Investing in a CNC (Computer Numerical Control) machine is a significant decision for any business involved in manufacturing or machining. These machines have revolutionized the manufacturing industry by offering precision, efficiency, and versatility. However, selecting the right CNC machine for your business needs can be a complex process. That’s why we recommend consulting with our North American CNC machine builders.
To make an informed decision, consider the following key factors.
Before diving into the specifics of the different types of CNC machines, it’s essential to have a clear understanding of your business objectives.
Having well-defined objectives will help you narrow down your options and choose a CNC machining center that aligns with your specific needs.
CNC machines come in various types, each designed for specific tasks.
Select a CNC machining type that best matches the type of work your business performs. Additionally, consider the machine’s configuration, such as the number of axes (e.g., 3-axis, 4-axis, 5-axis), which determines the machine’s versatility and capability.
The physical size and capacity of the CNC machine are critical factors. You’ll need a machine with a workspace large enough to accommodate your workpieces comfortably. Consider not only the size of your current projects but also potential future needs. Ensure that the machine’s table size and travel distances meet your requirements.
Different CNC machines may require specific tooling and accessories for various tasks. Consider the availability and compatibility of tooling options for your chosen machine. This includes tool holders, cutting tools, clamps, and fixtures. Ensure that the machine you select can accommodate the necessary tooling and accessories for your applications.
The control system and software play a crucial role in CNC machining. Most machines use either proprietary control systems or industry-standard ones. The choice of control system can impact the ease of programming and the availability of technical support.
Moreover, the CAD/CAM software you use should be compatible with the machine’s control system. Ensure that your team is proficient in using the software or be prepared to invest in training.
Consider the availability of technical support and maintenance services for the CNC machine you choose. Machines require regular upkeep and occasional repairs. Opt for a machine from a reputable manufacturer or distributor that provides reliable customer support and has a network of service technicians.
Finally, your budget is a significant factor. While it’s essential to stay within your budget constraints, also consider the long-term return on investment. A more expensive machine with advanced features may lead to increased productivity and lower operating costs over time.
To make an informed decision, compare the initial purchase price, operating costs (including energy consumption and tooling), and potential revenue increase resulting from the machine’s capabilities.

Like many woodworkers, we can get bogged down in specs when we’re researching a new tool (or car or kitchen appliance). How many horsepower? What size bits can it use? What sort of steel is it made of? What’s the runtime on batteries? How fast does it go? Does it cook both breakfast and dinner?
Specs for CNC machines bring on a whole other level of complexity – feed rate, material removal rate, spindle power, torque, etc. Not to mention there’s a computer and software involved. That’s when we like to remind ourselves to take a step back and start at the beginning: What do you want to make? Why are you making it? How many do you plan to make? Who will be doing the making? That’s what Inventables did when they were making their new pro-level CNC machine: they developed a machine for customers that want to focus on their business rather than tinkering with the machine.
The X-Carve Pro was designed from the ground up to be easy to use, powerful, and a complete system to run a business. Inventables takes the guesswork out of CNCs by providing the machine (that goes from delivery to carving in under 2 hours), 3 years of their easy-to-use Easel Pro software, and best-in-class customer support. With their Easel software, if you can move a mouse around, you can start making things. It’s a self-contained system, so you know all the parts and pieces work together out of the box. (Of course, if you’re a seasoned CNC user with a CAD or CAM software program that you prefer, the X-Carve Pro works with that, too).
The CNC machine itself comes in two sizes, 4×2 and 4×4. The gantry is the same on both machines (a full 4′ of working width), so you can feed a 4×8′ sheet of material into the machine. This was one of the first things Inventables learned about many business CNC users: We all want capacity for a 4×8′ sheet but spend most of our time working on only a small section of that sheet. When you think about a 4×8 machine’s footprint, not only do you need space for the machine, but space to load/unload sheets and space to maneuver around the machine. The 4×2 and 4×4 sizes mean you can fit an X-Carve Pro (or more than one if you want to double or quadruple productivity) in most workshop spaces.
Both machines share the same gantry (the mechanism that moves the router up and down and around the bed). It provides a full 4′ wide cutting area, as well as 4″ of travel up and down (and 2′ or 4′ front to back). When you’re dealing with CNCs, you’re also keeping in mind resolution/accuracy. As far as CNCs go, you need to look at the total system. The gantry, drive system, stepper motors, and spindle all work together to determine what volume of material you can remove per time. The X-Carve Pro can cut 3/4″ deep groove in wood with 1/4″ bit up to 25 times faster than the original X-Carve. And with an accuracy of .001″. That material removal rate is pretty impressive – faster than you’d be able to safely do by hand on a router table or even with a dado stack in a table saw.
The gantry and movement system uses larger and more robust components when compared to other CNCs in this class, because it was designed to deliver incredible detail when V-Carving. The gantry is made from extruded aluminum with precision ground hardened steel linear guides and uses 292 oz/inch NEMA-23 motors to drive the 25mm ball screws (which control the movement of the gantry).
The actual tool doing the cutting is a 2HP air-cooled spindle. That means no separate pumps or water tanks. (some CNCs come with liquid cooled spindles that require extra gear).
This return on investment-focused approach to CNC machining – making sure the user experience is fantastic whether you’re cutting small intricate parts or turning sheet goods into furniture – truly pays off. Your time is valuable, and you don’t need specialized training to use it. The machine does exactly what you want it to do and the Inventables support team is right there with you to minimize downtime if issues come up. It just works.
