Size expansion of the VF-MHV vibration control end mill and new
VF-6MHVRB vibration control radius end mill

January 05, 2009
Mitsubishi Materials Corporation has recently developed and manufactured an additional 4 sizes for Impact Miracle vibration control end mill series, VF-MHV. Additionally, a new range of the Impact Miracle series, the 6 flute vibration control radius end mill VF-6HVRB has also been developed. These will start to be sold by Mitsubishi Materials Tools Corporation (President: Osamu Takata, Headquarters: 1-6-1 Yokoami, Sumida, Tokyo).
VF-MHV / VF-6MHVRB When machining difficult-to-cut materials such as stainless steel and titanium alloy that are mainly used in aerospace parts applications, machining with high speeds can often result in vibrations. To solve this problem, Mitsubishi Materials released the VF-MHV vibration control end mill that employs an irregular helix flute geometry that is designed by optimizing a combination of different helix angles. The series has now been expanded to include an under cut type (1) suitable for deep slotting and an additional 4 sizes for the VF-MHV to cover a broader range of machining applications.

Additionally, in response to an increasing demand for even higher efficiency when machining with smaller depths of cut, the 6 flute vibration control radius end mill VF-6MHVRB featuring an irregular helix flute geometry and corner radius geometry that is increasingly demanded in aerospace parts applications, has been now added to the series.

Features of the VF-MHV and VF-6MHVRB

1.
Use of an irregular helix flute geometry assists in preventing vibrations even when machining difficult-to-cut materials and thin walled parts. This results in reduced vibrations leading to higher machining efficiency.
2.
The VF-MHV under cut type employs a curved cutting edge on the shank side of the peripheral cutting edge to reduce steps when machining deep vertical walls.
3.
The VF-6MHVRB has 6 cutting edges to achieve higher efficiency especially when shoulder milling.
4.
Impact Miracle coating with high heat resistance is applied. This allows higher film hardness, higher oxidation resistance and a lower friction coefficient, making it possible to achieve high precision, high quality machining.

 

< Word explanation >
(1)Under cut type:
  • Tool geometry whose shank diameter is smaller than the cutting edge diameter.
