A Buyer’s Guide to Benchtop CNC Machines
As CNC machines have grown in capability and popularity, they’re finding their way into more and more home shops. With small footprints and relatively low price tags, benchtop CNCs—essentially robotic routers—provide a good way to dip your toe into the “tech” side of woodworking. If you’re intrigued by the idea, but don’t know a gantry from a spindle, we’ll help you understand the important things to look for in a CNC.
Understanding Benchtop CNC Machines
Benchtop CNC machines are compact, versatile tools designed for various applications, including woodworking, metalworking, and engraving. They are ideal for hobbyists and small business owners who need precision without the space requirements of larger machines.
Key Technical Features
When evaluating benchtop CNC routers, consider the following technical features:
| Feature | Description |
|---|---|
| Work Area | The maximum size of the material that can be processed. |
| Spindle Type | Options include routers and dedicated spindles, affecting performance. |
| Drive System | Common types are belt drive, lead screw, and ball screw, impacting speed and accuracy. |
| Motor Type | Stepper motors are typical, but servo motors offer better precision. |
| Software Compatibility | Ensure the machine works with your preferred design software. |
| Dust Collection | Integrated systems help maintain a clean workspace. |
Types of Benchtop CNC Machines
Benchtop CNC machines come in various types, each suited for different tasks. Here’s a comparison of the most common types:
| Type | Best For | Key Features |
|---|---|---|
| CNC Routers | Woodworking and soft materials | High-speed cutting, versatile tool options |
| CNC Mills | Metalworking | Precision machining, often heavier and more rigid |
| Laser Cutters | Engraving and cutting | High precision, ideal for detailed designs |
| 3D Printers | Prototyping and modeling | Layer-by-layer construction, versatile materials |
Choosing the Right Benchtop CNC Machine
Budget Considerations
Benchtop CNC units sell from about $1,500 to $6,000, with many variables affecting pricing. As with many tool purchases, first decide not only how much you can spend but also how much you should spend. Remember this adage: “Buy the best and you’ll only cry once.” Precision, tight tolerances, and durability typically add cost. A low-cost machine may not give you the performance you need, adding frustration and buyer’s regret.
Workpiece Capacity
Like any machine, a CNC unit has a given workpiece capacity, called its “envelope,” expressed as the maximum travel in the X, Y, and Z axes. Understanding how you plan to use your CNC determines what capacities the machine needs. For example, if you plan to carve small signs, a smaller envelope may suffice, but larger projects will require a more extensive work area.
Future Growth
Anticipating how you’ll use your CNC in the future is crucial. Today’s simple work may grow into projects that require tighter tolerances or larger pieces. Some benchtop machines can do work in a fourth axis: rotation, allowing you to create almost any round, cylindrical, or spiral piece, such as table legs or chess pieces.
Power and Space Requirements
As you consider adding a CNC to your shop, think about how well your shop will accommodate this new tool. Benchtop CNCs come prewired for either 110 or 220 volts, with varying amperage requirements. Make sure you have a power supply that meets or exceeds the needs of the machine. Additionally, consider the total footprint, portability, and dust collection needs.
