REAMING WITH A NEW RHYTHM
K. Ravi Kumar
General Manager- Asia Pacific
04 KOMET INDIA
Traditionally, precision holes are machined
through several processes, such as fine
boring, grinding, honing, polishing, super
finishing and, reaming. Among all these
processes, reaming plays a vital role, in
reaching the required tolerance, surface
quality and other geometrical accuracies.
The conventional reaming process is a slow process,
as opposed to the machining time, which is quite
high. So, generally, for finishing operations, the
most opted process is that of grinding or honing.
Manufacturing technology
evolved over the times and the
introduction of CNC Machine
tools has enabled high spindle
speeds, linear speeds and
flexibility. Thus, demanding a
high performance in cutting
tools.
Reaming, being a multi- point
cutting tool, operates at a high
cutting speed and feed rate,
bringing machining time and
cost, considerably lower than other processes.
WHAT IS HIGH SPEED REAMING?
Technology has helped us move ahead of
conventional reaming, to high speed reaming, for
better results. High speed cutting drastically reduces
cycle time, improves surface finish, and delivers
better cost per component, leading to better
productivity. As is visible from the above graph,
conventional reaming operates at a low speed and
feed rate, whereas high speed reaming performs a
very high speed and feed rate.
THE KNOWHOW
Illustrated below, is the Cutting Edge Reamer.
The whole High Speed Reaming Technology shows
us how these details in micron levels are prepared
and maintained consistently, for a consistent
performance of a Reaming Tool.

THE MUSIC PLAYS AT THE CUTTING EDGE
It's not just the cutting edge, alone, that brings a
high performance while reaming. The vital role is, to
choose the right cutting material, and the newest
coatings. The cutting materials are sub-micron
carbide substrate, which are suitable for all kinds of
work piece materials, to be machined together, with
TIN and DGB-N coatings. The other harder substrate
is DST which offers a higher wear and tear resistance,
to ream in all kinds of steel, stainless steel and,
Nodular iron. DST, being
the hardest substrate,
automatically offers to
operate, at a cutting
speed of VC=100 to 300
meters/minute, with a
guaranteed longer tool
life. With the additional
DBG-N coating on DST
cutting material, the
performance of the
reamer can further be
enhanced, to extend the
tool life. DST, being the harder substrate than
carbide, is also brittle in nature and therefore, is not
recommended for reaming, with interrupted
conditions.
The new high-tech coatings, for the reaming heads
®
of the DIHART Reamax TS tooling system, enables
the KOMET group, to accommodate the increasing
diversity of materials, and to offer more individual
tool designs, for a quicker machining process.
Coatings, on cutting edges, make a fine, yet crucial
difference in the rhythm of reaming. In addition to
the high-performance of DBG-N, which has so far
proved very successful, the KOMET group has now
developed an alternate product, in the shape of its
new DBF coating, which is suitable for Machining
Cast Iron, Modular Cast Iron and Vermicular Cast
Iron. This provides the user with more options, to
respond to the increasing variety of material quality,
to optimize cutting values, through individual
tool designs. The new BDF coating is particularly
aberration resistant, and is suitable for high
cutting speeds.
Power in sound, i.e. quicker machining, is also
the aim of the new DBC coating. It is ideal for
aluminum wrought alloys, and aluminum cast
alloys with a low silicon content and copper
alloys. As a diamond like carbon coating, it
enables high cutting speeds.

Aluminum is increasingly becoming a component in
manufacturing industries, such as Automotive parts,
Aerospace etc. Automotive parts, like Gear Box
housing, Cylinder heads, Transmissions, Steering
housings, Pump housings etc., are of a high volume
production and need high performance tools to
ensure consistent quality levels and process
capability. The picture below represents aluminum
machining, with various cutting materials. It is clearly
evident that most of the cutting materials are not
stable in terms of performance, while the PCD is the
best cutting material we can rely on for the high
process consistency of machining bores. The main
reason for the other cutting materials not being able
to perform, is that aluminum, has the affinity for a
built-up edge with carbide, whereas PCD does not
have any affinity for a built-up edge. This gives the
PCD a longer consistency in performance and
enables endless tool life.
The Monobloc tools are single piece designs, mainly
used for a smaller diameter, from dia.1.4 to 18mm,
Some examples of the automotive parts
Standard PCD reamer Special PCD reamer
while the modular designs are from dia.18 and above
until 300 mm. The Expandable Reaming Tools range
from the smallest diameter, dia 5.6mm to dia 300mm.
APPLICATION AREAS OF PCD TOOLS
The DIHART brand of KOMET Group, pioneered in
introducing (Poly Crystal Diamond), cutting material
in the market, as the hardest substrate for machining
bores, way back in the 90's. The major application
areas are, Machining Aluminum and non-ferrous
materials, in the automotive and aerospace industry.
Today, the trend is that, most of the automotive
industry, especially the engines and transmission
parts of a car is made out of Aluminum with a Silicon
content of 8% to 13%. The automotive part
production, being of high volume, means that there
is a demand of high process capability, without any
quality deviations. PCD Reaming Technology offers
tremendous benefits, holding the high quality levels
of the parts with unbeatable tool life, in the range of
2000 to 5000 metres of cutting length, thus ensuring
the highest process capability. Certain parts, worth a
mention, in the automotive industry, are
Transmission Housing, Gear Box Housing,
Cylinder Head, Cylinder Block, Steering
Housing, Master Cylinder, Wheel Cylinder,
Throttle Housing, Pump Housing and so on.
It is also noteworthy that the Two Wheeler
Industry, has also benefitted from the PCD
technology, in machine parts to name a few,
like Cylinder Head, crank case LH and RH,
Clutch Lever Housing, Cover Magneto etc. The
traditional two wheeler production had to use
the special purpose multi-spindle machines,
thus making it inflexible with low outputs,
and creating many quality problems and
rejections. The PCD Reaming Technology has
been very successful, even on the special purpose
machines, to bring down the rejection levels to
ZERO. This has resulted in changing the process to
utilize the best advantage of PCD tools and
introduction of the latest CNC machining centre, in
place of using age old special machines. The
combination of PCD Reaming tools and the CNC
machines brought tremendous benefits, in terms of
highest quality levels, and increase in productivity to
over 200%, thus reducing the investments on
machinery and increasing overall cost benefits.

paramount importance,
for high precision and

Reaming Tools.
EXPANDABLE REAMERS
Expandable Reaming Tools offer a huge benefit, in
compensating tool wear and tear, in order to increase
the tool life without compromising on the quality. It
also enables to ream holes up to IT4 quality bores. The
picture below illustrates the expandable technology
of a reamer, which is quite simple to handle by the
production team, without setting any equipment.
CONDITIONS FOR HIGH SPEED IN NEW RYTHM OF
REAMING
Precision bore machining, with High
Speed Reaming Technology, requires
certain machining conditions to be
fulfilled, to enable the use of
optimum cutting data, that achieve
excellent surface quality, circularity
and cylindricity even at the end of its
tool life. The basics are to ensure the
right alignment from the machine
spindle to the work piece and the
true running of the reamer, which
means, that the run out on the
cutting edge must be less than 0.003.
With the Dihart Compensation
Adaptor System it is even possible to eliminate any
misalignment of the spindle to ensure the true
running of the reamer.
THE COOLANT FACTOR
The inner coolant supply for High Speed Reaming is a
very important factor as it lubricates the cutting edge
along with the circular land and chip face to increase
the tool life. It also reduces heat generation and
keeps the cutting edge cool and assists better chip

evacuation while machining, to increase wear and
tear resistance. It also helps to avoid or delay the
process of built up edge. The coolant
recommendations are to use water based soluble oils
with up to 6% to 8% mixture. The coolant pressure
should be a minimum 10 bar.
CONCLUSION
Spindle
Tool
Workpeice
Dihart, the reaming brand of KOMET GROUP, has
been a pioneer in Multi-Blade Reaming Technology
and strives to introduce more innovative tool
concepts like Reaming, with indexable inserts, along
with new coating technologies and special chip
breaking geometries for machining soft materials.
These innovations will benefit modern machines
that are used in industries like automotive, power,
generation, aerospace and machine builders to
keep upbeat with the new rhythms of high speed
reaming.

INDEXABLE DRILLS
- A Boon to Productivity
Drilling is the most productive method of hole
making and the indexable insert drills started a
revolution in the drilling process. KOMET GROUP
the pioneers in indexable drilling, has developed
many of the revolutionary tools in this category.
Higher productivity, combined with excellent hole
quality are the major benefits of KOMET KUB
(Komet Universal Bohrer) family drills. Reduction in
manufacturing costs and easy handling are the
central theme of the indexable drill solutions. Throw
away inserts make these tools very user friendly and
eliminate the tedious regrinding and recoating
process. The small drilling inserts, also offer best
adaptability to the latest developments, in the
cutting tool geometry and revolutionary coating
process.
The major challenge in solid drilling is the effective
removal of the chip from the machined bore. An
effective swarf removal can be obtained by the
optimization of the flute design, balancing and
cutting forces, appropriate chip breaker geometry
and a suitable surface treated drill body.
For more than 30 years, the KOMET KUB solid drill
family has been developing a leading tool concept,
through the use of high performance hard metals
with special treatment combined with excellent tool
geometry, with latest generation insert coating.
Thus, KUB Drills offer an unmatched performance in
solid drilling.

KUB TRIGON for Low Power
Machines & Close Tolerance Holes
As early as 1977, KOMET
introduced the world's first
indexable insert drill bit,
without a HSS centering tip,
thereby, laying the foundation
for a triumphant process of the
KOMET KUB FAMILY. The close
bore tolerance up to H8 and an
extremely good surface finish allow
machining to finished dimensions,
without a separate machining operation.
KUB Trigon, starting from a diameter of 14
mm, up to 54 mm, goes to a drilling depth of
0
4xD. KUB Trigon, having an 84 edge angle and
having a variable radial fitting angle, enables to
balance the cutting force and is the best answer to a
low spindle power machine tool for best
outputs.
KUB Duon for flexibility in diameter
KOMET Kub Duon, is based on the
principle of exchangeable cutting
elements in double edged tools. The
double insert screw-on drill design
offers double the feed rate and a
high cutting speed. The variety of
precision ground inserts with an
increment of 0.1 mm in diameter, is
available in various diameter
ranges and can be accommodated
to the same drill body, which
makes it very flexible in drilling
depths up to 5D.

THE INTELLIGENT MANUFACTURER
The newspaper sitting on my desk
read “HARD DAYS AHEAD”.
I glanced through a couple of
more headings, but sentiments
were common across Euro-Zone,
US, Asia and the rest of the world.
The combination of domestic
issues and worsening global
prospects has put even the Dragon and the Tiger on
to the radar.
Is the ghost of 2008 back to haunt? If it is, the
question now is, not how to weather the storm, but
how to stimulate growth.
As the World Economy faces a grim situation, akin to
2008 this question looms across board rooms.
It is time, that we revisit some of the hard lessons
learned through 2008 but conveniently forgotten by
2011.
Most of us know the CONTROL LESSON, the days we
started controlling the cost and inventory process,
albeit with everything and anything.
But is control the mantra for an intelligent
manufacturer who wants to stimulate growth during
hard times?

Predictably, the answer is, no. We need to optimize,
not control.
We need to keep the ball rolling, by developing
intelligent ways of managing inventory, not only
keeping stock of essential items at our end, but at the
same time, maintain stock at the suppliers end, and
stretch deliveries over a period of time.
Our day to day activities spare us little time to test the
tenacity of our process. It is the key to optimize the
existing process, with a clear focus on reducing the
lead times.
Effective utilization of man, machine and other
resources, to clear the existing bottlenecks, is
primary.
But, most importantly, we should connect with our
suppliers and explore ways to improve the quality of
products and reduce cycle times by trying out latest
technological developments and proven solutions.
Another vital step is to adopt world class
manufacturing practices and implement them.
Integrating the latest IT infrastructure to existing
systems is equally crucial. These practices will help us
compete globally and make our environment the
best place to work in.
“When the going gets tough, the tough get going”,
goes an old English proverb. It is essential to take the
lead in order to succeed in hard times. All others
follow to failure.

TIPS AND TRICKS
Avoiding Broken Drills - ‘know-how’
Broken drills in metal-machining
production usually have fatal
consequences and broken tool
monitoring systems only kick in
when the tool is already broken. To
prevent this happening in the first
place, employees need to be able
to recognize latent problem areas
and initiate suitable measures.
Broken drills are not usually a
sudden occurrence.
Problematic areas where broken
drills are most likely to occur
include extreme machining
processes with interrupted cuts.
Unstable components such as
welding structures or stack plate
machining can also present
problems. Long chipping materials

- Component stability
Choosing The Correct Drilling Method
as well as abrasive materials and high-strength
materials require special attention too. Last but not
least, problems can also occur on the machine side if
the center height is no longer correct in a lathe for
example, or the revolver disc can no longer stay in
position under the feed force.
The possibilities of avoiding broken drills are a
combination of several inter-related measures that
trained machine operators can perform. One of the
main conditions, however, is that he is in a position to
recognize when a drill could break and the reasons
for this so that they can be eliminated or minimized.
Some experienced hands might quite literally be able
to sense changes in the process or feel them through
unusual vibrations, but a periodic visual inspection of
the drills is more reliable.
This is where employee training becomes a success
factor.

Journey with KOMET
As Bestall Engineering is into the machining of large
components, successful machining of bigger
diameter holes was really a challenge. The existing
drills were failure as the chip breaking and chip
removal was very difficult with those tools.
Bestall tried an alternative method of hole milling
with helical interpolation methods. Though the
machining was possible with this method, the time
taken for this operation was too high.
That was the time KOMET team entered the scene
with its proven drilling solution.
With the well known
KUB technology it was
really a cake walk for
the KOMET team to
solve the problems at
Bestall.

KOMET RHOBEST
The KOMET GROUP took over rhoBeSt
GmbH, and is expanding its coating
expertise. Innsbruck-based KOMET
RHOBEST is a research-oriented company
whose core competence is in the field of
nano diamond coating. With the
acquisition, the KOMET GROUP is
extending its know-how in the coating
sector and will be launching high-quality
“customized“coatings for aviation and
aerospace applications, mould
construction and the energy sector onto
the market in future. For the first time, the
method patented by rhoBeSt allows ultra-
fine, top-quality and high-purity diamond
layers to be applied even to large and
complex-shaped surfaces. The KOMET
GROUP is using this process for the
diamond coating of tools which are
particularly suitable for machining fibre-
reinforced plastics and aluminium alloys.
Coatings with Nano-crystalline Diamond
KOMET RHOBEST uses its own in-house developed process which allows a large range of base materials to be
given a high-quality coating for the first time. At the heart of the process is the highly efficient preparation of
atomic hydrogen from the gas phase of methane and hydrogen, which creates nanocrystalline diamonds on the
surface of the base material. No matter the base material used, its surface is given the characteristics of a
diamond. The special process allows the precise setting of crystallite size, and thus surface roughness. The
preparation of so-called ultra-nano-crystalline diamond layers results in very smooth surfaces and extremely
sharp or hard cutting edges due to the size of the nano diamonds (< 10 nm). The tiny size of the nano diamonds
means that the relation between surface and volume significantly increases and with it the number of surface
atoms. As a result, there is a significant improvement in both the adhesion and stability of the layer, as well as its
mechanical properties. The RHOBEST process allows the precise setting of crystallite size, and thus surface
roughness.
