The Best CNC Machines
Computer numerical control machines, or CNCs for short, have revolutionized the manufacturing world in recent decades. And these days, you can try your hand at the craft without calling on a professional workshop, thanks to the wide availability of affordable and versatile CNC machines for personal use. We've taken stock of some of the finest out there and highlighted a range of options for beginners and experienced users alike.
What to Look For
Whether or not you’re a total newcomer to the world of computer-aided manufacturing, there are a few things to consider as you compare different machines. Some CNC machines will arrive mostly assembled, whereas others require extensive assembly. Some folks may not want to go through that laborious process, while others might prefer it so that they can better understand how the machine works. It’s also important to consider your CAD software of choice, as not all machines boast universal compatibility. Some might omit the inclusion of an offline controller entirely, meaning you’ll have to invest in this yourself or rely on a computer for operation. With all that in mind, we rounded up a few of our favorites. For example, the affordable and easy-to-use Genmitsu 3018-PRO stole the top spot on our list. Though its downscaled cutting area won’t allow you to work with large materials, the clear documentation and simple interface design make it easier to user than most CNC machines. If you’re a more experienced CNC operator looking for a challenge, the BobsCNC Quantum offers a large cutting area at a great price, though this complex beast comes entirely disassembled. Read on below to discover the rest of our favorites.

BobsCNC Quantum Router Kit
Grand design
Equipped with a mammoth 24″ x 24″ cutting area, the Quantum router kit from BobsCNC won’t hold you back when tackling the largest designs. Novices might be daunted by the lengthy assembly process required to get this workhorse up and running, which includes the complete construction of the plywood frame and the application of a polyurethane coating. By investing the energy in its construction, however, you’ll familiarise yourself with an elegantly engineered and highly capable machine that could last for years to come.
Pros:
- Significantly cheaper than similar CNCs that arrive fully assembled
- Self-squaring gantry is easy to calibrate
- Though the assembly takes a while, you may appreciate the knowledge you pick up by putting the machine together yourself
Cons:
- Difficult to replace the router if it fails
Genmitsu PROVerXL 4030 CNC Machine
Hard as nails
While CNCs often find a home in woodworking applications, with the right module, you could enjoy the same diligent precision while working with metal and other hard materials. The PROVerXL 4030 incorporates the same user-friendly design philosophy of Genmitsu’s smaller machines in a brawnier, upscaled design. With powerful NEMA23 motors offering significantly more torque than NEMA17s, this beauty’s routing head can effortlessly whittle a range of metals.
Pros:
- Accuracy up to 0.1 millimeter
- Durable C-beam structure
- Adapter included for DeWalt DWP611
Cons:
- Doesn’t accept RPM G-Code commands
Frequently Asked Questions
What materials can I cut and engrave with my CNC machine?
Equipped with appropriate bits and armed with the correct settings, a CNC machine can work with most materials. Though they’re typically used for woodworking, you could also achieve results on acrylic, carbon fiber, and even soft aluminum. The densest materials will require more motor power as well as harder bits, so if you’re planning on working mostly with metal, be sure to choose an appropriate design.
What software do I need to run a CNC machine?
If you’re buying your first CNC machine, bear in mind that you’ll need a computer to get started with making your first designs. First and foremost, you’ll need to choose which CAD software to create your designs with. Most CNC machines offer a wide range of compatibility, so if you’re already experienced with a specific software, you can probably use this to your advantage. If the choice of software is a dealbreaker for you, be sure to check for compatibility issues in the documentation before you buy.
