AddForceCut – Valve – AH6235
IMPROVE PRODUCTIVITY AND TOOL LIFE
In the parting off process of Valve components made from SUS 316L stainless steel on a CNC lathe, the previous tool struggled with producing long, unbroken chips that impacted process stability and chip evacuation.
By adopting Tungaloy's AddForceCut, featuring a rigid self-clamping system and AH6235 PVD grade optimized for stainless steel, the customer achieved reliable chip breaking and improved machining consistency.
This resulted in a significant productivity increase of over 260% and a 25% enhancement in tool life compared with the previous solution.
