1. When machining pump, the components have high hardness and large working allowance, how can we choose the cutting tools for machining this type pump parts?
A: Most pump components belong to castings, and the allowance is decided by the workpiece size. If the workpiece is large, the allowance will also increase. Specific for this situation, we’d pay more attention on the cutting tools performance and the hardness. Halnn researched BN-K1 solid cbn insert specific for this type pump parts. BN-K1 cbn perform well on machining pump parts. BN-K1 use non-metal as blinder, improve the impact resistance, realize large working allowance turning, and it will not appear chipping problem. The tools life will be improved obviously. And the tool costs will be reduced.
2. Pump components belong to casting parts, it will exist casting defects and is difficult to machine, how can we choose the cutting tool materials?
The materials will be different depending on different pump components. For example, industry pump will use high chromium cast iron as the main materials, however water pump will use gray cast iron. High chromium cast iron is difficult to machine, so difficult to machine is specific for industry pump which is made of high hardness cast iron. For this materials components, we usually choose cbn insert.
High Chromium Cast Iron components has high hardness and excellent wear resistance, and usually has casting defects, so they are difficult to machine. Because cbn insert is the hardest cutting tools materials for machining ferrous metals, it will be the right cutting tools for machining pump components. Halnn researched BN-K1 Solid cbn insert specific for high hardness cast iron. It performs well comparing with other international cbn, such as Seco, Sumitomo ect.
