The advantages of superhard cutting tool is avoiding grinding, and improve the production efficiency. Hard turning can realize high speed machining, and 80% of the heat will be taken away together with the chips, which will help save the costs on the grinding wheel. But some manufacturers thought it is impossible that hard turning high hardness component in the past. The main reasons are hard turning need good technology system and machine tools.
Halnn Superhard is one enterprise that producing superhard tools, the leader of superhard materials tools in China. Since established, we always insist “High Precision, More professional, High Efficiency”, and already become the famous brand in China. In current times, Halnn tools are widely used in hard turning industry. With more than 10 years experience, Halnn conclude some problems that need to note when hard turning the high hardness workpiece:
1.The component
Hard turning is suit for the workpiece which has small “length-diameter” ratio (L/D), For example, the L/D of the workpiece without support need no more than 4:1, the L/D of the workpiece with support need no more than 8:1. The insert hanging outside will no more than 1.5 times of height of the tool holder.
2.The rigidity of the machine tool
The machine tools will have good rigidity in recent years, and are enough to obey hard turning. In most situation, the condition of the machine tool will be very important for hard turning process.
3.The cutting tools
Superhard cutting tool perform best when hard turning high hardness workpiece, and can meet all the requirements. And Zhengzhou is the center of the superhard cutting tools materials. For example, BN-S20 from Halnn not only can be used for in continuous turning condition, but also perform well in interrupt turning condition.Nowadays, more and more high hardness materials appear, superhard materials industry also continue to researching new materials to catch up the development. The cutting tools can be used for both hard turning high hardness workpiece, but also can machine common gray cast iron with high cutting speed, and improve the efficiency several times.
4.Cutting fluid costs
When using superhard cutting tools, you’d better avoid the cutting fluid, use dry cutting. Or the insert will be easily damage when meet the heat attack. Avoiding the cutting fluid not only can reduce the costs on each component, but also can reduce the pollution, and protect the environment.
