TungMeister – Valve Block – AH715
IMPROVED PRODUCTIVITY AND QUALITY
In face finishing of an SS400 machine component, the customer faced an issue where surface scratches from a competitor’s Ø10, 4-flute end mill became visible after plating.
By adopting the Ø12, 6-flute VFM (AH715) featuring a wiper edge design, a 67% increase in feed rate was achieved while maintaining a smooth and uniform surface finish.
As a result, the post-plating scratch issue was eliminated, simultaneously improving downstream quality stability and overall productivity.
