How Does a 4 Axis CNC Mill Compare with 3 and 5 Axis Mills?
A “normal” CNC milling machine has three axes, the X, Y and Z axis. From the front of a machine, the X axis is left to right, the Y is front to back and the Z is up and down. The workpiece is stationary on a bed and the cutter does all the moving (unless there is a T-slot bed.)
3 Axis CNC Mill: This configuration can mill slots, drill holes, face off parts with the cutter in the vertical direction only.
4 Axis CNC Mill: Generally, the 4th axis rotates around the X axis (which moves left to right). This allows you to make holes and slots in the front and back of the workpiece. The cutter can rotate around the part which is fixed on a table. The fourth axis is called the A axis.
5 Axis CNC Mill: When the A axis is at zero, a fifth axis would be perpendicular to the Z axis. The cutter can be rotated 90 degrees towards to the front of the machine and moved to allow for milling around the sides of the workpiece. The 5th axis is called the C axis.
So, the complexity of parts that can be made in one setup increases as the number of axes goes up.
Selecting the Best Type of Used 4 axis CNC Lathe
When deciding on the type of used 4 axis lathes to purchase, key factors to consider will be part complexity, part mix and the average number of parts to be run per setup.
Part Complexity: Do you want to machine complex parts? Consider the number of tool pockets available – the more stations, the more complexity in one setup. Some 4 axis lathes have tool holders on both a turret and in a magazine.
Primary Industry: Is your shop dedicated to a single manufacturing field like automotive, aerospace, mold & die, medical device or oil? The different industries have different demands for torque, speed and precision. For example, medical devices frequently require smaller, high-precision parts. Aerospace demands difficult to machine materials and many large parts. This would indicate that you need a 4 axis CNC mill that with power for handling tough materials.
Physical Size: You’ll want to consider the physical size of your used CNC 4 axis machine. This will be dictated by the size of parts that will be machined in turning diameter, length, X, Y and Z travel as well as other axis travel in degrees. Then you’ll need to determine the rigidity and horsepower requirements by thinking about the types of materials that you will be machining. Keep in mind that some multi-axis machines are better than others for particular applications. It is helpful to learn if a particular used CNC machine was used in a similar application before. Often, 4 axis CNC machines are built to order per a specific customer’s needs. When you buy used, you’re looking for the closest fit from existing machines instead.
Options to look for on used 4 axis CNC lathes:
- Coolant system
- Sub spindles
Y Axis milling
- C axis capability (can you add a 5th axis later?)
- Live tooling
- Rotary live tooling / milling options on turrets
- Chip conveyor
- Part catchers
- High pressure coolant options
- Wiring for probes
- Tool changer (ATC / number of positions)
- Auto-lube systems
- 3D Coordinate conversion
- Connectivity options – RS-232 ports, memory cards, PCMCIA, wireless options
- Operating system – Windows? This is necessary for MTConnect software.
- LCD Screen size and type
- Bar feeder systems
Found a 4 axis CNC mill for sale that looks interesting? Here’s what you can do before you go see it.
- Ask for good photos. Zoom up in the photos and look for signs of damage and worn components.
- Speak with a local machine tool service provider who can provide service for the machine.
- Search similar years for the 4 axis CNC model to see how pricing compares.
- Get the hours of operation.
- Ask for the maintenance records of the specific 4 axis CNC lathe that you are considering.
- Ask for the 4 axis CNC lathe manual that came with the machine.
- Find out if any tooling or other accessories are being offered for sale along with this 4 axis CNC lathe.
Once you’ve done your homework, and you think you’ve finally identified the perfect used CNC 4 axis CNC mill for your company, we recommend that you inspect it yourself or hire someone to inspect it on your behalf. Here are some inspection tips below.
How to Inspect a Used CNC 4 axis CNC Mill
- Inspect for damage and worn components. Carefully look all over the machine. A good used 4 axis CNC mill for sale should show little wear since they are built to last for years.
- Ask to operate the machine to see it run. Make some chips!
- Listen to the sounds of the axis moving at different speeds
- Run the spindle(s) at the max RPM.
- Look at the guards and sensors on the machine. If sensors, switches, wires, and hoses all match and look like they match well, that’s an indication of a well-maintained machine.
- Make parts on the machine if possible.
- Check the tool-changer/turret(s). How quickly does it change tools?
- Check the electrical cabinet for anything that looks like “not factory” and ask about it.
- Ask the owner why he’s selling the machine.
- Find out what process controller is on the machine. Have they done any upgrades?
- Review bar feeder options.
- Review chip & coolant management options.
- Find out the electrical requirements for install (should be on the serial number plate.)
