IMPROVE TOOL LIFE

In parting off SNCM20 pinion gears on a CNC lathe, the previous solution faced tool life constraints, requiring frequent insert changes and resulting in lower efficiency.
By adopting Tungaloy’s AddForceCut system with the AH7025 grade, which combines a highly rigid self-clamping design for stable parting operations and a PVD-coated insert optimized for wear and fracture resistance, machining stability and tool longevity were significantly enhanced.
The number of parts machined per cutting edge increased from 500 to 800, achieving a 60% improvement in tool life and reducing downtime for insert replacement.
