Cutter Turning Tools for Cutting Hardened
overview
Folding has high thermal stability and high temperature hardness
The heat resistance of CBN can reach 1400~1500℃, and the hardness
is the normal temperature hardness of Al2O3/TiC ceramics at 800℃.
Therefore, when the cutting temperature is higher, the processed
material will be softened, and the hardness difference between the
tool will increase, which is conducive to the cutting process, and
the tool life will not be affected.
Folding has high chemical stability
CBN has a high antioxidant capacity, no oxidation phenomenon at
1000 ° C, and iron materials at 1200~1300 ° C does not occur
chemical reaction, but at 1000 ° C will produce hydrolysis with
water, resulting in a large number of CBN wear, so with PCBN tool
wet cutting need to pay attention to select the type of cutting
fluid. Under normal circumstances, wet cutting does not
significantly improve the life of PCBN tools, so dry cutting is
often used when using PCBN tools.
Folding has good thermal conductivity
The thermal conductivity of CBN material is lower than diamond but
much higher than carbide, and with the improvement of cutting
temperature, the thermal conductivity of PCBN tool continues to
increase, so that the heat at the tip of the tool can be quickly
transmitted, which is conducive to the improvement of workpiece
processing accuracy.
Folding has a low coefficient of friction
The coefficient of friction between CBN and different materials is
between 0.1 and 0.3, which is much lower than the coefficient of
friction of cemented carbide (0.4 to 0.6), and it decreases
slightly with the increase of friction speed and positive pressure.
Therefore, the low friction coefficient and excellent anti-bonding
ability make it difficult to form a retention layer or chip nodules
when cutting CBN tools, which is conducive to improving the quality
of the machined surface.
Folding is suitable for high-speed and ultra-high-speed cutting
technology
PCBN tools are most suitable for high-speed cutting of cast iron,
hardened steel and other materials. From the PCBN tool cutting cast
iron and hardened steel tool back tool wear and cutting distance
relationship can be seen: when the cutting speed exceeds a certain
limit, the higher the cutting speed, PCBN tool back tool wear speed
is smaller, that is, high-speed cutting tool life is higher, this
feature is especially suitable for modern high-speed cutting
processing.
