Brief Introduction of Cutting Tools Material in Modern Times
Part 1 Cutting Tools Materials Performance
requirement
Tool material performance requirements are
mainly include strength, hardness, heat resistance, thermal conductivity and
economy five areas.
First, as the tool material, high strength
and wear resistance are necessary. The Cutting Tool should cut the workpiece to
form the special shape. Actually, the cutting tools cut the materials depending
on the Friction between the cutting tools and the workpiece. So wear resistance
is also a character of cutting tools. Generally, hardness higher, better wear
resistance. So the cutting tools need high hardness and excellent wear
resistance.
Second, the cutting tool material need obey
the vibration and shock between the cutting tools and the workpiece. So the
cutting tools need high strength and good toughness.
Thirdly, the tool material needs to have
good heat resistance and thermal conductivity, in which heat resistance is an
important indicator of the quality of the tool material. As mentioned above,
the cutting of the tool actually depends on the high-speed friction between the
cutting tools and the workpiece. Friction heat, also known as cutting heat, caused by the
friction between the tool and the workpiece. So how to keep the excellent
performance in high temperature is very important.
Forth, the cutting tools need excellent
thermal conductivity, then the cutting tools can quickly pass the cutting heat,
and reduce the heat amount and keep the tools good performance in the process.
Finally, the economy of the cutting tools.
There are so many kinds of cutting tools materials. And the manufacturers also
insist researching new cbn inserts materials, also the tools price will be
different. So the customers should choose the right and suitable tools
depending on their own conditions.
Part 2 The Classification of tool materials
Common Cutting Tools Materials include high
speed steel, carbide insert, coating insert, Ceramic, Diamond and Cubic Boron
Nitride.
(1)
High-speed steel is generally
used as a tool for forming tooling and hole cutting tools, but it is often used for low speed cutting because of
its performance. However HSS cutting tools with high performance also are
widely used after improvement.
(2)
The performance of the carbide
insert will be better than HSS Tools, carbide insert are also used common
process. And HSS tools also begin to be used in complex process with the
improvement of the performance.
(3)
Coating Inserts are the tools
of adding special coating on the HSS tools and Carbide insert, in order to
improve their performance.
(4)
Diamond Tools have highest
hardness in the cutting tools industry. It often is used for high precision
area. It is used for machine Nonferrous metals.
(5)
And Ceramic Cutters also used
in many industries, but it only can be used for low cutting speed process
because of its large brittleness.
(6)
CBN Inserts. The hardness of
cbn insert is only second to diamond insert. However cbn insert is used for
machining ferrous metal, like hardened steel and cast iron parts.
When you choose the cutting tools, you can
choose depending on their performance and the character of the cutting tools
materials itself. When you machining ferrous metals , like hardened steel and
cast iron parts, cbn inserts will be your right choice. For cast iron parts,
especially choosing BNK30, it will has better performance than Seco CBN.
