TOYOKAWA―April 17, 2019―OSG Corporation today announced the release of the AM-EBT ball type carbide end mill and AM-CRE radius type carbide end mill for the roughing of additive manufacturing applications and mold overlay surfaces. Unlike conventional processing, where an object is formed by removing excessive materials, additive manufacturing deposits materials layer upon layer to create an object, which is a process similar to 3D printing. By utilizing 3D data, short delivery time and low production cost are made possible.
The AM-EBT ball type carbide end mill features a robust 3-dimensional negative geometry optimized for large depth of cut. The AM-CRE radius type carbide end mill is available in 6-flute or 8-flute configuration. OSG’s AM series end mills are recommended for materials in hardened steel, pre-hardened steel, stainless steel, heat-resistant alloy additive manufacturing applications and built-up welding parts.
The AM-EBT and AM-CRE are coated with OSG’s original DUROREY coating. The super heat resistant layer and ultra-fine periodic nano-layer structure of the DUROREY coating provides superior toughness while maintaining high heat resistance and abrasion resistance. The DUROREY coating also suppresses chipping in high hardness milling and enables long tool life even in the milling of built-up welding parts with large depth of cut.
