considerably improve
the economic efficiency and quality of the process.
To date, however, very little, if anything, has changed on the used gear-sha-
ping tools, except for the accuracy and the materials. Gear shapers made of
HSS, and to a lesser degree, solid carbide gear shapers are still used.
Disk-type shapers (DIN 1825), bell-type shapers (DIN 1826) and shank-type
shapers (DIN 1828) are used, whereby the disk-type shapers are used most
often. New to the tool concept is the use and presently unique application
of indexable inserts for this machining process.
These tools were primarily designed for roughing, i.e. gashing ready for
finish-shaping or finish-grinding. Gearwheels with low quality
requirements can be finish-shaped, within limits.
The gear shaping method is generally used whenever index milling or
hobbing is not possible. Straight- and helical-toothed, internal and
external spur gears can be produced using the gear-shaping method.
From an economic point of view, gear-shaping comes in third, after
hobbing and index milling.

Herringbone gearingExternal gearing with shoulder
From an economical point of view, however, it is the most universal of all
methods, as in addition to 'normal' external and internal gearing, it can
also be used to generate other gears, which, due to their geometry, cannot
be produced with the aforementioned methods, such as:
• External and internal gearing with shoulders
• External and internal herringbone gearing
• Gearing with thrust surfaces
• Component-related interference contours
• General gearing that does not permit an overrun of a side and face
mill or a hob, so called collision gearing.
When all is said and done, the gear shaping method can be used to
generate every type of gear that can be generated using the hobbing or
index milling method, but conversely, this is only possible to a limited
degree.
The new gear shapers are generally designed for roughing, i.e. gashing in
preparation for finish-shaping or finish-grinding. Lower gear qualities of
up to max Q8 have been achieved, but cannot be generally guaranteed,
as workpiece qualities do not allow any conclusions to be drawn about
tool qualities. At present, the tools approximately correspond to class B
according to DIN 1829.
Profiles are standardly produced to reference profile II and reference profile
III standards, as defined in DIN 3972.

General Description
Development of gear skiving has been started at the beginning of the
twentieth century. The new machining process for production of gears was
then applied for a patent by Wilhelm von Pittler in 1910. Although gear
skiving promised great potential in terms of productivity and flexibility, it
was not successful in practice and was forgotten. The technical possibilities
of that time were not yet available in the areas of machine control and
tool performance for this high-performance machining process. Thanks to
enormous progress in both machine tools and tools, thanks to modern cut-
ting materials and coatings, gear skiving is now suitable for serial production
and promises to be an interesting alternative to the established machining
processes such as hobbing and gear shaping
Gear skiving is a continuous cutting process for the production of so-called
rotationally symmetrical periodic structures, primarily gears. The skiving
tool and the work gear rotate with crossed axes according to a helical gear
pair. With the helical gear pairing, the movement is divided into a rolling
and a screwing part, which becomes a sliding cutting movement when
skiving. The larger you choose the cross-axis angle, the more the rolling
component decreases and the screwing component increases, which leads to
an increase of cutting speed. Cutting speed can only be varied by changing
axis arrangement and speed of tool and work gear. Skiving tool and work
gear receive rotary movements that are related to each other in the ratio of
the number of teeth z2/z0. The cross-axis angle ∑ is equal to the difference
in the case of opposing flank directions; in the case of flank directions in the
same direction, it is equal to the sum of the helical angles of skiving tool 0
and work gear 2.
59
∑ : cross-axis angle
β0 : helical angle of tool
β2 : helical angle of gear
v2 : cutting speed work gear
v0 : cutting speed tool
vs : resulting cutting speed
In simple terms, gear skiving can be viewed as a combination of
hobbing and gear shaping, combining some of the advantages of both
machining processes. Primarily, these are the productivity of hobbing and
the flexibility of gear shaping. Especially when machining internal gears
compared to gear shaping, the gear skiving process scores with significantly
higher productivity. Machining times for gear skiving are around 30% to 50%
compared to the gear shaping process. In contrast to gear shaping, however,
due to the inclined position of the tool in relation to the workpiece (cross-
axis angle), gear skiving requires a machining path that is slightly larger
than the width of the gearing to be produced. These additional paths are
called approach and overrun distance. They increase as the cross-axis angle
increases. Due to these necessary approach and overrun distances, gear ski-
ving has few restrictions compared to gear shaping with very narrow internal
gears and interfering contours. For the majority of applications that were pre-
viously reserved for gear shaping, gear skiving is a much more productive and
economical machining method.
