Powder metallurgy(also called PM) is a kind of material that can save materials, energy, and suit for mass production with less cutting, high-efficiency metal forming process , and has been widely used in automobiles, motorcycles, agricultural machinery production and other industries. In recent years, more and more automotive components use powder metallurgical process.
Powder metallurgical component usually has similar shape,only have less allowance, but because of the porous structure, the Powder metallurgy component is difficult to machine.Porosity will cause mirro-fatigue on the cutting edges.The continuous impact can lead to small cracks on the cutting edge.These fatigue-grained castings increase until the cutting edge collapses. And also because of the porosity, we get the materials with the Macro hardness HRC20~35, however the Micro hardness will reach HRC60. And these praticle will lead to the insert tips wear seriously. With this situation, you can choose Halnn CBN Insert, which not only can machine the powder metallurgy component Effectively, but also can make sure the precision and the roughness requirements.
As the predecessor of China superhard cutting tools, Halnn always focus on the researchment of the cutting tools for the brittle hard materials and difficult to machine materials. In recent years, rely on the National Key Laboratory for superhard materials and Henan University of Science and Technology, the innovative PCBN Tool have been widely used, and BN-K50 and BN-K10, as the special cbn grade for machining powder metallurgy, have excellent performance.
Both BN-K50 and BN-K10 belong to Brazed PCBN Insert, and have excellent abrasive resistance, suit for machining the powder metallurgy component with large qty. Comparing with traditional cutting tools, not only the cutting speed can be improved, but also the tool life can be improved several times.
For example, machining the Pulley with powder metallurgy,
Machining Condition: Semi-Interrupt turning, Hardness, HRC38, Selected Insert BN-K50 DCGW11T304, Dry Cutting.
with same cutting condition, the tool life of Halnn BN-K50 can be 1.5 times of some brand CBN Insert.
