TungCut – shaft – AH6235
IMPROVE PRODUCTIVITY AND TOOL LIFE
During internal grooving of SUS630 shafts for aerospace applications on a CNC lathe, the previous tooling struggled to deliver both consistent tool life and dimensional accuracy.
By adopting Tungaloy's TungCut system with AH6235 grade inserts, known for their high fracture resistance and optimized performance on stainless steels, the customer achieved stable machining with reliable chip control and improved size consistency.
As a result, productivity increased by 20% and parts per edge improved by approximately 17%, leading to fewer tool changes and enhanced manufacturing efficiency.
