Milling metals is a general term defining methods of processing various materials, including metals, wood, and plastics. The removal of chips from the raw material is done either mechanically or manually. This controlled and complex method of metal processing is often used. One of the most well-known processes of metal cutting processing is milling. Milling uses rotating tools to remove material. Metal is milled in various ways, sometimes with inserts made of sintered carbides. Milling is done using computer-controlled machines, also known as CNC. After milling, the material must cool down. The condition for milling metal is the use of coolant.
What is CNC milling?
CNC is a computer-controlled machine that processes semi-finished products or materials, such as metal. CNC stands for Computer Numerical Control and is widely used not only in the metal industry but also in other fields of production. Examples include the plastics, wood, and glass industries. The advantage of CNC milling is that the machine is pre-programmed, making certain operations easily repeatable. This allows for the processing of large amounts of material in exactly the same way. Moreover, there is the possibility of performing highly precise milling based on previously prepared designs. Machining projects, also called CAD projects, are transferred from the computer to the milling machine. In this way, the machine knows what to do.
How does phrasing work?
CNC metal milling is a process of removing material from a workpiece using computer-controlled machining. This process can be used to create parts with complex shapes and features, and is also often used for prototyping and small-scale part production. The first step in CNC metal milling is to create a computer model of the desired part. The model can be created using CAD software or a 3D scanner. Once the model is complete, it is converted into tool paths that instruct the CNC machine on how to move to remove material from the workpiece. The next step is setting up the CNC machine. The machine must be equipped with the appropriate cutting tools and holders, and the workpiece must be securely mounted on the machine. Once everything is in place, the CNC machine can begin milling the part. During machining, the cutting tool is in constant motion, removing small amounts of material from the workpiece. The speed and precision of the CNC machine determine how quickly the desired shape can be achieved. After milling is complete, the part is often subjected to finishing processes using traditional methods such as grinding or polishing. CNC metal milling is a versatile manufacturing process that can be used to create parts with complex shapes and features. It is often used for prototyping and small-volume part production.
CNC metal milling is a process in which a computer-controlled cutting tool removes material from the workpiece to achieve the desired shape. The cutting tool is mounted on a spindle and moves in three axes (X, Y, and Z) to achieve the desired effect. This type of machining is often used to create complex shapes or machine parts with tight tolerances. It can also be used for the quick and efficient production of a large number of parts. The first step in CNC metal machining is to create a computer model of the desired shape. The model can be created using CAD software or manually. Once the model is ready, it is converted into a set of instructions for the CNC machine. The next step is to load the appropriate tools into the machine. These tools may include end mills, ball end mills, reamers, and taps. The choice of tool will depend on the material being machined and the desired outcome. After loading the tool, the CNC machine is programmed to follow the instructions of the computer model. The machine then moves the cutting tool in the required direction to achieve the desired shape. After the shape is created, the workpiece is removed from the machine and checked for quality. If everything is in order, the part is ready for use. If there is any problem with the part, it can be sent back through the CNC machine for adjustment. CNC metal milling is a precise process that can produce high-quality parts. It is commonly used in the aerospace, medical, and automotive industries. In woodworking, a wood planer is often used when intending to cut various wood profiles for the purpose of hollowing out holes or making decorative grooves on the edges. Thanks to the ability to mount different types of knives, these tools can perform a variety of tasks on both hard and soft wood. Wood routers are divided into three types: surface routers (including plunge and stationary routers), edge routers, and table routers. Each of them will vary depending on their purpose and the type of wood used. In this way, depending on these factors, they will take power, speed, weight, sleeve diameter, or cutting depth. Do you know which of the three existing types of routers is most commonly used? This article will explain everything.
What are the types of wood milling machines?
As mentioned earlier, there are end mills, edge mills, and table mills. To help you distinguish them, I will briefly describe each of them.
Surface milling machine
Compared to the other two models, the end mill is very strong and heavy, though not as heavy as the table mill. Moreover, they are supplied with cables or batteries and are in the medium or high price range. Its design is intended to use both hands at all times, facilitating more precise manipulations, and among the various functions it performs, the following stand out: smoothing or rounding edges and making grooves. This type includes plunge routers and fixed-base routers. The latter cannot penetrate the wood in a resting position, as they do not have springs or guides.
Edge milling machine
Although edge milling machines are as versatile as surface milling machines, they are most often used for trimming boards and slats. Moreover, they are slightly less efficient than the former, although they are lighter and therefore more convenient to use. To such an extent that sometimes they can be operated with one hand. In this case, there are also battery or network ones, which are priced between surface and table mills.
Table milling machine
When it comes to table mills, I can say that they are the heaviest and most powerful of all mills. These corded cables are significantly more expensive than the other two. This is often required when many parts need to be milled in the same way. Just like with planer mills, there are two types here: manual and numerically controlled, i.e. CNC. The main difference is that CNC machines are automated.

What aspects should you consider when using a wood planer?
- Balance
Just like with any other tool, weight affects the operation of the machine. The lighter it is, the easier it is to maneuver. However, it is true that the heavier the machine, the more stable it will be. A milling machine weighing 2-4 kg is most commonly used, especially for jobs that do not require milling many elements.
- Chuck diameter
It depends on the type of device connected. Typically, the shank has a diameter of 6 or 8 mm, but it can even be 12 mm or more. The largest is 12mm and requires a more powerful router.
- Cutting depth
Depending on the router, the cutting depth can range from 30 to 60 mm. Indeed, the deeper you go, the more powerful tools you need.
- Accessories
The accessories needed for a milling machine include: a milling cutter, a spindle for holding the cutter, a vacuum cleaner (if required), guides for making specific shapes or straight cuts, and an auxiliary guide for precise path determination.
- Power and speed
Both of these factors are closely related to the type of wood used. Most routers have a speed regulator, which allows you to adjust it as needed. Unlike other materials, such as plastics, which should be cut at a low speed, wood should be cut at a high speed to avoid chipping.
Which of all types of wood routers is most commonly used in the timber industry?
At the beginning of this article, I asked you a question. Do you know which are the most frequently used wood routers in wood processing? At this point, I will tell you that out of all the types I have taught you, the most commonly used are end mills. Particularly captivating. This is because these tools are easy to use, easy to transport, do not take up much space, and are inexpensive. In addition, they have a lot of power for their size and speed regulators. They offer an ideal balance between functionality, quality, space, price, and equipment. Especially when we process small amounts of wood.
Wood milling on a CNC router
The tried and tested High-Z/T CNC milling machine can process even hard wood, such as oak, beech, and ebony, with great precision. In the case of precise wood processing, the machine's stability in all axes is crucial, as the resistance of hard wood exerts a large reaction force on the entire machine structure. The High-Z T-series ball screws provide increased precision and speed of the milling process without wearing out forces.
What type of wood processing requires a CNC milling machine?
Manual milling of complex shapes with traditional tools quickly reaches its limits, for example, milling beveled recesses, rounded corners, or finishing contours for inscriptions, patterns, or images. By processing calculated milling paths with assigned feed speeds and entry depths, CNC milling machines can perform these 2D and 3D wood processing tasks more accurately and faster than a skilled worker.
CNC wood processing services instead of traditional tools
This is a fast, precise, and economical production. More and more craftsmen, journeymen, and hobbyists are using CNC milling machines for processing wooden products that were previously made by hand. The machines are faster, more accurate, and less prone to errors. The operator can use his working time more efficiently, as he can perform other tasks during production. It even increases profits, as wood is used more efficiently due to less waste material.
Example: Using CNC wood processing for furniture production
Furniture production is a good example of time savings that can be achieved with a CNC milling machine. A carpenter has to mill grooves at the front and sides of the wardrobe to insert partitions and back panels, as well as small holes for connecting elements and large round recesses to hide hinges. CNC services can be used not only for steel processing. CNC cutting of plywood, as well as broadly understood wood processing using this machine is practical. A CNC machine, or laser cutting, will also process wood-based materials. The CNC processing process can be used for decorative elements made of plastic and natural materials (e.g. chipboard). Full automation will result in ready-made elements in a short time.
