The (Al, Ti, Si)N-based coatings maintain their film hardness and heat resistant properties under the harshest of conditions making it a highly suitable coating for end mills machining heat resistant super alloys.
Featuring the new (Al, Ti, Si)N-based coating which provides excellent wear resistance combined with the optimal number of irregular helix flutes to greatly dampen vibration enabling stable, efficient machining.
The corner radius cutting edge rake angles have been optimized for consistent contact. Additionally the structure of both the 2 and 4 flute end mills have been strengthened.
When compared to 2-flute types, end mills with 4 flutes have a longer tool life and provide higher efficiency machining. In addition the new types have a much improved chip disposal rate to prevent clogging.
Now available is the new VQN4MBF with a full 4-flute end geometry, ideal for 5 axis machining. The new VQN4MB, with 4 side flutes displays a special end geometry with only 2 flutes, designed with extra space for excellent chip evacuation during rough machining.
Excellent wear resistance when machining heat resistant super alloys.
Due to the optimized number of flutes and the enhanced R corner shape, fracture resistance is improved and tool life is more than doubled compared to conventional products.
Cutting time has been reduced due to an increased feed rate and an excellent resistance to fracturing during slotting.Ideal for machining heat resistant alloys typically used in the aerospace industry.
Both VQN4MBF and VQN4MB have more than four times the wear resistance of conventional products.
