Given how expensive most CNC machines are, it’s vital that you know exactly what you need before you make a purchase.
Even if you get the right type of CNC machine, a low-quality pick can result in lower manufacturing efficiency, needless material costs, and a lot of frustration for you or your employees.
With that in mind, here are some of the most important things to consider when selecting your CNC device.
To even begin to look for a CNC machine, you should ask yourself what sort of application you need it for.
Once you define your needs and wants, choose the size of your CNC machine and its cycle time.
Also, take into account the maintenance costs and the price of any spare parts.
When choosing your CNC machine, make sure that the device manufacturer has excellent customer support.
After all, you wouldn’t want to get a defective product and be unable to do anything about it.
Finally, remember that more expensive doesn’t automatically mean better. Read the advice below and learn all there is to selecting the right CNC device!
Choose the Right Application
CNC machines are great at increasing the productivity and accuracy of your manufacturing process but only in the right application.
It’s important to think about what you want to use your CNC machine for. For example, do you need a vertical or horizontal CNC machine?
If you’re aiming for absolute precision and constantly following the surface roughness chart, then the CNC mill is probably a better bet than a CNC router.
On the other hand, if you’re just looking to cut a variety of materials quickly and easily, CNC routers are the way to go – they’re usually cheaper both in the purchase and operating costs.
Also, make sure that the CNC machine of your choice works with your preferred material.
For example, some CNC machines are better at working with softer materials like wood while others can deal with harder elements such as titanium, aluminum, and steel.
Consider the Size of Your CNC Machine
The size will also play an important role when choosing the right CNC machine model.
Say you find a great device with all the features you’re looking for. Still, it won’t do you any good if it doesn’t fit in your factory or workshop.
When deciding on your CNC machine’s size, think about the available space and the dimensions of your average workpiece.
Good CNC machine manufacturers will offer a variety of sizes and shapes. This way, you can choose a machine that suits your needs perfectly.
However, make sure to also think about the machine’s weight and its ability to move.
If you need to regularly transport it to different locations, you want a device that is light and compact enough to be easily placed on a truck bed or carried by a few people.
Keep in mind that big doesn’t always mean better.
In fact, some projects might require a smaller machine that offers more flexibility and precision. Also, the bigger your machine is, the more power it will consume.
Pay Attention to Cycle Time
Cycle time is the amount of time needed to complete one full cycle of a CNC machine’s operation.
This includes all the steps, from the device’s initialization to the loading of the next workpiece and starting a new cycle.
The ideal cycle time depends on your manufacturing needs. However, in general, the shorter the cycle time, the better.
Short cycle times are especially important for large companies that work with high volumes of products or small parts.
After all, the faster your CNC machine is, the more orders you can get done.
This means that you’ll be able to produce more goods and increase your profits.
However, if the CNC machine is for your personal needs only (perhaps you’re a hobbyist woodworker or just love tinkering with tech in your workshop) there might be no need to pay additional thousands for a slightly better machining speed.
Consider the Maintenance and Spare Parts Costs
Another factor to consider before you get your CNC machine is maintenance costs.
It’s only natural that even the best CNC machines will eventually need repairs and replacement parts.
However, some machines might be more prone to breakdowns than others.
As such, it might be a good idea to read the reviews or discuss your choice with more experienced users on Internet forums and Facebook groups.
This way, you’ll be able to find out if the CNC machine of your choice is easy to repair or if spare parts are widely available at reasonable prices.
Of course, this doesn’t mean that you should completely avoid a machine with a few negative comments.
Selecting the right CNC machine can be a daunting task. With so many different models and manufacturers to choose from, it’s hard to know where to start.
However, as long as you keep in mind what you want to use it for and how much money you’re willing to spend on it, you should be able to find the right CNC machine for your needs.
Ultimately, the best way to find the right device for your project is to analyze your needs and consider the advice provided above.
Ultimately, it’s better to over-research than to buy a CNC machine that doesn’t suit your needs perfectly! Good luck!
