New chatterfree solid carbide endmills from ISCAR
ISCAR is introducing a new evolution of the CHATTERFREE solid carbide endmills for high speed/trochoidal milling and finishing operations with specially designed multi-flute endmills with different flute helix angles and variable pitch.
The unique geometry of the different flute helix and the variable pitch EC-H…CF line provides the best chatter free tool for high speed/trochoidal milling, featuring high productivity on most material types such as alloyed and stainless steel, and high temperature alloys.
Trochoidal milling is a programming technique applying a small radial width of cut, high cutting speed and feed per tooth. It provides long tool life and high productivity on most materials, but especially on high temperature alloys where chipbreaking and heat disposal is usually very problematic.
The new EC-H… CF endmills are divided into two families:
- EC-H7…CF featuring 7 flutes in 6-20 mm diameters
- EC-H.. CF featuring 6-20 flutes in 6-20 mm diameters
The EC-H7…CF 7 flute tools feature more open gullets than the 6-20 flute tools. Therefore EC-H7…CF tools can machine at radial width of cut (ae) of up to 0.1xD, while the EC-H.. CF tools can machine at ae of up to 0.06xD.
Both endmill families are made from the hard PVD coated grade IC902. This grade provides long tool life, and combined with the unique geometry, features excellent surface finish on most workpiece materials.
