IMPROVE PRODUCTIVITY AND TOOL LIFE

In internal grooving of SUM23 valve components on a dedicated machine, the previous tool struggled with dimensional accuracy, unstable chip evacuation, and insufficient surface quality, particularly when a small internal diameter and deep overhang were required.
By introducing TungShortCut equipped with the AH7025 grade—renowned for its high wear resistance and toughness—the machining process achieved stable groove dimension control and nearly eliminated chip wrapping.
As a result, tool productivity improved by over 270%, and tool life doubled, with no surface peeling observed even after processing 1,000 parts per cutting edge.
