ThreadMilling – Manifold Blanket – AH725
IMPROVED PRODUCTIVITY & COST REDUCTION
Tungaloy recommended ThreadMilling, instead of HSS taps. Improvement Result: Improved cycle time by 25% and tool cost by 76%. Tool change time also decreased, reducing machine downtime. This saved additional investments for new machines, which was initially planned. In addition, ThreadMilling tool generated far lower cutting forces, compared with a HSS tap, eliminating the concern for workpiece movement during machining.
