What is a Wood CNC Machine? How Does It Work?
Before we dive into the details of wood CNC machines, it is a must to understand what CNC is, why they are called CNC machines, and what kinds of machines people consider to be CNC.
CNC stands for Computerized Numerical Control. It is a kind of control established with the help of preprogrammed codes and software to control the machine. It is a numerical control, so it controls every part of the machine and its movement similar to our brain, which controls the organs and body parts.
CNC is an advanced control that is done through G-code, which is a special programming language. It makes the machine automated and processes the object according to the given instructions. In the past few decades, CNC has gone through significant evolution and improvement. Now, it is quite precise and accurate.
Many industries rely on CNC because it offers them the results needed in the shortest time possible and with minimal human involvement. It is quite efficient and productive for medium to high-volume production. It also reduces the labor requirement, so overall, the cost of production is reduced.
The machines that are controlled by CNC are known as CNC machines. It could be anything, such as CNC lasers, CNC grinders, CNC lathes, CNC routers, and CNC milling machines. These machines have a dedicated control that improves speed, accuracy, automation, and various other factors.
Wood projects made by CNC laser machines
You might have seen old-schooled lathes, routers, grinders, and other machines. They need an operator that constantly operates the machines and controls the movements of the parts. CNC machines have completely changed the usage of these machines. Through a control unit, preprogrammed code, software, and other requirements, the machine is controlled.
Wood CNC machines are used for subtractive manufacturing because all these machines remove the material from the surface. Whether it is a laser machine, lathe, or router, all these remove the material from the object. The user provides a design, CAD file, or any other compatible version through the software. Then, the machine follows the instructions and turns the wood into the desired shape, size, or cut.
What Are the Benefits of Using CNC Machines for Woodworking?
Automation
The first benefit of using CNC machines for woodworking is automation. The machinists have to provide the design through the software and fill in all the required settings and details. Once the machine is started, everything is done automatically. There is no need to operate the machine or do anything. The machine follows whatever instructions are provided, and it stops after completing the job.
Time-saving
Woood CNC machines are quite fast because of automation and minimal human involvement. The machines work at an incredible pace and do the job in no time. With that being said, these can increase productivity, and you can process high volumes. This is the reason industries and large-scale businesses prefer CNC machines. These save time and improve efficiency.
High Accuracy
If there is any human involvement in creating a product, there are chances of errors. You cannot even make identical products every time. But CNC and other automated machines offer high accuracy. You won’t see an error of a fraction of a millimeter. If you make several pieces using the machine, all will be identical. Thus, if accuracy is the main concern, there is nothing better than automated CNC machines.
Safety
CNC machines are much safer than traditional machines. The reason behind it is automation. The operator only has to provide the instructions through the software, and the machine does the job. So, the operator is safer. In contrast, a traditional lathe operator is exposed to various hazards. He can even cut his fingers and injure himself.
Reduced Cost
CNC reduces the overall production cost. First of all, it reduces the number of persons required to operate the machine, which means less manpower is needed. Secondly, it works at a fast pace and increases productivity, which ultimately reduces the price of production. It can also help in scaling the business.
What are the Types of Wood CNC Machines?
CNC Wood Router
A CNC wood router contains a sharp rotating blade that cuts and engraves wood and other materials. It removes the wood from the surface and gives it the desired shape and engraved texture.
The part of the machine that holds the rotating blade is called Spindle. It rotates the blade at different speeds according to the requirements. The material that needs to be processed is placed on the working bed, and then the machine is started.
The machine moves the spindle on X, Y, and Z axes to control the movement of the blade and turn the object into the desired product. This movement is done with the help of a drive system that contains several powerful motors. The spindle is moved precisely to ensure accuracy during the subtractive manufacturing process.
The whole machine is controlled by CNC. It requires a design for the task, so a CAD designer is needed. This design is communicated to the machine through the software. The software or preprogrammed code reads the design or the CAD file, and then it provides the G-code to the CNC. Finally, CNC commands the drive system to move the spindle in the desired direction. It controls every part of the machine as needed to achieve the results.
People often get confused between a CNC router and a CNC laser. They often think that both can do engraving and cutting, so they are the same. However, there is a massive difference between these two CNC machines.
A CNC router creates physical contact with the object and removes the material from the surface by using a sharp blade. But a laser machine does not make physical contact. It burns wood and offers perfect cuts using a laser beam. The engraving gives an appealing contrast because of the burning.
CNC Wood Milling Machine
A CNC wood milling machine is also used for cutting and engraving materials. It can turn the material into the desired shape. It also contains a rotating end mill that cuts the materials similar to a drill bit but it works in all directions.
This machine also has a spindle that holds the end mill. The driver system moves the spindle in the required directions to get the desired results. The design is provided to the software through a CAD file, which is then translated into G-code.
A CNC milling seems to be similar to a CNC router, but there are some differences. A milling machine is specifically designed for harder materials, such as metals; however, it can also work on wood and acrylic. In contrast, a router is only suitable for soft materials, such as wood. The compatibility with materials is a major difference between these machines. Secondly, the speed of the end mill in milling machines is slower, but the torque is quite high. This is the reason it can cut hard materials easily. Thus, the whole process takes more time. The working area or bed of routers is larger than CNC milling machines, but their Z-axis is quite limited. Therefore, they can handle large objects. But CNC mills have a smaller area for the objects and deep Z-axis.
CNC Wood Lathe
A CNC wood lathe is used for shaping or carving objects. It can be used for wood and various other materials. There is rotary on the machine that holds the objects in its jaws. It revolves around the spindle. The object revolves at a very high speed through a controlled motor. Then, the blade of the lathe is moved toward the object. It removes the material from the surface and creates the desired shape. Similar to other CNC machines, it also requires the CAD file to provide the instructions. Once it has the design, it turns wood on its own.
Laser CNC Machine for Wood
Laser CNC machines are ideal for cutting and engraving wood, acrylic, leather, cardboard, rubber, and various other materials. These machines use powerful laser beams produced by a laser source. The source of the laser can be a CO2 laser tube, diode, or any other technology, depending on the type of laser machine. The laser beams come out of the laser source and are reflected through mirrors in the desired direction. Finally, all laser beams are confined at a small spot through a convex lens. These beams increase the temperature of the object they touch within a fraction of a second.
The temperature is increased abruptly, which causes the change of solid into gas. This direct change of the states without going through the intermediate stage is called sublimation. Thus, the material is vaporized and removed from the surface of the object in a matter of seconds. Finally, you have a cavity that serves as engraving. If the power of the laser is high, then it cuts the material into pieces.
In the case of wood, the material burns due to the high temperature. The heat from laser beams burns material from the surface and turns it into smoke and ashes. It offers an incredible contrast, which looks appealing.
Laser cutting and laser engraving is an advanced technology that has made cutting materials like wood, acrylic, metals, and other materials easier than ever before. It is a safer, quicker, and perfect option. The most important thing about laser processing is the finishing you get at the end. The final products have an impeccable and eye-catching finish.
Suitable CNC Laser Machine for Wood
Laser machines can process a wide range of materials, but it actually depends on the type of laser technology it is using. Each laser machine offers a certain wavelength of laser beams, and materials absorb specific wavelengths only. If the material can absorb the wavelength, it can be cut or engraved without any hassle.
For processing wood, the ideal CNC laser machines are CO2 and diode lasers. CO2 lasers are quite powerful, and they are available in various sizes from desktop machines to industrial machines. These are more expensive due to the laser technology and other features in the machine. A desktop CO2 laser will cost over $3,000, but the commercial ones are over $10,000.
On the other hand, diode lasers are quite affordable. These can process wood, plywood, and engineered wood with utmost perfection. They are less powerful than CO2 lasers but can still do the job well at an incredible speed. They are suitable for DIY, hobbyists, and professionals. A desktop laser machine will cost you around $700 to $1,500.
You can choose a CO2 or diode laser, depending on the budget and usage. Both can cut and engrave wood. If you have a good budget and want to run a small business, select a CO2 laser machine. For DIY and similar tasks, you can go with a diode laser machine.
What You Can Do Using a CNC Laser Machine
The laser has a fine spot that considers tiny details and cuts even small pieces with perfection. You can cut intricate patterns and almost any kind of design using a laser machine. These are quite precise, and you won’t get better results with other types of CNC machines.
With laser cutting, you can make products from scratch. For instance, you can make wall art pieces, wall clocks, wooden boxes, jewelry organizers, puzzles, toys, keychains, and tons of other things. It allows you to cut wood in any shape you like and turn your imagination into reality.
On the other hand, laser engraving is basically used for personalizing objects. You can make logos, write names, engrave photos, or do whatever you like. Nowadays, personalized objects are quite trending. Using a laser machine, you can personalize keychains, wooden cutlery, wall hangings, signs, plaques, and tons of other things. The laser engraves whatever you want, and the best part is that it offers an appealing contrast due to the burning of wood. The result of laser engraving is better than other engraving techniques.
