Starting with the basics, a CNC router machine is an automated machine with specialized tools that utilize a CNC system for automatic carving, cutting, engraving, drilling, and decorative grooving across an array of materials. One of the more popular types is a CNC wood router machine for processing both hard and soft woods. But CNC machines are also great for processing acrylic, PVC, MDF, marble, rubber board, stone, brass, aluminum, and metals such as aluminum as steel, and much more.
One of the biggest advantages of processing material with a CNC machine is its ability to produce complex and precise shapes and contours by machining materials with a tool. That being said, CNC router machines provide commercial and individual users with efficiency and precision that other tools cannot match. These are some of the many reasons why the demand for CNC machines is growing.
A CNC router machine can be used for numerous applications, including:
The Acronym CNC stands for “Computer Numerical Control”. Dictionary.com defines it as an automated operation of a machine by a computer program. A standard CNC router machine (as well as other popular CNC equipment such as plasma, water jet, 3D printers, or CNC laser cutters) is controlled by a computer using a dedicated CNC program. This program stores all the necessary data in the form of so-called G-codes. In short, the G-codes consist of a ‘G’ followed by a number and milling instructions. These codes are standardized, meaning they can be used in practically any type of CNC router machine. Once all data has been entered into the CNC program, the machine can start its work.
There are several different types of CNC router machines one can opt for. At Tork, we provide you with four ATC CNC machines, available in the following sizes - 4x4 wood CNC machine, 4x8 machine, 5x10 CNC router machine, and 6x12 wood CNC machine. We also offer custom CNC sizes based on client specifications.
What differentiates ATC CNC machines from standard CNC router machines is that they come with automatic tool-changing functionality (hence the name - ATC). In other words, an ATC machine can quickly and efficiently meet the tool change requirements without any manual involvement during processing.
An ATC CNC router machine has a separate tool magazine with various tool heads. It uses a computer program to change the required tools, meaning the machine can work without breaks during processing. Generally speaking, ATC CNC machines are considered the most efficient, offering faster tool changing speeds without sacrificing precision.
As covered, at Tork, we offer four sizes of ATC CNC router machines. Also, we offer full customization sizing for your machine. Additionally, you can also equip any router platform with such features as CO2 laser, surface mapping tool, and of course vacuum pumps, a micro misting system, or a dust collection system.

It offers a convenient amount of work space for larger material processing requirements. However, despite its size, it provides incredible precision, as well as ease of use.
Whether your application requires efficient processing of wood, fiberglass, steel, aluminum, or foam, you can rest assured that Tork’s 6x12 router machine will get the job done. It comes equipped with ATC spindles, Tork Touch motion capture software, and an all-in-one PC workstation, just like other machines in our range.
To better understand how CNC router machines work, we need to take a deeper dive into how they are built. Essentially, a standard wood CNC router machine is equipped with five core components - a CNC spindle, motor, router table, control system, and linear rails. We’ll explain them in more detail in the following section.
CNC spindles are electric spindles used for high-speed engraving, drilling, and milling. There are two types of spindles used in CNC router machines - air-cooled and water-cooled spindles. They can be both processed at high speeds and used for similar projects. What differentiates them from each other is their cooling method.
Air-cooled spindles use fan cooling systems. They are easy to maintain and come at a relatively low cost compared to water-cooled spindles. Essentially, they are suitable for users that often experience water shortages or those living in colder regions.
Water-cooled spindles, on the other hand, utilize water circulation to cool the heat generated during the high-speed rotation of a spindle. Their primary advantages include an effective cooling effect, long service life, and low noise. They are more expensive than air-cooled spindles, though, and require more maintenance and attention.
The Motor is the heart of a CNC router machine. Its performance affects the efficiency of the entire machine, and even the tiniest malfunction can have a massive impact on the machine’s performance. When it comes to motors used in CNC router machines, they are divided into two categories - precision machining motors and high-power cut-off motors.
Precision machining motors are generally quieter and come with higher precision properties. They work best when processing fine work pieces, such as nameplates or stamps. They are, however, relatively low when it comes to the power output, which usually doesn’t exceed 250W. This automatically disqualifies precision machining motors from cutting thick materials. For this purpose, it’s better to use a high-power cut-off motor.
High-power cutting motors generate more power and are therefore suitable for cutting and engraving thick materials.
As for the CNC router table, it’s used to carry out the processing work. It’s important to note here that various materials and their shapes may require different types of CNC tables. When it comes to the most common CNC router tables used, you can choose between an aluminum T-slot working table or a T-slot vacuum table.
Aluminum T-slot tables are generally more suitable for pieces with irregular shapes. Such tables use fixtures to keep a work piece steady, ensuring it won’t shake during processing.
As for T-slot vacuum tables, they are composed of a vacuum pump and bakelite board. One of its many advantages is that it’s possible to divide it into six or eight sections, enhancing vacuum adsorption. In general, T-slot vacuum tables provide much more convenient loading and unloading, improving the efficiency of a CNC machine even further. They work best when used for large-scale plate engraving and wood processing.
Essentially, a CNC machine can use either a manual control system or a computer control system. While still popular, manual CNC machines are slowly being replaced by computer-controlled router machines. Router CNC machines are generally more efficient and less prone to making mistakes, as they continuously make corrections and adjustments when processing.
Router machines are also very convenient, as they don’t require practically any human involvement when operating. An operator can display all the functions at the control panel, which is straightforward to understand and operate. Of course, manual machines also have their advantages, requiring less space and effort to learn how to operate them. However, when it comes to production efficiency and precision, they are inferior to computer-controlled CNC machines.
The mounted linear rails on a CNC machine are responsible for securing and guiding the tools. Square rails have a higher load capacity and provide more stability when operating. They also offer more precision and a low-friction resistance, making them suitable for large format processing, especially when working with wood and foam.
Based on the information above you should have a better basic understanding of the advantages of utilizing a CNC router machine. And if you still aren’t sure whether a CNC router machine can benefit your workflow, here are some of the most significant advantages.
