Aluminum is one of the most commonly used industrial materials. Its strength-to-weight ratio makes it ideal for several applications in the marine, aerospace, and railway industries, all of which value lightweight durability. It’s also a favorite in the automotive industry, especially for its thermal and aesthetic appeal. Regardless of the application, aluminum needs to be cut precisely, and that’s where CNC routers come in.
Computer numerical control (CNC) routers are automatic three-dimensional cutting and milling machines that, compared to other cutting methods, minimize material waste and reduce errors. These machines come in many configurations, ranging from small DIY desktop CNC aluminum routers to industrial equipment used in manufacturing plants.
Below, we’ve found five great machines for cutting aluminum. Since industry-grade CNC routers begin in the tens of thousands, we’ve focused on desktop options that meet a variety of different budgets. Let’s see who made the cut!
Whether you’re a CNC beginner, hobbyist, or small business owner looking for a machine that can handle commercial use, the SainSmart 3018-PROVer V2 is an excellent choice. With a body made of aluminum, this strong and stable router is priced at around $270.
“3018” is used across an entire range of CNC machines, but SainSmart is a name that many know and vouch for in the industry. Their entry-level CNC router’s PROVer version is based on open-source software and incorporates its own motion controller software: GRBL 1.1. Many users prefer to use open-source CAD software, which doesn’t come with the unit.
This SainSmart CNC router comes with manual control and can be upgraded with the laser module kit from SainSmart or other brands. For more details, you can watch a comprehensive review of the 3018-PROVer V2. There’s also SainSmart’s resource page and user manual available if you run into any issues.
The Lunyee 3018 Pro Max is a solid choice for anyone diving into the world of CNC machining, particularly for entry-level users interested in cutting and milling soft or non-ferrous metals. Its versatility makes it suitable for more advanced users as well, offering three distinct control systems: offline, manual, and computer-controlled. This flexibility ensures it can handle simple cutting, engraving, and design tasks with ease.
Built with an all-metal construction using reinforced aluminum profiles, the machine offers impressive durability, stability, and reliability. Additionally, its long Z-axis stroke of 80 mm sets it apart from standard 3018 machines, providing enhanced capability for deeper cuts and more complex projects.
Most reviews point out how easy it is to assemble and get started with, and makers who came across issues found that the supplier support saw to their needs.
The Quantum CNC Router Kit from BobsCNC, set in a sturdy laser-cut wooden frame, is another popular entry-level CNC router. It’s an excellent choice for creating signs, home decor projects, models, and much more, offering a surprisingly large cutting area for its price range.
The frame is rigid, providing stability for various projects. The included Makita RT0701C Variable Speed Router acts as the spindle, ensuring precision and reliability. Designed to run on GRBL1.1 firmware via an Arduino Uno, it also offers modern control capabilities.
While the manufacturer is transparent about its ability to cut aluminum, they caution that it isn’t recommended for this purpose, as explained in this video. The Quantum CNC is a router, not a mill, and the differences between these types of machines are significant.
MillRight is known for producing reliable CNC machines at a reasonable price. This particular machine excels at milling wood, plastic, foam, carbon fiber, circuit boards, and soft metals, making it a versatile tool for a wide range of projects.
Building on years of customer feedback from the successful original Carve King, the Carve King 2 features an all-aluminum frame for enhanced stability and precision. While the mount is provided, one downside is that the Makita router is not included, which might require an additional investment.
MillRight recommends using Autodesk Fusion for CAM, and hobbyists can access all necessary software for controlling the machine, including the MillRight CNC version of Universal Gcode Sender, which is free on their resources page. For added support, MillRight has an active user forum where you can seek help and share experiences with other users.
The Nomad 3 from Carbide 3D is a higher-end CNC machine that offers premium features for those willing to invest. Equipped with inductive homing switches and an enclosure for added protection, it also features an inductive safety door interlock, ensuring a safer working environment.
The machine comes with internal lighting, which enhances visibility during operation. Powered by a 130-W spindle motor capable of reaching a maximum of 24,000 RPM, it provides the precision and power needed for more demanding projects. Additionally, the Nomad 3 includes MeshCAM V8, proprietary CAM software, allowing for efficient design-to-production workflows.
