Global Auto Market Trend

The global auto market is growing in both the quantitative and the

qualitative aspects.

In the quantitative perspective, emerging auto markets such as BRIC

are accelerating the growth of the global auto market. Statistics

report that the world motor vehicle production would reach 88

million vehicles a year by 2014, and the vehicle ownership to be 1 car

per 7 persons by 2020.

The quantitative aspect has much to do with the evolvement of auto

production trends.

As the auto makers develop strategies according to the globalization

trend, eco-friendly, energy saving, safety, and telematic of vehicles

has become major factors leading to the change and development of

auto production technology.

As a result of the ongoing auto market growth and evolvement, new

machining technologies are required to meet the production trends.

The key features in demand for new machining technologies are

higher speed, efficiency, and precision.

And at the forefront of the new production technology is Cubic

Boron Nitride.

Introduction to CBN

As the second hardest material after diamond, Cubic Boron Nitride

(CBN) is widely accepted as the most efficient abrasive material for

grinding ferrous materials.

Superior hardness, abrasion resistance, and thermal resistance of

CBN have been proven to deliver far longer life and quality for

grinding tools than conventional materials such as silicon carbide

and aluminum oxide.

Shape, size, and hardness are the key elements in determining the

quality of CBN, thus it is critical that a CBN manufacturer has the

controlling capacity.

Introduction to IBN

With over 25 years of accumulated synthetic diamond manufacturing

experience, ILJIN Diamond produces IBN, which is CBN with differenti-

ating qualities from other CBN products.

ILJIN Diamond attests its product quality only with result and perfor-

mance.

Our constant feedbacks from customers who apply IBN in the grinding

works include: consistent grinding result, prolonged tool life, signifi-

cantly less tool wear or damage, and growth in productivity.

In addition, the common characteristics across IBN grades are high

machining efficiency and precision.

ILJIN provides varieties of CBN products with shapes, sizes, and

properties that specifically comply with customers’ requirements.

The Ultimate Material for Auto Component MachiningIBN for Cam/Crankshaft Grinding

Properties of IBN-950

These properties make IBN-950 an ideal selection for crankshaft

or camshaft application.

Particular properties that make IBN-950 ideal for camshaft or

crank grinding are its sharp cutting edge and operation efficiency.

In addition, IBN-950 is a popular choice for grinding many other

automobile parts such as CV joint, die, and gear.

IBN

IBN-950, IBN-750, IBN-500 are in dark brown color and have angular particle

shape, which offer superb grinding performance with less grinding power. Its

property of continuous regeneration of sharp edges upon fracturing makes

IBN-950 and IBN-750 especially suitable for camshaft/ crankshaft grinding, and

many other applications.

IBN-300 and IBN-200 have low impact resistance and irregular shape, which make

tools less likely to have cutting overload. IBN-300 and IBN-200 are suitable for

precision grinding. Their major application is grinding precision parts such as

bearings and gears.

IBN-30 has a rather blocky shape, and it is applied to a wide range of metal bond

tools. Because of its crystal shape, IBN-30 is especially recommended for applica-

tions in which surface roughness is important.

IBN-5000, IBN-3500, and IBN-3000 are characterized by sustainable toughness

under very high impact load and heat. The crystals can be manufactured to have

blocky shape similar to IBN-5000, or sharp edge similar to IBN- 3000 depending on

the application. IBN-5000, IBN-3500, and IBN-3000 are widely used in vitrified or

metal-bonded tools. These products especially render exceptional performances

when applied to electroplated tools grinding very hard aerospace materials, and

applications which have to bear substantial cutting load. By harnessing its superior

impact resistance, IBN-5000, IBN-3500, and IBN-3000 can present longer tool life

and excellent machining results for materials from hardened steel, and alloy steel

to cobalt based nickel superalloy.

IBN-6000 is a polycrystalline product with properties of high toughness, sharp

facet, and micro chipping, which make IBN-6000 a fabulous choice for application

which requires high removal rate. It is widely used in metal-bonded and

electroplated tools for honing and grinding.

Application

IBN-40 and IBN-20 are black-colored CBN with medium toughness, and they

consist of quasi-regular mono crystals. They are the most general choice of products

for wide range of applications including vitrified wheels and electroplated tools.

There are hundreds of materials that require grinding works: superalloys, bearings,

gears, hardened steels, and many other materials for aerospace. IBN from ILJIN

Diamond is a very effective and efficient material for grinding applications.

IBN products are classified by size and toughness. By referring to the table, custom-

ers can choose a pertinent CBN grade with suitable toughness and fracture

properties to improve surface finishing, prolong the tool life, and extend the

dressing intervals.

The distinctive fracturing property of each product renders longer tool life and

lower grinding power consumption, thereby enabling life extension and cost saving

for shape machining.

Comparison Chart ▶

As automotive components have been developed to be more hardened and light

weighted, the spectrum of CBN application has expanded accordingly.

The properties of CBN considerably contributed to better end products, less

thermal wear, outstanding surface finishing, and enhanced consistency of

quality results. For the last 25 years, IBN of ILJIN Diamond has been evolving

along with automotive machining tools, providing solutions for precision

machining.

IBN-200, which has low impact resistance and widely used for electroplated

wheels, along with IBN-500 are applied to bearing application which is largely

used across many manufacturing industries including automotive.

Also, on account of the sharp crystal shape and superior machining efficiency,

IBN-950 and IBN-750 are extensively used for camshaft and crankshaft which are

pivotal components for automotive. IBN-950 is additionally applied to numerous

other automotive machining such as CV joint, Die, and Gear machining.

For machining engine valve, IBN-5000 and IBN-500 are recommended due to

their high thermal stability at elevated temperature.

Characterized by the properties of sharp edge, micro chipping, and fast removal

rate, IBN-6000 is highly recommended for machining cylinder block, together

with IBN-5000.
