TungCut – construction machinery parts – AH7025
IMPROVE TOOL LIFE
In external grooving of S45CF construction machinery parts on a CNC lathe, the previous tool's limited tool life was a concern, leading to frequent insert changes.
By adopting Tungaloy’s TungCut system equipped with the AH7025 grade insert, which features a nano-multilayer PVD coating for superior wear and chipping resistance, the customer achieved much greater edge durability.
This upgrade extended tool life to over 1,000 parts per cutting edge—approximately a 67% improvement compared with the prior solution—significantly reducing downtime and boosting efficiency in production.
