What is a 3-Axis CNC?

3-axis machining is a widely-used way to make mechanical parts. There are 3-axis turning and milling machines. The turning type 3-axis are sometimes referred to as Vertical Turning Centers or Vertical Machining Centers, and the milling machines may be called Gantry Routers or Vertical Machining Centers as well. In a turning center, the machine operates as a lathe with a workpiece mounted within a collet, on the 3 axis milling machines, the workpiece sits on a table. Many 3-axis CNC milling machines actually are 4th axis capable.

Conventional machining tools, like a milling machine allow material to be worked on 3 axes.  In CNC milling, machines have the work piece fixed on the base of a machine and a tool that is moved until the edge cuts into the workpiece to remove material. When that machine cuts in the X, Y and Z special axes, it is considered a 3 axis machine.

A gantry router is a good example of a 3-axis CNC. This kind of CNC has a U-shaped hoop called a “gantry” that can be moved along a table’s Y axis. It carries another bracket that move perpendicular to the Gantry and carries a motor that can be adjusted up or down (on the Z axis.) Gantry style 3 axis CNC’s allow for machining of larger workpieces, but they have greater deflection. The machining tool removes shavings in the three directions corresponding to the axis of a flat surface. It’s good for parts that are not too deep or have narrow cavities. Though long, skinny tools can make deep-cavity molds, for example, it’s more likely to have tools chattering, breaking and producing a lower quality surface finish with 3-axis machining.

3-Axis Lathe

A 3 axis CNC lathe can machine curves with the workpiece held in place by collets. A turret holds the tools and is programed to move to the workpiece which turns. Some machines have multiple tool positions and live-tool pockets on the turret which add additional functionality. Others may have a dedicated milling too driver on the turret face. Some manufactures mount an independent milling head with tool change capability.

Turning a 3-Axis CNC Milling Machine into a 4-Axis CNC Milling Machine

CNC machines exist with as many as 15 separate axes, and the more that are available, the more complex the parts that are possible. Often a 3 axis CNC machine for sale can be upgraded to add a fourth axis to give access to all sides and the bottom of the workpiece. For example, when a rotating machine table is added the combination of rotation and vertical movement, it can be used to mill threaded parts. Keep in mind that it requires much more complex programing to effectively use a rotary table with your 3 axis CNC milling machine. You’ll need CAM software to create the program for your CNC. If you are looking for a milling machine, but don’t need the 4th axis right now for your parts, it may still make sense for you to buy a used 3 axis CNC equipped with the extra 4th axis. It could be something that you’ll want to do in the future and not cost you much more. You’ll typically see the “4th Axis” somewhere in the description of an otherwise standard 3 axis CNC.

Companies that make (or have made) 3-Axis CNC machines include Hurco, Samsung, Haas, DMG/Mori Seiki, Doosan/Daewoo, Fadal, Makino and many others.

Have You Found a Used 3-Axis CNC lathes that Looks Interesting? Here’s what you can do before you go see it.

  • Be informed. When shopping for a used 3 Axis CNC, you’re going to need to do more research than when buying a new one. It might help to make a list of your requirements. This can help you determine what age 3 axis CNC lathes works best for your shop. You may want to buy a similar year or model to a 3 axis that you already have, or you may want to look newer 3 axis CNC lathes, so you can begin to connect everything via ethernet or Wi-Fi to take advantage of software innovations.
  • Ask for good photos. Zoom up in the photos and look for signs of damage and worn components.
  • Speak with a local 3-axis service provider who can provide service for the machine. Get his/her opinion on any specific machine type that you are considering purchasing.
  • Search similar years for the 3-axis model to see how pricing compares.
  • Get the hours of operation.
  • Ask for the maintenance records of the specific 3-axis that you are considering. Repair work isn’t a bad thing, in many cases it will help you know what been replaced, what hasn’t and if it was done right. Ask for as much documentation as the seller can provide.
  • Find out if any tooling or other accessories are being offered for sale along with this 3-axis CNC.

Once you’ve done your homework, and you think you’ve finally identified the perfect 3 axis CNC for your company, you may decide to buy it without looking at it, or you want to go the extra mile an inspect the machine for yourself. Here are some inspection tips below so that you can get the best used 3 axis CNC for the price. You can also visit Finding the Right CNC Machine for Sale for more information.

How to Inspect a Used 3 Axis CNC lathes for Sale On-Site

  • Inspect for damage and worn components. Carefully look all over the machine. A good used 3 axis for sale should little wear, since they are built to last for years.
  • Ask to operate the machine to see it actually run.
  • 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. See how well it changes tools at different areas of the tool changer
  • 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. For older machines, the processor may have been upgraded.
  • For lathes, review bar feeder options (does one come with the machine?)
  • Review chip & coolant management options.
  • Find out the electrical requirements for install.
  • Discuss payment options, you may get a better deal with a cash down-payment.
  • Buy from someone who has a good reputation.
