CBN Grooving Tools For Cast Iron Cylinder liner Cutting Tools/Cylinder Tools
1. Advantages of Halnn CBN Grooving Tools
1.Comparing with other CNC tools, it can realize high cutting speed and improve the process efficiency.
2.Comparing with coating carbide insert, the tool life will improve about 9~15 times, and the costs only about 7 times of coating pcbn inserts, which is more economic.
3.With Halnn CBN Grooving Tools, the surface roughness and precision both get improved.
4.We can offer customized service as the customers' requirements.
2. Halnn CBN Grooving Tools for Cylinder liner
Most cylinder liner are made of abrasive resistant cast iron, such as boron cast iron, alloy cast iro, ect. All of them have hard pots, so it will wear rapidly with tungsten carbide tools, and also some materials can't machine with tungsten carbide inserts.
CBN tools, as one new superhard cutting tools, make it possible process the wear resistant cast iron with high hardness and make sure the high precision, good surface roughness and improve the cutting efficiency.
Halnn has researched new cbn grade BN-S300 and BNK30 specific for gray cast iron machining, both can be used for roughing and semi-finishing process. The following is cutting parameters of BN-S300 and BNKK30:
| Machining Materials | Process | Cutting Speed Vc(m/min) | Cutting Depth ap(mm) | Feed Rate Fr(mm/r) | Recommend CBN Grade |
| Gray Cast Iron | Roughing | 400-1200 | 1-10 | 0.2-1.0 | BN-S30, BN-S300 |
| Finishing | 600-2000 | ≤1 | 0.05-0.3 | BNK30, BN-K10, BN-K20 |
