Get to know our companies, and learn about the metalcasting/machining industry, by reading the Eagle Group Blog.
At the Eagle Group, we provide full-service metalcasting and CNC machining from start to finish. Part of our responsibility as a supplier is to estimate part price for each new product. One of the largest line items affecting final part price on any job is tooling. In metalcasting, tooling often comprises patterns used to create […]
The latest resource from the Eagle Group focuses on CNC machining and high-tech inspection. Our ebook CNC Machining Process Guide dives into the history, current practices and processes of CNC machining and advanced metrology. Perfect for anyone looking for a better understanding of precision machining in the 21st century, our new resource is available now […]
Grinding is a machining process using abrasive surfaces to remove material from metal workpieces. On the surface (pun intended) grinding may seem different than other machining processes, but it still works through chip formation and removal—just like sawing, milling, broaching and most other techniques. Grinding can produce surfaces conforming to rough or extremely close tolerances. […]
The Eagle Group is offering a new Ebook outlining the processes of CNC machining and advanced metrology. Titled “CNC Machining Process Guide: History, Current Practice and Processes of CNC Machining and Advanced Metrology,” the 25-page resource is intended to help manufacturing purchasers, OEM companies and engineers to get a better idea of how CNC machining […]
Broaching is a machining process using a cutting tool with teeth that increase in size from front to back. In many cases, an entire surface (or multiple surfaces) can be finished in a single pass with broaching. The technique is most often applied to finish holes, splines and flat surfaces. Broaching is a relatively new […]
Sawing is one of the oldest cutting techniques in use today, and innovations have allowed the process to keep up with advances in material, tolerances and product complexity. By definition, sawing is cutting a narrow slit in a workpiece by moving a toothed or abrasive cutting tool against the surface. Sawing is often used to […]
Boring may not sound like a very exciting topic, but don’t let names deceive you: boring is one of the most widely used techniques in machining, and one of the most reliable ways to finish holes. Boring is the process of enlarging and finishing pre-existing holes. The holes might have been cast, drilled or otherwise […]
Drilling is one of the most common techniques used in manufacturing to create holes. In contrast to other hole-making methods like boring, reaming and tapping, drilling is most often used to create holes in unbroken surfaces. In precision CNC machining, drilling can range in scope from simple, rough hole drilling to complex, multi-feature hole drilling.
Milling is one of the most common processes in CNC machining, most likely because it is so versatile. Using a single tool, machine shops can create nearly limitless shapes on the surface of a workpiece. Milling can completely transform a piece of metal stock into a finished part of nearly any complexity. The milling process in […]
