When it comes to buying a CNC machine, one of the most important things is to make sure you choose a machine that’s the right size for what you want to do. From small desktop routers to large industrial machines, there are plenty of sizes to choose from, one is 2×4. So, is a 2×4 CNC router kit right for you?
This guide is designed to help you answer that question. We explain what 2×4 CNC machines are, what applications they’re best suited for, and what benefits they have over other machines. Then, we review some of the best 2×4 CNC routers that you can buy today.
What is a 2×4 CNC Router?
A 2×4 CNC router is simply a router that measures 2ft by 4ft, meaning it’s 2ft wide and 4ft long. CNC machines come in a wide range of different sizes, and 2×4 is a mid-to-large size router. While it’s smaller than lots of industrial machines, it’s also a fair bit bigger than many hobbyist machines.
Other common large-scale CNC router sizes include:
And some common small CNC router sizes include:
For example, many CNC beginners and casual hobbyists go for small benchtop machines like 3018 CNC routers, which have a 300 x 180 mm work area. These are affordable machines that can be picked up for a few hundred dollars, and are best for small projects.
In contrast, a 2×4 router gives you a lot more room to work with, meaning you can work on larger projects. For example, if you’re in the business of making signs or advertisement boards, a 2×4 CNC router is probably be going to more of more use to you than a smaller 3018 or 6040 CNC machine.
Sign making is just one of many uses of 2×4 CNC routers, though. Their relatively large size means they’re also commonly used in carpentry for the making of things like furniture and cabinets. Other uses include mold making, stone processing, metal fabrication, cutting plate production and the making of indoor decorations.
2×4 isn’t a hugely common size when it comes to CNC routers. There are a few machines out there, but you don’t have as much choice as you do with other size routers. Plus, a 2×4 CNC router kit will set you back several thousand dollars, so it’s important to make sure you need a definitely 2×4 instead of a different size machine before you splash out.
Of course, you may find you need a larger working space, such as 4ft x 4ft. We’ll take a look at some alternative size CNC machines after we’ve reviewed the best 2×4 models in case you want to explore some different options
