Inconel 718 vs Inconel 625: Different Alloys, Different Machining Strategies Inconel 718 and Inconel 625 are the two most widely machined nickel-based superalloys in aerospace, oil and gas, and power generation. While they share a common nickel-chromium base, their precipitation-hardening mechanisms and mechanical properties create distinctly different machining behaviors. Treating them as interchangeable is a …

Chip Control in CNC Turning: Chipbreaker Selection for Steel, Stainless, and Aluminum Chip control is one of the most underestimated factors in CNC turning productivity. Poor chip control leads to tangled bird’s nests that wrap around the workpiece, scratch finished surfaces, damage cutting edges, and create serious safety hazards for operators. Selecting the correct chipbreaker …
