Metal fatigue is the cracking and eventual failure of a metal workpiece under the stress of perpetual loading, a type of continual loading known in the industry as cyclic loading. Fatigue resistance in metal parts is the other side of the coin: it represents a part’s ability to avoid cracking and failure under cyclic loading. […]
Just a year since being fully acquired by Eagle Alloy, the Eagle CNC team is showing their resilience and ability to thrive in their new environment It’s been a year since Eagle Alloy fully acquired Eagle CNC, and a lot has changed. The companies are growing closer together in terms of shared systems and shared […]
The word ‘tempering’ generally means acting as a counterbalancing force, moving an object (or a situation) away from the extremes, toward a more balanced state. The same principle applies to heat treatment: when we temper a metal part, we are adjusting the proportion of one mechanical property against another. Specifically, we are increasing ductility while […]
Bill Seyferth is the founder of Westech Corp., which now operates as Eagle CNC. In recent years, this state of the art machine shop has worked alongside Eagle Alloy and Eagle Precision as part of Muskegon’s Eagle Group, a manufacturing team providing casting-to-completion services for a variety of customers. As Bill retires from the company […]
Toughness is a mechanical property that measures the amount of energy a material can withstand, or absorb, before fracturing. In the context of other mechanical properties, toughness for steel products represents a balance of strength and ductility. As a material term, toughness can sometimes cause confusion: two very different materials can both be considered tough. […]
The heat treatment known as annealing encompasses a group of processing heat treatments. Unlike thermal processes that are used to improve the strength and wear resistance of a part (such as hardening heat treatments), processing heat treatments are used to prepare a workpiece for further manufacturing processes. Chiefly, this means improving a material’s responsiveness to […]
Imagine a medieval blacksmith hammering a sword fresh out of the fire. With the weapon still red-hot, he dunks it in water. The water hisses and boils around the submerged steel as it turns color from glowing orange to grey. This iconic scene of rapidly cooling a workpiece is called quenching, or quench hardening, and […]
Internal stresses form naturally during many manufacturing processes. Machining, stamping and welding, for example, are common manufacturing methods that augment the amount of stress in a material’s fabric. And although stress build-up is a natural byproduct of these processes, too much of it leads very commonly to part distortion. Most of these stresses must therefore […]
Joining multiple metal parts together into a single, cohesive unit is an indispensable process to manufacturing. Bolts, screws, and adhesives are often used to unite separate parts, but many applications call for a more solid connection. Thanks to the craft of welding, manufacturers are able to effectively create a single part from multiple components. Casting […]
