The major difficulties in machining Inconel 718 lie in its material properties. Inconel alloys are known for their resistance to oxidation and corrosion. When heated, Inconel forms a thick, stable, passivating oxide layer protecting the surface from further attack. Repeated machining motions (pecking or drilling) on Inconel can cause work hardening and place extra wear and tear on the tools. This makes Inconel difficult to shape and to machine by using traditional methods. ☑️ Inconel 718 Machining Information Inconel 718 Machining Information Material Inconel 718 Dimensions Φ1 (tool spec.) x 20mm [aspect ratio : 20] Methods Deep hole drilling Machine Tool Buffalo MCU-5X Max.
