Flat/Ball Nose 1/8 Inch, 1/4 Inch, 6mm, 8mm Tungsten Carbide End
Mill For Iron Steel
The main features are as follows:
a. It can withstand high temperature, and can still maintain good
cutting performance at about 800-1000 ℃. It can choose a cutting
speed 4-8 times higher than high-speed steel when cutting.
b. High hardness at normal temperature and good wear resistance.
c. The bending strength is low, the impact toughness is poor, and
the blade is not easy to sharpen.
Commonly used cemented carbide can generally be divided into three
categories:
① Tungsten-cobalt cemented carbide (YG)
Commonly used grades YG3, YG6, YG8, where the numbers indicate the
percentage of cobalt content, the more cobalt content, the better
the toughness, the more resistant to impact and vibration, but will
reduce the hardness and wear resistance. Therefore, the alloy is
suitable for cutting cast iron and non-ferrous metals, and can also
be used for cutting high-impact blanks and hardened steel and
stainless steel parts.
② Titanium cobalt carbide (YT)
Commonly used grades are YT5, YT15, YT30, the number indicates the
percentage of titanium carbide. After the carbide contains titanium
carbide, it can increase the bonding temperature of the steel,
reduce the friction coefficient, and slightly improve the hardness
and wear resistance, but reduce the bending strength and toughness,
and make the properties brittle. Therefore, the Alloys are suitable
for cutting steel parts.
③ General hard alloy
Add appropriate amounts of rare metal carbides, such as tantalum
carbide and niobium carbide, to the above two cemented carbides to
refine their grains and improve their normal-temperature hardness
and high-temperature hardness, wear resistance, bonding temperature
and oxidation resistance , Can increase the toughness of the alloy,
therefore, this kind of cemented carbide knife has better
comprehensive cutting performance and versatility, its grades are:
YW1, YW2 and YA6, etc., because its price is more expensive, mainly
used for difficult Processing materials, such as high-strength
steel, heat-resistant steel, stainless steel, etc.
