5 Common Types of CNC Machines

The most convenient way to get the most out of CNC machining is to understand the type you are using. There are various CNC machines designed to meet specific needs. The choice depends on the project you are working on. It is crucial to know that these are not average machines; they call for skills and trained professionals to achieve the right productivity.

Here are the most common types:


1. CNC Milling Machine

CNC mills are among the most popular CNC machines. They use computerized controls to cut different materials with excellent precision. The machines are designed to translate various programs using numbers and letters, moving the spindle in the right direction.

In most cases, CNC mills use a standard programming language known as G-code. This is a common language with CNC machines, which enables them to perform various functions according to user needs. CNC milling machines are larger than other tools that perform the same functions, allowing them to produce more materials.


2. CNC Lathe

Another common type of CNC machine industrial solution is the lathe. This is a machine used in cutting workpieces by rotation. They are the best solutions in situations that require precise cuts using different tools.

CNC lathe machines are more effective in terms of precision compared to manual tools. Most of them come with fewer axes than the milling machines discussed above, making them much smaller and more compact. But they have similar controls as the milling machines, which means they follow the same setup process.


3. A CNC Router

Have you ever used a handheld router to cut different materials? Well, a CNC router performs similar tasks only with the help of computerized operations. They are used to cut steel, wood, aluminum, composites, and many other materials.

Like the CNC mill, a router can effectively translate computer numerical controls and routing tool paths for the machine's proper functioning. With this machine, you can reduce waste and increase productivity as they work much faster. However, you may not get the right output without the proper setup.


4. CNC Plasma Cutter

As the name suggests, CNC plasma cutters are machines used to cut materials too, but they do so using a high-powered plasma torch. The electronically ionized gas is computer powered to offer the highest level of precision. Its operation is not different from a handheld, gas-powered plasma cutter.

The plasma torch passes through the material, melting it to create high precision. One of the requirements for using a CNC plasma cutter is that the material must be electronically conductive. Thus, you can use it to cut steel, aluminum, brass, and copper with a wide variety of production capabilities.


5. CNC Electrical Discharge Machines (EDM)

Another common and very effective type of CNC tool is the electric discharge machine. The EDM applies highly controlled electrical sparks, manipulating the material to create the perfect shape. Sometimes this machine is called a spark eroding, die sinking, or sparks machining.

Using these machines is quite simple. You place the component under the electrode wire and then program the machine to emit an electrical discharge of the wire, producing intense heat. The heat melts with material with liquid, shaping it into place. If you want to create high-precision holes, this is the machine you want to use. It can also make slots, tapered or angled features, and many other complex shapes.


CNC Machine Optimization Setup and Tips


CNC Machine Setup


So, the first step to setting up your machine properly is understanding the different types. Luckily, all machines use almost the same operating principle as they rely on computerized setups. Thus, the setup strategies for optimum performance apply to all of them.

This is a beginner's guide to getting the best out of your machine:


CNC Machine Setup Checklist

The next crucial step to setting up CNC systems is finding preparing the machine properly and ensuring everything is in perfect position. Here are things to check before starting:


Get the setup set

Never start your CNC setup process until you have all the fixtures, tools, and materials near your CNC system. This makes your work more efficient, saving you time. If you don't have enough space near the machine, consider setting aside a specific place where you will operate from. However, be sure not to create a too complex setup process.



Your CNC machine setup checklist must include a proper understanding of your CNC systems. Some machine, like the ones with linear drive systems, is modern and extremely effective. But the biggest downside is that they are super sensitive and expensive. You should use these machines in a better machining environment. But the best approach is to get a modern machine with better overall mechanisms and quality parts.


Ensure proper temperature setup

Fluctuating temperatures in your workshop can adversely affect the machine's tolerance. Therefore, check that clean air is constantly supplied into your workshop and machine. You can do this by placing the air compressor at an optimum proximity to the machine.


Check the feeds and speed

Surface finish quality is extremely delicate and crucial. Feeds and speeds during the machining process can affect the quality of the part. 

They also affect the machine vibrations and create unbalanced tooling. Avoid any worn-out tools or those already at their limit, as they also influence the external sources of your machine.


Check the right cutting tool

Do you have the right cutting tools? And have you set them on the recommended cutting settings? This step is crucial if you want to get a high-quality surface and finishing. You need to have an experienced operator who will know the required tools.


Check the coolant

Always keep an eye on the coolant, ensuring it's always the right amount. Check that the mixture used is suitable to ensure proper continuous and effective machine operation.


Check the lubrication

Regular checkup and using the right lubricant is extremely important. Look at the machine manuals for the recommended oil types focusing on the brand and viscosity. This will keep your machine in the best operating conditions for the longest time. Avoid cheap and poor-quality lubricants.


Check the spindle load

Overheating is one of the biggest issues with CNC machining. It happens when you don't keep the machine within the spindle load recommendations. Get new filters from time to time and ensure the compressed air is clean to avoid contamination.


The entry door

Many people get surprised when they don't check the clearance at the entry of their workshop doors. The machine will arrive but may not fit through it, forcing you to cut more space, which can be a big headache. So, ensure the door is properly sized.



Do check and maintain high workplace safety. Remove any hazards and potential accident areas in your workshop. Simple things like loose connectors, screws, or parts not mounted properly can potentially cause accidents and must be checked.


The Process

Lots of personalized content and ads exist on the internet about CNC setups. Some use cookies and data to ensure you have every information when you need it. Use them to learn the best setup methods.

Here are some of the crucial things to check to optimize your CNC machine setup.


Get the right machine

The mechanical design of your machine is extremely crucial. The part's complexity and the number of sides your machine can work on affect how fast, precise, and accurate the outcome will be. One of the most recommended ways of getting such features is upgrading to a five-axis machine.  

Three-axis machines are good, but they may waste time as they require extra setups in production time. A machine that uses more axes speeds up production and makes your work much easier. 

But if you already have a three-axis machine, you can add a two-axis table, creating a more efficient working environment. This machine CNC optimization strategy always works when you have a bigger project.


Proper assembly

The most complex CNC machine industrial projects take more time and require great expertise. For instance, the Tool Length Offsets must be correct to their tools, with accuracy for correct cutting. Thus, you need to take time and get the assembly process done well. You should hire a professional operator who understands the parts perfectly to avoid any miscalculations.

Many experts recommend the use of tool presenters for more precision. Proper add-ones will measure your tool's accuracy, quickly giving you feedback for the right action – they must work in under a minute. On the other hand, a mechanism applying a touch probe will take over an hour to set up 15 tools for any job. Presenters show the exact tool position, assuring the most accurate results.

A precision setting is not the only thing to check here, though. You also have to use proper work-holding devices to ensure the tool does not fall or slip in the middle of the project. Electro-permanent magnets have been used for many years to offer this service.


Improving the machining process

Every mechanist wants to get the most out of their CNC machine industrial project by optimizing the machine's operation. So, you can easily get more from the process by setting the machines properly and ensuring a proper workplace environment.

Here are some tips to get this right:

Organization in your workplace. Your workers need to understand how to operate the machines. Also, frequently upgrade your software and hardware to achieve the highest precision and improve the process.

Change our machine's travel guidance system. CNC machines produce more accurate results based on how it works around roll, pitch, and yaw movements.

Properly support the machine bed. If the bed is properly set, it supports the moving parts effectively, ensuring the accuracy of your machine. The interaction between the bed and the foundation greatly affects the results' accuracy.

In other words, create a work environment that assures high efficiency and effectiveness. You can set up your machine to make it easy for the machine to run smoothly. Optimizing CNC machine setup will not be effective if the working atmosphere is not optimum.


Check and wear and tear

Tools work less efficiently when they start wearing and tearing, but they last longer, working efficiently when you keep them in check. Therefore, ensure dull and worn tools are replaced immediately to avoid details in completing your work. You can avoid this using several ways, including:

Avoid equipment failure. Unplanned downtime due to equipment failure may cost more than planned work stoppage.

Keep your tools properly maintained, and you can avoid such surprises.

Have a predictive maintenance schedule with proper preventive maintenance.

Regularly examine your tools, filter, and spindles.

Choose the highest quality tools wherever possible. Soft tools wear much faster than harder ones.

Your tools' quality and efficiency are directly linked to proper maintenance. This allows you to check for wear and tear, replacing any part that starts showing issues.


Use high-precision made-to-order parts

You will spend a lot of time and money to achieve top precision and repeatability with your CNC machine setup. Upgrades can be too high and ultra-high accuracy and precision hard, which is why not every machine shop may have what you need. Some companies outsource their orders for high-precision parts, ensuring the best results and performance.

Using made-to-order parts allows you to set your machine in a way that does not compromise its operations but delivers the highest quality levels. You can get these parts from specialty shops to use them on specific projects for high efficiency and accuracy.

Third-party shops may save you some money when ordering parts for specific tasks, but made-to-order parts reduce wear and tear. Your significant investment in these parts pays more in the long run. It is a smart move for your business.



Efficiency and accuracy are, without a doubt, crucial in the CNC machining industry. You need to ensure the parts are designed to meet their specific user needs and done quickly. This can only happen if you set up CNC machine properly. Factors like proper tool length offset, cutter radius compensation, and the effectiveness of the load tools much be checked, depending on your settings.
