Product Positioning
Our[Product 250C40R-C60HN09] Series Solid Carbide End Millstarget modern, high-efficiency machining. They actively boost your productivity when millingaluminum alloys,die steels, andstainless steel, thereby helping you lower the cost per part.
Core Technology Explained
First, we construct the tool body from sub-micro grain carbide. This choice grants the tool exceptional toughness and impact resistance. Following this, we apply a specialized multi-layer PVD coating to the surface. This coating expertly balanceswear resistancewith lubricity, which is key to extendingtool life.
Furthermore, we optimize the flute geometry for specific materials. For instance, when machiningaluminum, the high helix angle and polished edges ensure chips flow away smoothly. This design effectively prevents material from sticking. Conversely, forroughing cavitiesindie steel, the variable helix design dramatically reduces vibration. As a result, you can confidently use more aggressive cutting parameters.
Applications & Customer Value
Thanks to these features, this end mill series excels in several key sectors:
Aerospace: It is ideal for thehigh-speed finishingof complex aluminum parts.
Mold & Die: It reliably handleshigh-efficiency roughingin deep, pre-hardened steel cavities.
General Machining: It consistently performsshoulder and contour millingon stainless steel.
In summary, adopting this tool delivers three measurable benefits to your operation:
It increases yourmetal removal rate, which directly shortens cycle times.
It achieves a superiorsurface finish, minimizing the need for post-processing.
It lowers yourTotal Cost of Ownership (TCO)through predictable, extended performance.
