What is Machining Wax?

Machining wax is a term for an exceptionally hard synthetic wax mixed with plastic that features great machining properties, quality of finish, and dimensional accuracy. The material is recyclable and reusable, and is used to produce accurate molds, prototypes, and jewelry.

How to CNC Mill in Machining Wax?

Machining wax is believed to be an easy material for CNC machining (hence the name). Below you’ll find practical tips & tricks on how to mill in machining wax with ZMorph VX.

Voxelizer Settings

Based on our internal testing, the following settings should deliver the best results:

Cutting speed – 1.75 mm/s
Lead in/out speed – 1.25 mm/s
Max. step down – 0.15 mm

Workpiece Holding

We recommend using double-sided foam tape to secure the material on the CNC worktable. Alternatively, you can use clamps but be careful while fastening the mount. Although machining wax is a relatively hard synthetic material, you can dent the sides by placing the clamps too tight.

End Mills

While CNC milling in machining wax you can use universal single flute end mills.

Other

Machining wax can clog the end mill, that’s why it’s important to vacuum the inside of the machine while doing big projects. We recommend also closing the covers of ZMorph VX.

Machining Wax Applications

Due to its features, machining wax is widely used for casting cores, molds, and CNC program proofs

Health & Safety

Although CNC milling doesn’t generate as many fumes as 3D printing, you should still take care of proper ventilation while working. The machine can generate some noise that is not dangerous to hearing but can be fatiguing. Consider using ear protection or leaving the room while ZMorph VX is CNC machining. If you choose to leave the room, make sure no one unskilled is around the machine, and check on it from time to time.

Do not, under any circumstances, touch the moving parts of the machine while it’s operating. You’re risking serious injuries while doing so. Additionally, make sure no loose part of clothing or long hair gets sucked into the device.
