The Definitive 4×8 CNC Router Guide For 2022

CNC routers are becoming more and more popular in the woodworking community. As this popularity has increased, so has the number of companies producing excellent routers.

There are many hobbies CNC routers are too small for creating large products. This is why 4 x 8 CNC routers have become so popular in the past decade.

If you are a hobbyist or professional looking to buy a 4×8 CNC router, finding the right machine is like finding a needle in a haystack. There are many options with different specifications and price ranges, so CNC conducted research to make sure you choose the 4 x 8 router that suits you best.

4×8 CNC Router Buying Guide | How to choose the right 4×8 CNC router?

When you start looking for a new wood CNC router, there are many factors to consider. Important factors that need to be considered include the machine’s spindle, controller, compatible software, safety mechanism, and durability. Of course, you also need to pay close attention to the price. The following FORSUN CNC will introduce in detail.

The working mode and power of the spindle are very important for CNC milling machines. There are generally two types of spindles. One is a water-cooled spindle, and the other is an air-cooled spindle. Choose the right spindle, it depends on your material and the highest temperature of the local weather in your country/region.


1) If your material is soft, such as MDF, PVC, you will not be able to make small pieces of handicrafts, a water-cooled spindle with lower power, 2.2KW, 1.5KW will do.


2) If you want to produce furniture or doors, engraving, and cutting, we recommend that you choose an air-cooled spindle. When the material is solid wood, the spindle power should be above 3.5KW.3 Axis Single Head CNC Router Machin


Air Cooled Or Water Cooled CNC Spindle, Which Is Better?


Control System

CNC engraving machine control system As we all know, the operation of a woodworking engraving machine is closely related to its control system. The CNC router controllers on the market mainly include computer control and handle control.


Computer control system: Computer control is to install a control card on the PCI slot of the computer motherboard and install a driver on the computer to control the trajectory of the XYZ axis of the engraving machine and the rotation of the spindle motor. Through this control method, the operator can preview the processing effect, can see the processing track at any time, and correct in time if the program is loaded incorrectly. It has the characteristics of a friendly interface, simple and convenient operation, complete functions, and strong program compatibility. And various engraving CAM software can be imported directly or indirectly. The disadvantage is that the computer needs to be configured separately, but fortunately, the requirements for computer configuration are extremely low. For customers with a small budget, you can configure second-hand old computers.


Handle control system: Handle control is a control method that can be used to control the movement of the CNC woodworking engraving machine. The biggest advantage is that it saves space and does not require a computer. The space occupied by the equipment is greatly reduced, and the knife is more convenient. The disadvantage is that the operation is more troublesome. After all, all functions are concentrated on one control panel. If you are not skilled, it is easy to press the wrong function key. More importantly, the disadvantage is that there is no preview and other functions, and the interface is not as intuitive as a computer.


The above is an introduction to the advantages and disadvantages of computer control and handle control methods. It is recommended that users choose a control method that suits their processing needs according to their own budget, operating capacity, and other factors.


CNC router machine transmission mode

Transmission mode of CNC engraving machine In the field of CNC engraving machines, there are two transmission modes: rack drive and screw drive.


The screw drive is the drive mode of the origin of the engraving machine. High precision, slow running speed, high environmental protection requirements, and relatively short service life. The Y-axis single screw is not easy to be too long (the model cannot be too large). It shakes easily. If the installation accuracy is not high, the Y-axis screw may be lost for a long time. If the accuracy is too high, the Y-axis twin-screw structure can meet the processing requirements. The screw drive is mainly used for carving, wood products, small handicrafts, lighter stone, etc. in the advertising industry.
