ATC CNC Router
What is ATC in CNC?
Generally, an Automatic tool changer or ATC is used in computerized numerical control (CNC) machine tools to improve the production and tool carrying capacity of the machine. ATC changes the tool very quickly, reducing the non-productive time. Generally, it is used to improve the capacity of the machine to work with a number of tools. It is also used to change worn out or broken tools. It is one more step towards complete automation.
Simple CNC machines work with a single tool. Turrets can work with a large number of tools. But if even more tools are required, then ATC is provided. The tools are stored on a magazine. It allows the machine to work with a large number of tools without an operator. The main parts of an automatic tool changer are the base, the gripper arm, the tool holder, the support arm and tool magazines. Although the ATC increases the reliability, speed and accuracy, it creates more challenges compared to manual tool change, for example the tooling used must be easy to centre, be easy for the changer to grab and there should be a simple way to provide the tool’s self-disengagement. Tools used in ATC are secured in toolholders specially designed for this purpose.
In which industries are the ATC CNC router applied?
- Woodworking industry: Processing of three-dimensional wave board, cabinet doors, solid wood doors, craft wooden doors, paint-free doors, screens, craft window, and auxiliary processing of shoe polishers, game machine cabinets and panels, mahjong tables, computer tables and panel furniture.
- Advertising industry: Advertising signage, logo making, acrylic cutting, plastic molding, and processing of various advertising materials and decorative products.
- Mold industry: It can engrave copper, aluminum, iron and other metal molds, as well as artificial marble, sand and stone, plastic plates, PVC pipes, wooden boards and other non-metal molds.
- Craft gift industry: It can carry out a variety of shadow carvings, reliefs, and widely used in crafts industry.
Why to choose the ATC CNC Machine?
First, high productivity. Equipped with automatic tool changing device, which can meet the tool changing requirements during processing without manual participation. With simple and easy operation mode to learn, which can help users quickly grasp the use of methods and greatly improve production efficiency.
Second, imported spare parts.
- Adopting the automatic tool changing spindle, it has the advantages of good starting performance, fast processing speed, large torque and high processing efficiency.
- Adopting Italy HSD spindle motor, and spindle bearings with high-precision ceramic bearings, it has the advantages of low noise and long service life.
- Equipped with the imported high torque servo motor, it has the advantages of low noise, fast speed and high positioning accuracy.
- Equipped with a unique tool changing device and a dedicated tool setting table, it can realize automatic tool changing without intermittent with fast tool changing speed, and can accurately compensate for tool length errors.
- Adopting Taiwan linear guide and ball screw, it has the advantages of high bearing capacity and accurate cutting.
Third, good software compatibility. Adopting open software interface, it can be compatible with the processing codes generated by various CAD / CAM design software, such as type3 / Artcam / JDpaint / Wentai, to ensure the realization of various design functions.
Types of ATC in CNC:
Depending on the shape of the magazine, ATC can be of two types: 1) Drum Type changers(Disc/ carousel Types) are used when the number of tools is lower than 30. The tools are stored on the periphery of the drum. 2) Chain type changers(Liner Types) are used when the number of tools is higher than 30(The number is different depending on the design and manufacturer. It is important to note that the number of tools for the drum type is fewer than the chain type). But the tool search speed will be lower in this case.
Automatic Tool Changer Mechanism:
After receiving the tool change command, the tool to be changed will assume a fixed position known as the “tool change position”. The ATC arm comes to this position and picks up the tool. The arm swivels between machine turret and magazine. It will have one gripper on each of the two sides. Each gripper can rotate 90°, to deliver tools to the front face of the turret. One will pick up the old tool from turret and the other will pick up the new tool from the magazine. It then rotates to 180° and places the tools into their due position.
Functions of ATC:
The use of automatic changers increases the productive time and reduces the unproductive time to a large extent. It provides the storage of the tools which are returned automatically to the machine tool after carrying out the required operations, increases the flexibility of the machine tool, makes it easier to change heavy and large tools, and permits the automatic renewal of cutting edges.

Application and Projects
ATC CNC Router
ATC CNC router is the first choice for enterprises with large production volume. Compared with the traditional manual tool change production method, this type of wood CNC machine has an independent tool magazine with different tool bits. It can automatically change the required tools by computer program control without stopping work during processing. And this CNC wood router can complete a series of cutting, hollowing, grooving, punching, milling grooves, milling planes and other different processing needs. Therefore, both the processing quality and processing efficiency have been greatly improved.
According to the different tool changing methods, the ATC CNC engraving machine can be subdivided into linear ATC CNC and disc ATC CNC machines.
Then we are talking about the linear ATC CNC Machine. This type machine uses a straight-line tool change device, and the tool change device can be installed in different positions according to the specific needs of the user. Firstly, the in-line tool magazine can be placed behind the bed. This conventional in-line tool changer engraving machine is cost-effective and can meet a variety of processing requirements for complex work pieces without high procurement costs. Secondly, the in-line tool magazine can also be placed under the gantry. This type of linear engraving machine does not need to go to the back of the bed to change tools, so the tool change speed is faster and the wear on the guide rail can be reduced, and the service life of the machine is relatively longer. It is worth mentioning that the number of tools in the in-line tool magazine can be customized according to the specific processing needs of the user.
Next we are talking about the carousel ATC CNC Machine. This type machine is also one of the most selected by users. The position of the disc magazine can also be selected according to user needs. On the one hand, the disc magazine can be placed next to the spindle. The biggest advantage of this type machine is the fast tool change. However, the number of tool bits should be guaranteed to be within 20 tools. If the number of tool exceeds 20, the weight of the cutter head will increase, which will affect the bearing capacity of the Z axis and the gantry, especially the Z axis screw and the guide rail slider. And all these will affect machining accuracy. On the other hand, the disc magazine can be placed on the side of the gantry. This type of automatic tool changer engraving machine is not limited by the number of tools and has better stability. It also guarantees the processing accuracy of the machine and ensures that the ATC CNC router machine will be used for a long time, and processing accuracy is not affected.
This CNC router is a high-speed, automatic load/unload, heavy-duty CNC routing system for nested based feed through machining. This CNC machine is used majorly in the production of cabinets, closets, and custom furniture. Double workbench, equipped with 9KW Italy aircooling spindle. More than 80 pcs board be done per day.
