How to Machine Aluminum with ZMorph VX? 

Although aluminum is a great material to work with, we don’t recommend CNC milling in metals for beginners. That being said, there are no hidden obstacles while machining aluminum with ZMorph VX, and in this article we’ve prepared tips & tricks on milling in this type of metal. Feel free to contact us in the comment section below if you have any additional questions.

Voxelizer Settings 

CNC milling aluminum can be tricky and in the ZMorph Materials Library we’ve described it as difficult material. The Voxelizer settings will differ depending on your project, but there are few constants. We recommend:

  • Cutting speed: 1.5 mm/s
  • Lead in/out speed: 1.25 mm/s
  • Max. step down 0.15 mm.

Workpiece Holding

Use clamps to mount the material to the CNC worktable. Make sure the clamps are of good quality and won’t break when the machine is working. Aluminum is quite hard and you definitely don’t want loose parts flying away from your machine.

Remember that if your material is loose, your project will fail. Check some of our workpiece holding solutions and you’re good to go.

End Mills

It’s been proven by our engineers that you can successfully mill in aluminum with ZMorph universal end mills that are provided with the CNC Fun Pack and ZMorph VX Full Set. For some professional uses it’s recommended to purchase special end mills only for aluminum CNC machining. Otherwise universal flat or ball end mills are enough.

Aluminum Applications

Aluminum uses vary, but it’s mostly used for prototyping and end parts. The material can be also easily engraved on. Here are some photos of samples of aluminum machining with ZMorph VX.

Health & Safety

ZMorph VX operates on high speeds and it’s important to remember not to touch any moving parts while the machine is working. They are signed with special stickers for your safety.

Once again we remind you to double check if the aluminum sheet is properly mounted on the CNC worktable. Bad workpiece holding will result in failed machining attempt and also can damage your machine or even cause your injuries.
