Normally PCD Cutting Tools can be used various industry, such as Automotive parts(pistons,Wheel Hub, Engine block), Airplane(CFRP, PMMW) and other non-ferrous metal materials. And this article show you the main application field of pcd cutting tools.And we can offer most pcd cutting tools. we have different pcd grade CDW10, CDW20 and CDW30 specific for different materials.

（1）Cutting Speed Vc
PCD Cutting Tools can be used for high cutting speed, it can
arrive 1000m/min when turning Aluminum alloy component,
and the speed can reach 3000m/min when milling.
（2）Feed Rate Fr
We can choose the reasonable feed rate depending on different
condition, if feed is large, it will affect the surface roughness, if
small, it will lead to high cutting temperature
（3）Cutting Depth ap
We can choose the machining technology, if the cutting depth
too large, it will affect the tool life.

Application Range of PCD Cutting Tools
（1）Machining Non-ferrous metal
（2）Machining Non-metal materials
When machining copper, zinc, aluminum and other non-ferrous metals and their alloys, the
material easily adheres to insert. Due to the low friction coefficient of PCD and the small affinity
with non-ferrous metals, PCD tool can effectively prevent the metal from binding with the tool,
and the blade deformation and can obtain good surface quality.
When Processing glass fiber reinforced plastic, silicon packing materials, hard carbon fiber /
epoxy composite materials, carbide insert will wear serious tool, difficult to process, and PCD
tool have high hardness, wear resistance, high processing efficiency.

PCD Cutting Tools for Automotive Parts
PCD Cutting tools are widely used in automotive engineering, engine skirts, pin holes and
cylinder blocks and other components. Due to the high Si content of these components
some exceeds 10%, so the hardness and service life of the tool have high requirements,
Normally we use pcd cutting tools make sure the high processing efficiency and the
surface quality.

PCD Cutting Tools for Automotive parts-Aluminum pistons
In order to improve the performance of the engine, the piston materials
usually use Silicion Aluminum materials. And the high content silicion
have high hardness and wear resistance, and also are difficult to
machine. And the cutting tools machine the soft Aluminum and hard Si
particle, the characteristics of the pcd tools can meet all the
requirements.

PCD Cutting Tools for Aluminum Wheel Hub
Aluminum alloy wheels stand out in the automotive industry with its advantages of light weight, fast
cooling, good shock absorbing performance, long service life, safety and reliability, beautiful appearance,
colorful patterns, precise dimensions, good balance and easy manufacture. And the following have shown
some of the pcd tools for machining wheel hub.

11. Let the world no longer have difficult to machine materials!
PCD Cutting Tools for Automotive Parts-Engine Block
In recent years, Aluminum engine block begin to become light weight, small size, high precision,ect. Becasue of
high hardness, low thermal expansion coefficient and other characteristics, pcd inserts have been the most
suitable cutting tool materials for machining Aluminum alloy component. Comparing with ceramic cutters or
carbide insert, the cutting speed can improve several times,and the tool life will be better.
The following is one application case:
Machining Mateirals: AlSi9Cu3（Fe）
Cutting Condition: Interrupt Cut
Cutting Depth:0.5~0.7mm
Machining Length:735mm
Tool Life:30000pieces

PCD Cutting Tools for Airplane
As we all know that the materials that can be used airplane must have special advantages. With long time
experience on the materials, normally we usually use Ti alloy, Aluminum alloy and composite(CFRP,PMMA)
as the main materials, normally cutting tools (carbide inserts, ceramic cutters) can't meet the size and the
surface quality requiremetnts. PCD Cutting Tools have been aproved that can be used for most mateirals in
Ariplane. The following is some machining part of the airplane:

PCD Cutting Tools for 3C Industry
With consumers' increasing demand for lightness, thinness, shortness, smallness and fashion trendiness,
"3C" products based on high-tech digital, intelligent and networked technologies (Computer,
Communication, ConsumerElectronics electronics) appear one after another, they have become a very rich
variety. In the "3C" product shell applications, magnesium alloy has gradually replaced ABS, PC and other
materials. So The cutting tools begin to replaced by the PCD Cutting Tools which is the most suitable
cutting tools for machining non-ferrous metal and other alloy.
