Hardened steel is heat treated steel, after quenching and tempering hardness generally HRC45 above, and some even more than HRC60, because of its good performance, widely used in gear steel, bearing steel, die steel and other fields.
At the beginning,grinding as the final processing steps of hardened steel parts to improve the workpiece surface roughness and dimensional tolerances. With the increasing production of hardened steel parts, machinery manufacturers have emerged processing problems, grinding efficiency is too low, affecting the finishing efficiency.
With the continuous development of cutting technology, the development of the turning can be instead grinding tool materials - coated carbide tools, ceramic cutting tools and cubic boron nitride tool. The use of turning instead of grinding to become the final processing process,can have high-speed hard cutting hardened steel.
High-speed hard cutting has the following advantages: (1) high efficiency. Metal removal rate is 3-4 times the grinding; (2) dry cutting pollution is small; (3) the overall high precision parts. In the car grinding process, because most of the heat generated by cutting is taken away by the chip, it will not burn the surface as easily as the grinding surface and crack, can get a good surface quality and high position accuracy. (4) to reduce investment in machine to adapt to flexible production. In the case of the same productivity, lathe investment is only 1/3 of the grinder, and covers an area of small, low auxiliary costs. (5) the use of high-speed milling hardened die steel, can largely replace the EDM.
With the continuous development of modern technology, more and more hardened steel be used in the processing site. For the mass production of hardened steel when the problem occurs: the coating carbide tool is not wear resistance; ceramic tool collapse edge, tool costs higher and other phenomenons, although the cubic boron nitride tool more resistant to impact, but can only be used for finishing Snack knife depth of the case of small feed.
For small-volume production of hardened steel does not affect the overall processing efficiency, so do not pay attention to the effect of this problem. For high-volume production, the overall efficiency is low and the tool cost is increased. After the tool industry through continuous efforts to study the final Hualing superhard developed a non-metallic adhesive cubic boron nitride tool. Compared with the traditional cubic boron nitride tool, the biggest advantage is the strong impact toughness. To solve the mass production and large margin hard cutting hardened steel high-speed hard to make low-cost high-performance problems.
