A 0.500-inch solid carbide end mill that lasts an eight-hour shift machining 4140 can lose its corner geometry in under fifteen minutes when cutting solution-treated Inconel 718.  Managing heat is one of the biggest challenges when machining high-nickel superalloys. For aerospace machining specialists, protecting tool life begins with the machining plan, from selecting the right… Continue reading Overcoming Tool Wear: Best Practices for High-Speed Milling of High-Nickel Alloys

At Cer-Mac Inc., we treat temperature as a major engineering variable rather than a passive  environmental byproduct. In a facility specializing in tight-tolerance components, precision is governed by the laws of thermodynamics: a part measured at 7:00 AM in a non-temperature controlled environment might be perfect, but by mid-morning, that same component could measure ten… Continue reading The Impact of Thermal Expansion on Precision Machining Accuracy
