The processing of the rollers requires roughing, semi-finishing and finishing. Each process requires a certain difference in the processing requirements which will require that the most suitable machining tools and parameters be selected to meet the requirements of the drawings. Based on this, our customers make research on the cutting technology to search the most suitable cutting tools for machining the nickel-based alloy spray layer.
1. The cutting process of the nickel-based alloy sprayed layer
In the initial machining, due to the lack of processing experience on nickel-based alloys, it is very difficult to use the diamond wheel to cut it primarily, and it is not only inefficient but also relatively costly high. It can be seen that traditional methods is very inappropriate. After all the analysis, we can make sure that CBN tool should be the right tool to obtain the required precision.
CBN Tool not only has very high hardness, strength and low density, and when the hardness at room temperature HRA92, it also has a very good wear resistance and machine ability, it can machine the hardened cast iron and hardened steel which hardness will reach HRC65. The tool has a bending strength of between 700 and 900 MPa, and its thermal shock resistance is relatively good, and the fracture toughness value is better than other ceramic tools, and can be used to process rough parts with higher strength. CBN tool itself has a very high hardness, thermal shock resistance and wear resistance, is the ideal tool for cutting hardened steel and other materials.
2. Notes on the use of boron nitride tools
Although the boron nitride material is very suitable for cutting the material, but because of its brittle characteristics and other issues, which makes that we need to pay attention to many problems when we use it.
(1) The machine lathe needs to have good rigidity
(2) Reduce the impact of the workpiece
(3) Cutting amount need to be determined according to the actual situation to ensure the quality and cutting efficiency
3. Conclusion
In short, CBN Insert will be the most right cutting tools for machining surfacing tool, which will also have excellent cutting performance. And we also need to choose the cutting tools depending on the different requirement. Also when you choose the tools, please ask the professional engineer, they will give you good choice.
