VariableMeister- Ball screw nut- AH725
IMPROVED TOOL LIFE
In the slot roughing process of ball screw nuts, a competitor’s general-purpose 2DC end mill had previously been used, but there were issues with short tool life. By switching to the VariableMeister short type 1DC end mill, chatter and wear were suppressed, resulting in a 1.7 times longer tool life.
