VariableMeister- Ball screw nut- AH725
IMPROVED TOOL LIFE
In the slot finishing process of ball screw nuts, a competitor’s general-purpose 2xDC end mill had been used previously. By switching to the VariableMeister short type 1xDC end mill, surface finish accuracy improved and became more consistent. Tool life was also extended by 1.4 times.
The VariableMeister was adopted; however, the customer continues testing with the aim of further improving machining efficiency.
