AddForceCut – valve – AH7025

IMPROVE PRODUCTIVITY

In external grooving of SS400 valves on a CNC lathe, the previous tool encountered significant vibration and productivity limitations at higher feed rates, especially with deep parting operations.
By introducing Tungaloy’s AddForceCut with the AH7025 grade, featuring a high-rigidity self-clamping system and excellent wear resistance, stable and chatter-free machining was achieved even at feed rates up to 0.15 mm/rev.
As a result, productivity was boosted by 300% compared to the previous solution, allowing for efficient and reliable processing across various part sizes and work materials.
