Best 4-axis CNC Routers with Extra Rotary Axis [2022]

Best 4-axis CNC Routers with Extra Rotary Axis [2022]

Best 4-axis CNC Routers with Extra Rotary Axis [2022]

In a four-axis CNC router, there is an additional rotary axis (A-axis) that allows you to do rotary cutting and indexing for making cylindrical/round parts.

A typical CNC router only has three axes and moves the cutting tool in the X, Y, and Z axes to remove material from the stock.

If your goal is to make parts such as cylindrical columns, fluted columns, spirals, pens, and chess pieces, a 4 axis CNC router is what you need.

The additional axis turns your CNC machine into a mini wood lathe.

In this article, I'm going to introduce to you the best 4-axis CNC routers available on the market with a detailed overview of each.

The additional fourth axis can be an extra axis that moves the tool or it can be an axis that moves the workpiece.

The products featured in this list rotate the workpiece to provide the fourth axis motion.

I also discuss 4-axis CNC machining in the latter part of this article with examples and illustrations.

Avid CNC PRO4896 (Souce: AvidCNC)

Avid PRO4896 4' x 8' CNC router is one of the most popular CNC from Avid's long list of CNC routers.

It can be fitted with an Avid CNC Rotary Axis attachment kit to achieve 4-axis movement.

Size

Avid's PRO4896 has a footprint of 115 ½“× 67” and a cutting area of 49 1/2“ × 98 3/4“.

It has a height of 43 3/8" from its foot to the top and weighs around 483 lbs. With the optional leg kit upgrade, the height can be increased to 77 1/2".

Material Capability

PRO4896 CNC can cut materials like softwood, hardwood, plywood, high-density plastic, foam, balsa, MDF, baltic birch, and aluminum.

Chassis

The frame of Avid PRO4896 is made of heavy-duty aluminum and steel plates.

A series of crossed frames support the work area and it provides great rigidity to the machine.

Linear Motion

PRO4896 CNC uses a PRO rack and pinion system with linear guides to guide the X and Y-axis machine movement. Y-axis is driven by two stepper motors to prevent it from racking.

The Z-axis of the CNC is guided by precision ball screws. They are more efficient than lead screw systems.

Spindle

Avid offers two optional plug-and-play compatible spindles from Hiteco for the PRO4896 CNC router.

You can either get the spindles that Avid offers or can use any other spindle of your choice.

Controller and Electronics

Avid offers you the option to choose their control system or you can customize it with any other control system of your choice.

The control system from Avid CNC is plug-and-play compatible, it houses a 32-bit CRP5056 stepper motor driver and uses an Ethernet SmoothStepper breakout board.

You can also choose between NEMA 23 and NEMA 34 stepper motors while purchasing the product. I suggest you get NEMA 34 stepper motors if you need a high rate of production.

Software

For CAD you can use most CAD software of your choice and for CAM you can use LazyCAM as an add-on with Mach4.

The go-to control option for Avid CNC PRO4896 is an Ethernet SmoothStepper board with Mach3 or Mach4 control software.

Avid recommends using Mach4 motion control software for controlling PRO4896 CNC.

Upgrades

Avid PRO4896 CNC router is greatly customizable, while buying you have the option of choosing stepper motors, spindle, controller, gantry width, and Z-travel of your choice.

Avid provides many upgrade options for the PRO4896 CNC. The Rotary Axis attachment is the one you need to achieve fourth axis capability on this CNC router.

The Avid CNC Rotary Axis attachment comes in many different sizes and can be added to all the CNCs in Avid's PRO and Benchtop series of CNC machines.

Rotary attachment makes the PRO4896 CNC cutting and indexing compatible and helps you achieve 4-axis control to machine many complex designs.

The PRO4896 CNC can be expanded to increase its work area and can also be fitted with a laser or plasma cutter.

The rotary axis uses a NEMA 34 stepper motor, 5" four jaw chuck, planetary gear reducer, independent framework, and profile linear rail guides.

The NEMA 34 motor can spin the jaw holding the workpiece at a maximum speed of 100 RPM.

It provides the holding torque required for both indexing and speed required for rotary milling operation in a production environment.

The rotary is self-contained in a rigid all-metal framework to maintain high precision alignment between the chuck and the tailstock.

It has a footprint of 49" x 14.02" and a height of only 6.93" which makes them easily mountable on the work table.

The rotary linear guides allow for a quick and easy setup for different workpiece sizes without giving away the precision alignment of the axes.

Avid also offers software-guided alignment for the rotor. It's fully integrated with their Auto Z and corner-finding touch plate and will work seamlessly with Mach4 software.

Their post-processor uses inverse time feed rates that prevent the production speed from slowing down during programs with combined linear and rotary motion.

The rotary axis is highly versatile, it can be mounted to the PRO4896 CNC router parallel to the X or Y-axis and can be recessed to the machine to help maximize the workpiece diameter.

They also have detailed instructions on assembly, different mounting options, and the electronics of the rotor axis. It is available on the website and in the user manual.

Accessories

Avid offers various accessories like a leg kit, auto Z and corner finding touch plate, proximity sensor kit, composite nailer, dust shoe, plasma kit, and a rotary axis.

Assembly

PRO4896 CNC has a modular design and is shipped in parts. It can have a long assembly process and can take up to 40 hours to complete the full build.

Avid provides a lot of simplified resources for you to refer to and learn while assembling the machine.

Community and Customer Support

Avid has a large and active customer base, most of the people who use this machine are business owners who machine different products for a living.

Though Avid doesn't have an official forum, its customers are active across websites like Router Forums, CNCzone, Facebook, and YouTube.

What is 4-axis CNC machining?

ARK360 - Axiom 4th axis rotary kit
ARK360 - Axiom 4th axis rotary kit (Source: Axiom Precision)

The 4th axis movement in a CNC is achieved by the same X, Y, and the Z-axis with an additional axis of movement, this axis is called the A-axis.

In most cases, a 4-axis router kit is used to achieve 4-axis machine movement but to control this additional axis you'll need to have a 4-axis compatible controller.

A-axis illustration
4-axis illustration (Source: CloudNC)

To put it in a simple form, the standard 3-axis together with the A-axis gives you a 4-axis setup. A-axis is the rotational axis that turns the workpiece.

The workpiece is mounted onto the A-axis and it rotates like in a lathe. Here the workpiece turns and exposes all its sides to the tool to work on.

Let's look at 4-axis machining with an example. In the following image, a piece of wood is loaded on a Shark 4th axis turner.

Rockler 4th axis kit loaded with a piece of wood

The 4th axis turner rotates and exposes all the sides of the wood as the spindle moves along the X, Y, and Z axes and mills on the wood.

Such a machine movement helps you work all around the wood instead of just working on the face of the wood as we do in 3-axis machines.

4-axis machining brings in a great deal of flexibility to your CNC machining process, enabling you to create some of the complex designs that otherwise would not be possible.

Frequently Asked Questions (FAQs)

Why are 4-axis CNC Machines costly?

4-axis CNC machines are costly because there is a lot of research and development going into building all these machines. You require 4-axis supported controllers, software, and CNC machines to do 4-axis machining.

Also, 4-axis designs require a high precision system to design those models. To make high precision systems you need to use a rigid machine built with well-calibrated electronics. As there are more moving parts in the machine, the operating complexity increases, and a lot of support systems are required to keep the machine running.

What is 5-axis CNC machining?

In 5-axis machining, two rotational axes operate separately to rotate the workpiece in many different angles with respect to the cutting tool. The machine may utilize either A-axis or B-axis with the C-Axis to achieve this feat, all these are rotational axes.

In 4-axis CNC machining only one rotational axis is there, but with 5-axis machining you can achieve two rotational axes that can operate independently. It brings in a great deal of flexibility in your CNC machining.

Do 4-axis CNC require separate software?

Yes, due to the advanced system a 4-axis CNC requires a separate CAM and control software that supports 4-axis machining.
