Helical milling cutter having multiple channels with different exit angles

摘要

"Helical cutter having multiple channels with different exit angles. A cutter of the top helical multiple channels (10) with at least two channels (20, 26).Each channel includes a plurality of inserts (38) stuck in it. The inserts (38) are all identical.The inserts (38) in different channels (20, 26) being trapped them at different angles of output (244 , 225 ) resulting in different effective axial lengths (ALS) of the inserts.This effective length different inserts in adjacent channels results in effective to all cutting and is particularly beneficial where the inserts in a given channel does not have the cutting edges overlappedS.
