Introduction
Asahi Diamond Industrial is one of the world leaders in Diamond tooling supporting the Engineering,
Construction and Mining sectors with high quality Diamond products that are reliable and cost effective.
Technology advances are so rapid that one year old technology may be considered redundant. To keep
pace with these technological advances Asahi Diamond continually develops and modifies high
precision, highly efficient tools, while promoting application development.
Used in a wide range of applications, Diamond tools are used within the mining sector for drilling and
geotechnical operations where high quality and reliability is required.
They play an integral role in preventing excessive noise and protecting the environment. They are also
used for dismantling buildings and bridges, seismic strengthening, upgrading infrastructure, and
processing of various types of stone.
Asahi Diamond Industrial through a stable supply of raw materials and through a constant development
process can guarantee stable, high quality products across the range.
Our Story
In 1947 Triefus Company Ltd. became a public company and its shares were quoted on the London
Stock Exchange. At this time there became an increasing awareness of the importance of Diamond tools
of all types in the modern industrial world. An engineer was appointed to the staff and following a small
investment Triefus and Company Limited commenced manufacturing single point Diamond dressers.
By 1949 a small manufacturing company was established which made its first take-over in 1952.
Expansion became rapid and profits grew. Also in 1949 a survey of Diamond tool and drilling potential
was undertaken in Australia. Sales of rough Diamond commenced in 1950 and a small manufacturing
plant set up the following year. Similar plants were established in other countries including France and
India.
World demand for industrial Diamond products increased dramatically and the close links already
established with industrial Diamond merchants and product manufacturers resulted in rapid growth for
the Triefus group. A particularly close association developed between the Triefus UK manufacturing
company and the Asahi Diamond Industrial Co. Limited which had been established in Tokyo in 1937.
This close association was later expanded to include cross shareholdings and eventually led to Asahi
taking control of the Triefus Group in 1990.
Asahi Today
The Asahi group is one of the world’s largest manufacturers of industrial Diamond products with an
enviable reputation for service and expertise.
Asahi Australia were manufacturing and marketing industrial Diamond products right up until 2002 at the
principal office and factory located in Mona Vale NSW, a northern beaches suburb of Sydney. Sales
Offices are still maintained at these premises with products being sourced from our Group Companies in
Japan, France, South Korea, Taiwan and Indonesia, with our products and services being used in
various Diamond application areas for:
- Mining and Exploration
- Precision Engineering
- Construction Projects
2
All of our mining products are manufactured in our state of the art Jakarta factory, where our first factory
was built in 1996 predominantly to supply and service the South-East Asian market.
Our Australian factory ceased production in 2002 and all our equipment and manufacturing expertise
was transferred in total to our Jakarta plant at this time, and now produces our extensive range of mining
and exploration products that we supply globally. We are now in our third built factory in Jakarta having
grown out of our previous two, and have recently been quality accredited with ISO9001 Certification.

Diamond and CBN Wheels
Grinding is an indispensible step of the manufacturing process.
Asahi Diamond manufactures a comprehensive range of “super-abrasive wheels” using the highest
quality Diamond and CBN (Cubic Boron Nitride) particles.
Super-abrasive wheels display the following excellent characteristics unfound in conventional abrasives:
 Faster cutting speeds
 Higher heat and wear resistance
 Improved accuracy and surface finish
 Minimal dust creation
These characteristics provide improved safety, increased operation efficiency and lower tool costs.

Diamond vs. CBN
Diamond is the hardest material known to man and has great abrasion resistance.
These properties make Diamond wheels the preferred choice of abrasive when grinding materials such
as sintered carbide, glass, ceramics and other hard non-ferrous materials.
CBN is a more suitable abrasive than Diamond when grinding ferrous materials. It has a heat resistance
of 1200˚C, while Diamond begins to oxidize at 600˚C.
Unlike Diamond, CBN does not chemically react in a negative manner to iron. Therefore CBN wheels
are
used when grinding steel alloys such as carbon tool steel, HSS, die steel and other hard alloys.

Resin Bond Wheels
Resin bond is usually made with a heat-cured resin mostly composed of phenolic resin. They provide
excellent grinding ability, surface finish and minimal chipping.
Resin bond super abrasive wheels are widely applied to difficult to machine materials such as cemented
carbide, ceramics, glass, and silicon as well as ferrous materials such as tool steel, HSS, die steel and
other hard metals.
Characteristics of resin bond wheels
 Resin bond usually has added organic and inorganic materials and metal filler. These materials
are added to the phenolic resin in order to control wear resistance, heat resistance, grit retention
and lubrication.
 Resin bond wheels are low in Young’s modulus (elastic modulus). As a result excellent
characteristics are achieved in processing efficiency, free cutting ability, surface finish and
minimization of chipping.
 In comparison to metal bond wheels, resin bond wheels have weaker adhesion between the grit
and the bond. This results in a much better cutting ability when processing hard to grind
materials such as cermets, ceramics etc.
 The Diamond and CBN abrasives used in resin bond wheels are irregular shaped and easy to
micro fracture. This allows new cutting edges to be constantly created while grinding.
 Resin bond wheels are typically used for wet grinding, but they can be used for dry grinding by
adding some filler during the manufacturing process. The use of this filler reduces heat
generated in the grinding process and improves cutting ability.
Applications of Resin Bond Diamond wheels
 Resin bond Diamond wheels are most commonly used for precision grinding of cemented
carbide, cermets and ceramics.
 Because of the bond elasticity they are used for finish grinding of silicon, glass, ceramic made
electrical parts etc. where excellent surface finishes are required.
Application of Resin Bond CBN wheels
 Resin bond CBN wheels are suitable for grinding ferrous metals such as cast iron, HSS and
sintered iron.
 CBN is superior in precision grinding applications when compared to conventional abrasives.
They wear less than conventional abrasives and are suitable for processing hard to machine
materials due to the hardness of the CBN particles. Higher thermal conductivity also allows for
less heat to be absorbed by the work piece during the grinding process.
6
Metal Bond Wheels
Metal bond is a binding material made of metallic powders comprising copper, tin, iron, cobalt etc. Metal
Bond Wheels have excellent grit retention and wear resistance compared to other bond types.
Characteristics of Metal Bond Wheels
Divided into three major types:
1. Bronze type – superior in grinding ability
2. Cobalt type – superior in wheel life
3. Steel type – stands between bronze and cobalt types regarding grinding capabilities
 Excellent grit retention and wear resistance in comparison to resin bond wheels. Long tool life is
achieved when processing difficult to machine materials such as glass, ceramics, semi-conductor
electron materials etc.
 Due to its electric conductivity it can be used for electrolytic grinding and electrical discharge
grinding (EDM).
Applications of Diamond Metal Bond Wheels
 With excellent grit retention and wear resistance Diamond metal bond wheels are used for
rough/semi finishing difficult to machine materials such as: glass ceramics, ferrite, fireproof
materials, stone etc. Exceptional results are achieved during chamfering processes.
 Widely used for form/profile grinding in which Diamond wheels are required to keep profile.
Applications of CBN Metal Bond Wheels
 Excellent wear resistance of the bond gives excellent efficiency in rough grinding of unhardened
steel materials.
 Highly recommended for grooving of hardened steel and grinding which requires high efficiency
and accuracy.
7
Electroplated Wheels
Electroplated wheels bring stable performance in grinding accuracy, grinding ability and wheel life. They
have an excellent reputation in a variety of applications.
Characteristics of Electroplated Wheels
 Constant in grinding ability and can be used for many materials because of the high amount of
abrasive material protruding from the bond.
 Capable of holding form at low cost, therefore suitable for form wheels.
 Best suited to produce small volume production in wide ranges. Electroplated wheels are
inexpensive and wheel life is shorter than other bonds because they are typically a single layer of
abrasive material.
 The consumed abrasive can be stripped and re-plated using the existing core (provided it is not
damaged).

Grinding Wheel Care and
Practical Application
Please consider the following information when using Diamond and CBN Wheels.
Doing so will provide an environment for the best grinding performance
and service life of your Asahi wheel.
43
Wheel Mounting
After removing the previous wheel the mounting arbor or flange should be cleaned and checked to
ensure that there are no burrs or score marks on any of the wheel bearing surfaces.
NOTE: Paper washers should never be used as packing
materials.
Set the balancing weights on the arbor or flange to such a position that they are equidistant from each
other.
Locate the wheel onto the arbor or flange and tighten the locknut sufficiently, allowing the wheel to move
only when lightly tapped.
Using a dial indicator gauge and moving the wheel by hand, the periphery is gently tapped with a soft
mallet or wooden block until minimum run-out is achieved. It should be possible to tap the wheel to
within 0.01mm of running true.
Extreme care should be taken when tapping ceramic bonded wheels as they are by nature non resilient
and are likely to fracture when subjected to physical shock.
Tighten the locknut or bolts and clock the wheel again to check that it has not moved during tightening.
44
Truing and Dressing
Truing Diamond Wheels
The wheel is trued using a brake truing device as follows:
 The truing device is positioned so that the axis of its spindle is parallel to that of the machine bed
or chuck, and directly beneath the Diamond wheel to be trued. (Fig 1).
 The device is then passed across the wheel face using the cross feed. This is repeated and the
Diamond wheel bought down onto the truing wheel in increments of 0.01mm applied at each side
of the wheel. (Fig 2).
 This process ensures that the Diamond wheel will be correctly trued with minimum wastage of
time and Diamond.
 Once running perfectly true, wheels should then be balanced on its arbor or flanges either
statically or dynamically.
 It is important to note that it is far more economical to true with a proper truing device than to let
the wheel run-in.
 If the measured run-out of the wheel is 0.01mm it is only necessary to remove that amount to
achieve running truth. However, to let the wheel run-in it may remove 10x that amount and still
not be running true or in balance.
 If the wheel is resin bonded it is now ready for work. Ceramic and metal bonded wheels further
require dressing to enable the wheel to operate at maximum efficiency.
45
Truing CBN Wheels
Resin bonded CBN Wheels are trued using a Diamond dresser (PBP-17 type, S/C 1007) as follows:
 The Dresser is held in a conventional holder and must be set on the centre line of the wheel.
 Approx 0.015mm deep light cuts are taken across the face, until face is trued right across.
 If the face of the trued wheel is glazed up and won’t grind efficiently you must dress the wheel in
order to expose the CBN particles.
 Metal bonded Wheels must be trued using a brake truing device with a silicon carbide wheel.
Follow the same process as described for truing Diamond Wheels.
Dressing Diamond and CBN Wheels
Use a grade A80-GV aluminum oxide stick (S/C 9652).
For best practice, the stick should be held mechanically and fed into the wheel. Care should be taken
that the dressing action is evenly applied over the full face of the wheel.
If the dressing stick is held by hand it will follow the contours of the wheel. As there are invariably
differences in bond hardness round the periphery of the wheel, the stick will tend to remove material
preferentially promoting run-out. Even a balanced wheel may run out of true if the dressing stick is held
by hand.
The wheel is now ready for grinding.
In some cases dressing may be necessary to remove build up of braze or steel from the surface of
the wheel during its life.
46
Storage
Diamond and CBN Wheels should be carefully stored in their own box or kept on their own arbor.
Machine
Machines should be rigid, well maintained and free of vibration.
Particular attention should be given to the running truth of the spindle and the condition of the spindle
bearings.
Cutting Fluids
Diamond and CBN Wheels perform best when wet. Coolant measurably increases tool life, surface finish
and grinding ability.
Pure oil is the best coolant; however, if not available water soluble oil can also be used.
Supplying coolant directly to the exact grinding point is most effective.
Wheels which are to be used without coolant require a bond composition specific for dry grinding. This
bond can be recommended by Asahi technical engineering staff.
Speeds
Peripheral grinding speeds vary according to the working condition - Speeds greatly influence
performance.
It is impossible to provide peripheral speeds for every conceivable circumstance, however, Asahi
recommends the following general guidelines:
Bond

CBN

Resin 17 – 30 m/sec 12 – 17 m/sec 25 – 40 m/sec 13 – 25 m/sec
