High speed turning grade
Utilising a synergy of different coating technologies and matching carbide, UE6105 offers "2 in 1 technology" by combining two types of CVD coatings that can deliver a machining performance that fully satisfies today's modern production requirements.
The combination of carbide substrate and specially designed coating layers allows UE6105 to be chosen for high speed productivity up to 400 m/min on mild, carbon and alloy steels.
The smooth top layer is a CVD nano-texture coating consists of TiCN, which has been made finer and more uniform by the use of a process called crystal growth control technology. Additionally, this technology also allows a much more uniform Al2O3 layer that provides the important higher wear and fracture resistance, thus ensuring extended tool life at the high speeds required for a P05 grade.
The side faces have a "Black super-even coating". This is extremely smooth and stabilises wear development during machining, due to reduced friction, and helps achieve higher dimensional accuracy of the finished component. Furthermore, the reduced friction prevents abnormal damage, such as weld chipping and allows stable machining over prolonged periods.
The carbide substrate has also been conceived to work in tandem with the coating layers to provide the best combination. The substrate has an ideal internal composition and distribution of hardness and toughness that offers plastic deformation resistance nearer the surface but also provides the overall toughness required in the core to prevent insert breakage under heavy loads.
UE6105 is available in 54 different combinations of ISO geometry and Mitsubishi's versatile chip breaker range.
