4 Axis Multi Head CNC Router With 4th Axis Rotary Table

4 Axis Rotary 3D Machining Demo of EA-1825RMS10

Let's first have a look at the background of the video. In the video, the 4 axis multi head cnc router EA-1825RMS10 is milling 3D furniture parts with solid wood. There are two procedures in total: roughing and finishing. Two types of bits ( 12.7mm straight flute bits and 6mm V-shaped bits) and two pieces of toolpath files are used. Now you probably have a question:

Q: How long will the rotary axis cnc router take to complete the design in the video?

A: For the exact design in the video, it takes 6 hours to finish. We got 10 pieces in 6 hours since 10 spindles and 10 pieces of the cnc router 4th axis work together. By calculation, we can know that each piece costs 0.6 hours on average. 

Technical Advantages of Multi Head 4 Axis CNC Router With Rotary Table

Its biggest advantage comes from its dual-application working platform, a dual exchange table system for rotary and flat milling. The two platforms can be switched at will according to actual production requirements. One end of the rotational platform is a mobile carriage; when the flat platform is required, the mobile carriage can be pushed to the rear part of the 4 axis cnc machines and leave space for the flat table. So, we can get the flat table installed there and execute flat machining.

Since the flatbed size (2000x2500mm) is relatively large, if it is designed as one piece, it seems impossible for us to install it manually. Our strength is not enough to lift it.

Therefore, we divided it into two pieces, one on the front and one on the back. The size of each piece is 2000x1250mm. As shown in the picture below, this is what it looks like after the rear piece is installed.

In order to make the installation easier, we installed several small pulleys under the flat table. Same as the rotational table, it is supported by the heavy-load round linear guides as well.

EagleTec Multi Head CNC Router with 4th Axis Specs

• The headstock of the rotary is a dual-drive design, which is driven by two sets of Yaskawa 850 watts servo motors to obtain sufficient power.

• The headstock part is composed of many precision transmission components. To ensure it runs smoothly, it is closed by a casing to prevent machining debris from falling into and causing machine failure.

• The electrical part is designed with the most reliable performance standards. As shown below, the 4 axis wood cnc machine uses a total of 6 sets of Yaskawa servo motion systems; both the headstock and the Y-axis are dual-driven; It also uses 10 inverters, so that each one controls an electric spindle; this combination is undoubtedly the most reliable one since one control one is more stable than one control couple.

• The multi-head 4th axis cnc router machine is equipped with a WEIHONG 4-axis simultaneous motion controller based on the windows system. This is because multi-head router machines are mainly used for engraving, and the tool path files of such machining are often very large; a computer is prior to a handheld DSP unit on the performance of both reading and running files. 

• The electrical connection between different parts of the machine is plug and play.

• It supports re-carving after power failure.

FAQs about Multi Head 4 Axis CNC Wood Carving Machine

Q: Currently, With A Distance Of 180 Mm Between Each Spindle, I Assume That The Working Area On The Flat Table For Each Spindle Is 180 Mm X 2500 Mm, As For The 4th Axis. Can You Confirm This?

A: Correct. We confirm the working area on the flat bed for each spindle is 180 mm x 2500mm; and the same for cnc 4th axis.

Q: Would It Be Possible To Enlarge The Working Area For Each Spindle By Using Only 5 Spindles Instead Of 10? If This Configuration Is Feasible, Could You Tell Me What The New Working Area Would Be For Each Spindle?

A: Yes, it is possible to enlarge the working area for each spindle by using fewer spindles instead of 10.

This can be divided into two situations. When using the flat table, we can use 5 spindles (No.1, No.3, No.5, No.7, and No.9) and the maximum working size of each spindle is 360mm x 2500mm; however, when running rotary units, spindles 3, 5, 7, and 9 can reach a working range of 360mm x 2500mm. In this case, spindle No. 1 cannot get an enlarger work range. This is because the working range of the rotary axis extends from the center line of the workpiece to the left and right sides. The No. 1 spindle is located on the far left side of 4-axis cnc table. Due to the limitation of the left side boundary of the machine base, the working range cannot be increased to the left, resulting in the processing range of the No. 1 spindle cannot be increased.

Q: What Is The Maximum Z Distance On The Flat Table?

A: The distance between the gantry bottom to the top surface of the flat bed would be 300mm. 

Q: Is There A Larger Model of the 4th Axis CNC Machine, With A Distance Between The Spindles Greater Than 180 Mm (While Retaining 10 Spindles)?

A: We don't have any issues with building a larger 4axis cnc. However, if container loading for sea shipping is taken into consideration, it might be a problem. Due to the width limitation of the container, we won't be able to get any larger model accommodated in it. 

Q: Which Spindle Will Be More Durable for This 4 Axis Multi-Head CNC Router Machine?

A: Seeing from the users' feedback, EagleTec CNC strongly recommends the water-cooled constant-torque electric spindles; this type of spindle is the most durable one and has a lifespan of 2 to 3 times longer than regular water-cooled spindles.

Q: What Advantages Does Your Multi Head 4 Axis Router Machine Have?

A: This machine has 10 spindles, and they are often worked simultaneously, so the load on the Z-axis is relatively heavy. If the machine uses the same Z-axis transmission structure as the ordinary machine, this part will soon stop working. In addition to the use of servo motors and dual-balanced cylinders, EagleTec CNC has also made a reasonable transformation of the connection between the motor and the ballscrew, which offers splendid durability in the Z-axis.

Q: What is the Minimal Distance Between Two Spindles of this 4 Axis CNC Wood Router?

A: It is 148mm from center to center.

Q: How Much Space Does One Spindle Take Up On the Gantry Rail/Track of the CNC 4 Axis Router?

A: It is 148mm.

Q: What is the Maximum Distance Between Two Spindles of the Rotary CNC Machine?

A: The standard package would be 180mm from center to center.

Q: How Do You Get Such A Big Multi Spindle 3d CNC Router to Be Shipped?

A: Based on the dimension of this machine, we will have to take the gantry down before loading. Because the door width of all typical containers is 2.35m, our machine width is much larger than this size. SKD packing way would be the solution for this.

Q: What Is the Lead Time for This Multi Head CNC Router with a 4th Axis?

A: It goes into production on receipt of the down payment; We can get it ready within 15 business days.

Q: What Kind of Warranty Do You Offer for This Multiple Head Router CNC Machine?

A: It's a 12-months warranty since the departure. Under warranty, you’ll enjoy free replacement for any broken parts except Vulnerable parts. After that, we provide you with constant free online support as well; spare parts replacement will be charged based on raw materials cost.
