Product Description
Used for Hardened steel, high hardness Difficult to process materials use edit CBN content (%) - Binder type - main purpose ~ 60-TiN-hardened steel ~ 70-TiC-cast iron ~ 70-Al2O3-cast iron ~ 90-AlN-high strength cast iron ~ 80-Co-heat-resistant alloy steel cast iron Application areas edit Suitable for high-speed and ultra-high-speed machining technology PCBN tool is most suitable for cast iron, hardened steel and other materials, high-speed machining. The
cutting speed and the cutting distance of the tool can be seen from the
cutting of the cast iron and the hardened steel by the PCBN tool. When
the cutting speed exceeds a certain limit, the cutting speed is higher
and the cutting speed of the PCBN tool is smaller, Cutting tool life is high, this feature is particularly suitable for modern high-speed machining. The best tool material for hard machining The
finishing of the hardened parts (hardness HRC55 or higher) is usually
done by grinding, but with the development of tool materials and the
improvement of the machining accuracy of lathes (especially CNC lathes),
the parts are replaced by hard cutting instead of grinding The final processing has become a new finishing process, this car to the grinding process has the following advantages: (1) can improve the processing flexibility, breaking the grinding
wheel grinding restrictions, by changing the cutting edge and knife way
can be processed out of different geometric shapes of the workpiece; (2) the environmental problems in cutting are becoming more and more
serious. The waste liquid and waste produced by grinding are more and
more difficult to be treated and cleaned, and it is harmful to human
body, and hardening is not necessary to add coolant. (3) high cutting efficiency, short processing time, equipment investment costs are small, can reduce processing costs; (4) the removal of the same volume of energy consumed by only 20% of
grinding, resulting in less heat cutting, the processing surface is not
easy to cause burns and small cracks, easy to maintain the integrity of
the surface properties of the workpiece; (5) the same metal removal rate in the case of hard cutting more energy than grinding grinding. The
tool materials commonly used for hard cutting are ceramic, TiC coated
inserts and PCBN tool materials, but PCBN is the best tool material for
hard turning under higher speeds (above 1000m / min). Such
as in the automotive gearbox synchronizer sets of fork fork (material
for the 20CrMnTi, hardness HRC58 ~ 62) processing using the car after
grinding, the efficiency increased more than 4 times the processing cost
to reduce the original grinding process 1/3 to 1 / 2.
