DrillMeister -Shaft flange- long over hang solution
IMPROVE PRODUCTIVITY
This case involves improving machining efficiency in shaft work.
For a flanged shaft, a 45 mm overhang (6.8×D) was required to avoid interference with the flange surface during drilling.
We proposed and evaluated the DrillMeister TUNGFLEX type, which proved highly effective.
As a result, machining efficiency was approximately doubled compared with the previous setup, while maintaining the same tool life — successfully machining 1,000 parts (two holes per workpiece) without any issues.
