The advantages of dry cutting and the cutting tools choice
Dry cutting is a method of protecting environment and reduce the costs. And dry cutting need stop the fluid while ensure high efficiency, high quality and high tools durability. So it needs that the cutting tools and the lathe have good performance.
The advantages of dry cutting comparing with wet cutting
(1) Reduce the costs
At present, the costs of cutting fluid, maintenance and recycling costs will account 13% -17% of the workpiece cost, while the tool costs only 2% ~ 5%. And if we use dry cutting, the production costs can be saved by1.6%.
(2) Reduce the pollution
With dry cutting process, the chips can be recycled, don’t need to be treated as toxic and hazardous materials, protect the environment and reduce the costs.
(3) Offer good working environment
Dry cutting will offer good environment for the workers, which will not harm their health.
The main effect of the cutting fluid is Cooling, lubrication, excretion. If without fluid, the cutting tools need to obey the high temperature in the process. That means, the tools need to excellent red hardness and good wear resistance. And it also needs the cutting tools can work with high cutting speed. So the tools that can satisfy all the requirements are mainly Ceramic Cutters and CBN Inserts.
Both ceramic cutters and cbn inserts have high hardness, excellent wear resistance, but it is easily brittleness, and will be easily chipping when meet interrupted turning condition. For this occasion, you can choose BN-H10 and BN-H21 PCBN Insert, which not only can be used for high speed dry cutting, but also can make sure the good surface quality.
BN-H10 and BN-H21 is researched for interrupted and continuous turning condition of the hardened steel.
Summary
In the modern manufacturing industry, dry cutting has been widely used in automotive, machine tools, military, mold and other fields, but in terms of dry cutting is more suitable for cutting hard materials, soft materials for the workpiece processing also need cutting fluid support, But I believe in the continuous development of the tool industry, will gradually overcome the difficulties, so that the rapid manufacturing industry to achieve green manufacturing.
