BTA – Gas Turbine Upper Case – FINE BEAM
IMPROVE PRODUCTIVITY AND TOOL COST
The original process consisted of 3 spade drills of different sizes.
Utilizing Double Tube System we could increase productivity and reduce machine down time.
Using Double tube system we can get rid of time costly tool change and drill to depth in one go.
As a final result we managed to reduce the cycle time 5 times.
