The Ultimate Guide to Aluminum CNC Mills
In this article, we’ll discuss two main types of machines: CNC routers (which can cut soft metals like aluminum) and CNC metal mills (designed to handle harder metals like steel, stainless steel, brass, titanium, magnesium, and more). I’ll step you through my hands-on experience with each machine, comparing key features like power, work area, and ease of use, so you can make the right choice for your project.
Understanding CNC Machines for Aluminum
CNC (Computer Numerical Control) machines have revolutionized the manufacturing industry, allowing for precise and efficient machining of various materials, including aluminum. Aluminum is favored for its lightweight, corrosion resistance, and excellent machinability. However, the choice between a CNC router and a CNC mill can significantly impact the quality and efficiency of your projects.
