The SMART MIRACLE end mill series are highly valued by many customers for the improvement in machining efficiency and the longer tool life when machining titanium and heat-resistant alloys. Now, MITSUBISHI MATERIALS have expanded the series with a 2 flute ball nose type, VQN2MB, and the 4 flute ball nose types VQN4MB and VQN4MBF. They are specially designed for machining Ni-based super heat-resistant alloys that are widely in aircraft components.

 

Main features of VQN2MB, VQN4MB, VQN4MBF

1. The (Al, Ti, Si) based coatings maintain their film hardness and heat resistant properties under the harshest of conditions, making it highly suitable to applying it to end mills that machine heat resistant super alloys.

2. The ball end cutting edge rake angles have been optimised for consistent contact. Additionally, this improves fracture resistance for stable, high efficiency machining.

3. VQN4MBF with a full 4-flute end geometry, is ideal for 5 axis machining. Whereas the new VQN4MB, with 4 side flutes displays a special end geometry with only 2 ball end flutes. This design provides extra space for excellent chip evacuation during rough machining.
