Cone Crusher is an important componentof the crusher. It is mainly used
to crush hard and medium hard ore and rock. It is widely used in mining
machinery, metallurgy industry, construction industry, chemical industry
and other fields.
In order to ensure the long-term operation of the Cone Crusher,
high-manganese steel is often used as the main material of the Cone
Crusher, the hardness and durability are improved. However, the
high-manganese steel material Cone Crusher often has the following
difficult processingproblems in the processing:
(1) The work hardening of the Cone Crusher is serious, which aggravates
the tool wear and is easy to cause the toolto collapse and damage;
(2) Large cutting force and high cutting temperature, resulting in reduced
tool durability and variability of the workpiece, and low dimensional
accuracy;
(3) Due to the high temperature and high pressure between the cutting
tools and the chip, it is easy to form built-up edge and scale, which affects
the surface roughness of the workpiece, and it is difficult to ensure the
quality of the workpiece；

(4) Chips are not easily curled and broken during cutting, and chip
removal is difficult.
In the face of the difficult processing of the above-mentioned Cone
Crusher, Halnn Superhard has introduced a material of the solid CBN
inserts BN-K1 grade, which has been widely praised by the Cone Crusher
industry, Especially in the vertical machining Cone Crusher. Impact
toughness and wear resistance are 2-3 times higher than traditional
ceramic tools.
BN-K1 grade solid CBN inserts has a cutting depth of more than 7mm,
which is more resistant to impact than traditional ceramic tools and
ordinary cutting tools. Especially for the poorprocessing of casting
surfaces, it can be used to rough turning Cone Crusher without having to
polish the workpiece surface.
The toolperformance and cutting edge of the BN-K1 grade are developed
for the processingcharacteristics of high-manganese steel Cone Crusher.
They are highly targeted and cannot be used to machine ordinary mild
steel parts such as No. 45 mild steel
