T-A® Coating Options
|
| TiN |
| |
TiN is the original coating offered by AMEC. Its longevity and wide use are a tribute to its success in the cutting tool market. |
| |
| TiCN |
| |
TiCN is the hardest coating AMEC stocks. Its high hardness provides increased wear resistance over TiN coating making it suitable for harder, more wear resistant materials. |
| |
| TiAIN |
| |
TiAIN has the highest heat threshold of the coatings that AMEC stocks, allowing for much higher drilling speeds. It has been proven successful in both cast iron and steel applications. |
| |
| T-A® Insert Grades |
| |
| HSS (CPM-M4) |
| |
This tool steel grade possesses the highest material toughness to resist shock and vibration loading. It will drill the majority of steels and cast irons in the industry that are below 280 BHN. |
| |
| Super Cobalt (CPM-T15) |
| |
This tool steel grade exhibits midrange wear resistance and toughness. It is more wear resistant, but slightly lower in toughness (more brittle) than standard M4 HSS. This grade will provide increased wear resistance in any ferrous or non-ferrous application, especially materials within the 280-359 BHN range. |
| |
| Premium Cobalt |
| |
This is the most wear resistant tool steel AMEC offers. It possesses reduced material toughness making it more susceptible to fracture from shock and vibration. It is recommend for hard materials (350-500 BHN) as well as abrasive materials. High machine tool and fixture rigidity are required in order to consider premium cobalt as a reliable cutting material. |
| |
| C5 Carbide |
| |
This carbide grade is for general use in steel applications. It offers exceptionally high wear resistance. High machine tool rigidity is required. |
| |
| C2 Carbide |
| |
This carbide grade is for use in non-ferrous applications (high temperature alloys, stainless steels, aluminums, cast irons). It offers exceptionally high wear resistance. High machine tool rigidity is required. |
| |
| C3 Carbide |
| |
This carbide grade is for use in gray cast iron applications. Inserts made from C3 carbide are stocked with AMEC's CI geometry and TiAIN coating. It offers exceptionally high wear resistance. High machine tool rigidity is required. |
