The Best CNC Router With Automatic Tool Change

When dealing with complex processing techniques, especially those that require the use of multiple tools to complete the processing, manual tool change is not only cumbersome, but also seriously reduces the processing efficiency. For hobbyists, this may be acceptable, but for mass production factories, choosing an CNC router that can automatically change tools may be a very wise choice. We have summarized the automatic tool change CNC machines required by various industries for your reference and selection, to help you choose the most cost-effective and best quality machines in 2026 to assist you in realizing your great business plan.

Introduction

We have two ways to implement the automatic tool change function of CNC routers.

One is a relatively simple solution, called a multi-process router or a multi-function switching router. This type of machine is equipped with multiple spindles, each clamping different tools, but these spindles cannot be used at the same time. It controls the switching of multiple spindles through cylinders, and can continuously process multiple processes on one machine. This method of tool change is very fast. Now there is a technology for tool change in 0 seconds. The specific implementation method is: when the tool needs to be changed, the system will pre-start the spindle tool to be used in the next process and make it reach the target speed. After the current spindle completes all processing operations, the target spindle will be switched down immediately for processing, saving the start-up delay time of the target tool after switching the spindle, and improving the processing efficiency, but this type of machine has a limited number of tools to choose from (generally equipped with 2-4 spindles).

The other can achieve true automatic tool change. It is equipped with an automatic tool changer (ATC), which consists of an external tool magazine and a spindle that can change tools. The external tool magazine is divided into two types: linear and carousel, with 4, 6, 8, 12, 16 tool magazines available. The automatic tool change spindle is also specially designed to automatically remove and clamp the tool. This type of machine is equipped with a tool length sensor to automatically adjust the Z-axis height and automatically calculate tool compensation, which improves work efficiency and reduces the difficulty of operation.

What is The Difference Between a Linear Tool Changer and a Carousel Tool Changer?

At present, the two most common tool magazines on the market are linear tool magazines and disc-type tool magazines. Let's talk about the advantages and disadvantages of the two types of tool magazines respectively.

• Linear tool magazine: This type of tool magazine is arranged in a straight line, it has a simple structure and is cheap. It is divided into fixed-type tool magazine and follow-type tool magazine. The fixed-type tool magazine is usually installed at the tail of the machine, whenever the tool needs to be changed, the gantry needs to move to the tail end of machine to complete the tool change operation, and then move back to the processing position to continue processing. This reciprocating process is a waste of time. After continuous updating and development, there is also a follow-type linear tool magazine to choose from. It is usually installed under the gantry of the CNC router and can move with the gantry,when changing the tool, the cylinder pushes the tool magazine out. It greatly saves the time of changing the tool to and from the tail of the machine tool and improves the processing efficiency.However, the structure of the follow-type tool magazine has certain limitations. Since it is placed under the gantry, it will affect the maximum height of the workpiece that the machine can process, and it is usually used in the production of cabinets, wardrobes, wooden doors, office furniture and other industries,the products processed in these industries are mostly sheet materials with a thickness of no more than 100mm.

• Carousel tool change magazine: This type of tool magazine is a carousel-style structure, which is driven by an independent servo motor to rotate for tool change. This type of tool change structure is stable and the tool change speed is faster. It is generally installed on the side of the machine gantry and moves with the gantry, without affecting the processing height of the machine. Its disadvantage is that the cost is relatively high, and because it is equipped with an independent servo motor drive, the machine needs to add a control axis, which makes the price of the CNC system rise accordingly, further increasing the price of the machine.

There is no difference between the two tool change methods in the user's daily use and operation, and the difficulty of learning and operation is basically the same. Their difference is mainly reflected in the mechanical structure design, and users can choose according to their own budget and processing needs.

What Other Function Packages Can be Selected to Enrich the ATC Router?

• Automatic loading and unloading: Adding this function can greatly save the time and workload of manual loading. Two or three suction cup devices are added behind the router gantry to grab the plate from the hydraulic storage platform and drag the plate to the processing area through the movement of the gantry. Then, the positioning cylinder accurately positions the plate, and the vacuum adsorption platform adsorbs it before processing. The hydraulic loading platform is usually equipped with a sensing device that can automatically adjust the height according to the number of stacked materials to ensure that it is level with the machine platform. After the plate is processed, the pusher device located under the gantry will automatically drop and push the processed finished product to the unloading platform through the movement of the machine gantry. The unloading platform usually adopts a conveyor belt structure with sensing devices at both ends. Once it detects that material is pushed onto the platform, the conveyor belt starts to rotate and automatically stops when the material is delivered to the end of the platform.In addition, the automatic loading and unloading system of the CNC router is highly flexible and scalable. The number and layout of the loading and unloading mechanisms can be flexibly adjusted according to production needs to meet the production needs of different scales and types. Moreover, it can also form an intelligent production line with other automated equipment such as robots, edge banding machines, drilling machines, labeling machines, etc., to realize the automation and intelligence of the entire production process, truly liberate manpower, and create a fully automated unmanned workshop.

• Drilling package: The drilling package can perform drilling operations at multiple holes at the same time, greatly improving production efficiency and suitable for rapid mass production. This advantage is particularly evident in cabinet production. Its processing accuracy can reach ±0.02mm, which can ensure the vertical accuracy of the hole position and meet the needs of high-precision furniture production. The drilling package is combined with the CNC router system to realize automated operation, so that the raw material cutting and drilling are completed at one time, reducing manual intervention to avoid errors caused by secondary processing, effectively improving product quality and accuracy, and ensuring that panel furniture can be seamlessly connected during assembly.

• Saw blade: When cutting hard or thicker plates such as solid wood boards, honeycomb aluminum, and thickened solid wood boards, using ordinary cutting tools may require layered cutting, low cutting efficiency, and even difficult to cut aluminum plates. Saw blades can easily cut various types of plates, improve cutting efficiency, and reduce tool loss.

• Oscillating knife: If the business scope is wide, and it also involves the cutting of soft or foamed materials such as cloth, leather, carton, corrugated board, sponge, latex, etc., then a oscillating knife cutting machine is needed. However, purchasing a oscillating knife cutting machine alone is expensive and takes up space. You can choose to add this function directly to the CNC router to meet the needs of diversified business.

• Fourth axis rotation axis: When 3D carving such as European table and chair legs, figures or special-shaped cylinders is required, this function can be added to achieve four-axis linkage carving.

Application of ATC Router

Processable materials: various solid wood boards; aluminum-plastic boards, insulation boards, compact boards, epoxy boards, acrylics, density boards, composite boards, carbon fiber composite materials; soft metals such as copper and aluminum.

In the furniture manufacturing and decoration industries, automatic tool changer routers are widely used in solid wood doors, composite board doors, cabinets, wardrobes, office furniture, finished panel furniture, etc. In addition, it can also be used for milling and engraving of furniture products such as 3D corrugated board processing, craft sash windows, screens, sliding doors, painted doors, craft wooden doors, cabinet doors, as well as cabinet cutting, punching, grooving, etc.

How to Operate ATC Router?

Many users may find the automatic tool change router quite complicated to operate, and even worry about how to use it after purchasing it. In fact, for users who purchase new equipment, there is no need to worry about this. As long as you choose a formal factory with a certain scale, after completing the purchase of the machine, the manufacturer will provide you with a full range of systematic training covering machine programming, operation and maintenance, and will also provide a machine tutorial manual or a matching teaching video. Next, we will briefly sort out the specific operation steps of the CNC router for your reference.

Pre-processing Operations

1. Turn on the power and turn the machine switch to the ON state.

2. Check whether all parts of the router are normal, such as whether the vacuum pump is powered normally, whether the vacuum pump pipe is firmly connected, and check whether the vacuum adsorption table is blocked by sawdust and dust.

3. Put the tool into the tool holder and tighten it, and manually install it into the tool magazine of the router. Pay attention to the installation order to avoid damage to the workpiece due to incorrect tool replacement during processing.

4. Put the material to be processed on the workbench and fix it. Note that the material should be placed flat and the edge should be flush with the workbench. Usually the router is equipped with a positioning cylinder, which can be positioned by just leaning against it. If this function is not available, it is best to design a simple tooling to assist positioning to ensure work accuracy.

Processing Operations

This operation takes the LNC system as an example.

1. Power on

   After powering on, you first need to return to the mechanical origin. Operation method: click "ZRN" on the interface, and then click "START" on the interface.

2. Tool setting

   Click "Compensation group" and "ATM" on the interface in turn, and then number all processing tools on the interface. After completion, click "Start" on the interface, and the router starts automatic tool setting.

   After tool setting is completed, the router stops automatically, and then we need to switch to tool No. 1, and then use the handwheel to move the XY axis to move tool No. 1 to the lower left corner of the plate, and then click "Teaching input" on the interface, and then click "Set X" and "Set Y" to set the coordinates respectively. Then return to the "ATM" interface, click "Z drop" on the interface, and all tool setting settings are completed.

3. Read program

   First insert the U disk, click "USB imP", then select the file in the U disk, and then click "transmission". After waiting for the transmission to complete, click "open file", and then select the file just imported. The file reading is completed.

4. Start operation

   The new program can be tested by using the handwheel simulation function. The operation method is: click "MEM", "MPG DRY", and "Start" on the interface in sequence, and then turn the handwheel to start the router test run.

   After the handwheel test run is completed, click "MPG DRY" on the interface again to turn off the simulation function, and then click "Start" on the interface, and the router will start to run automatically.

Troubleshooting of CNC Machines

Observe the fault phenomenon: When the machine fails, you first need to observe and determine the specific phenomenon of the fault, such as the spindle does not rotate, the XYZ axis does not respond, the equipment makes abnormal sounds, etc.

Analyze and solve the fault: According to the fault phenomenon, combined with the working principle and structural characteristics of the CNC router, analyze the possible causes. The spindle does not rotate may be an inverter alarm. At this time, you should refer to the inverter's instructions to determine the cause of the alarm, such as overload, lack of phase, etc. If the drive motor does not respond, check whether the drive power supply is normal and whether there is an alarm phenomenon. If the display is not bright, it is a power supply system problem, so the line should be checked. If an alarm occurs, refer to the manual to find the corresponding alarm code, find the cause of the alarm to eliminate the alarm. If the equipment responds abnormally, first observe whether there is any foreign object stuck in the machine, or check whether the lubrication system is normal, whether the slider is damaged, etc.

If the problem still cannot be solved, it is recommended to power off the entire machine and cut off the gas source, contact the manufacturer's after-sales engineer to communicate, and investigate the cause of the fault and solve it.

Machine Maintenance

• Daily cleaning: After the daily work, you should carefully check and clean the wood chips or dust left on the machine, especially the foreign objects attached to the guide rails and screws, to extend the service life of the machine and reduce the failure rate.

• Lubrication maintenance: Before starting the machine every day, you need to check whether the oil level of the electronic lubrication system is higher than the minimum oil level line, whether the oil circuit is blocked, and ensure the normal operation of the lubrication system.

• Gas circuit and pressure inspection: Before starting the machine every day, you should check whether the equipment air supply system has reached the optimal working air pressure and whether the vacuum pressure is normal. Ensure the safety and reliability of the processing process.

• Regularly replace wearing parts: Regularly replace wearing parts such as tools, oil filters, guide rail protective covers, etc. Ensure processing effect, processing accuracy and performance, and improve processing quality and efficiency.
