The Best Aluminum Milling CNC Machines for Hobbyists

Aluminum is the most abundant metal on the planet but finding the best aluminum milling CNC machines is like scavenging through a desert for mineral water.


Not to say there aren’t any great aluminum milling CNC machines out there.


Indeed, there are.


But if you are not careful, you might end up getting the wrong product.


Let us explain.


Aluminum is one of the most versatile metals that is used across a range of industries.


Whether we talk about automobile manufacturing or aerospace designing, aluminum’s strength and relatively lower weight make it one of the most used metals in the designing and production industries.


If you are a hobbyist machinist, you know aluminum is pretty great to work with. 


It chips easily and is convenient to shape up. 


Aluminum is 3x to 4x easier to machine than iron and steel.


That’s probably why most hobbyists machinists tend to work with aluminum. 


It allows newbie machinists to hone their machining skills and get started with CNC machining.


But when it comes to CNC machining, the cost adds up.


Whether it is aluminum or steel, CNC machining is a costly endeavor. 


Using CNC machines, it takes time, money, and resources to carve something out of a workpiece. 


And chiefly because of the cost, the idea of CNC machining gets a bit out of hand for most hobbyist machinists.


But, don’t worry.


We have got you covered.


We are compiling a list of the best CNC mills for aluminum that don’t burn a hole in your pocket.


So, without further ado, let’s get into it:

The Cenoz 3018 Pro is one of the most complete aluminum milling CNC machines.


If you don’t want to go with the SainSmart 3018 PROVer and are looking for an alternative, the Cenoz 3018 Pro is right up your alley.


Unlike the PROVer, the Cenoz 3018 Pro is an entry-level CNC router.


The build and functionalities of the Cenoz 3018 Pro make it a perfect machine for milling soft and non-ferrous materials. 


The router has recently seen an upgrade. Now, it comes with a new control board, the latest GBRL 3 axis control, more power, more precision, an integrated driver chip, and a fixed heat sink.


The machine comes with all the assembly details in the package, which makes the assembly easier. It only takes around 20 minutes to get the machine up and running. 


The GBRL three-axis control can run on Windows XP, Windows 7, Windows 8, and Linus, making it convenient for everyone to access this machine.


It also comes with an external controller, allowing you to manually control the three axes without connecting them with a computer and downloading files.


The Cenoz 3018 Pro can perfectly cut through all types of plastic, aluminum, wood, acrylics, PVCs, and PBCs. 


The best about this mini router is that it is easy to access and doesn’t have any hyperbolic learning curve.


The Cenoz 3018 Pro is also easily upgradeable. 


You can simply add the laser kit module as a drop-in upgrade to the machine. 


You can also add a Y-axis extension and expand your work area if you find the work area of the Cenoz 3018 too small.


Not to mention, the Cenoz 3018 Pro also comes with open-source software support and additional training guides and tutorials to get you started.


Vevor 3020 

The Vevor 3020 is one of the most robust aluminum milling CNC machines.


The Vevor 3020 is known for its sturdy structure and powerful machining. 


It can easily cut through aluminum, plastic, acrylics, PCBs, PVCs, wood, and other non-ferrous materials.


The machine comes with an aluminum worktable made of industry-standard 6061 aluminum alloy and 6063 aluminum. 


Moreover, there is also an aluminum backing plate, which adds up to the robustness of the machine.


Suitable for both enthusiasts and amateurs, the Vevor 3020 offers a well-designed axis, high efficiency, precise control, and superior working area.


The solid build of the machine makes it one of the most efficient CNC machines out there. It cuts through everything you throw at it (as long as it is non-ferrous material) with little to no noise.


If you like your CNC machines with elaborate controls, the Vevor 3020’s controller won’t disappoint you.


It comes with a controller with a built-in transformer, making for a stable power supply throughout the control unit over a long and continuous period. 


Each of the axes on the Vevor 3020 is equipped with 57 two-phase stepper motors for more effortless movements. 


The stepper motors are also connected by external coupling, helping provide high-torque cutting. 


It also comes with a USB flash drive using which you can connect the machine directly to a computer instead of relying on an optical disc drive.


Shapeoko 4 

The Shapeoko 4 is one of the most approved aluminum milling CNC machines.


Launched in 2021, the Shapeoko by Carbide 3D is the latest addition to the affordable CNC mill lineup. 


It is the successor to the popular Shapeoko 3, which was already an excellent CNC mill to begin with.
