The FABtotum’s Milling Head add-on is made for Engraving, Milling and Cutting many common materials.
Why using a CNC machine? What is it used for?
A CNC milling machine is useful to create 2D and 3D objects with high precision. This kind of device is used in big sizes for industrial mass production. A smaller version, like the FABtotum’s is perfect to fit the gap between big and small companies. This tool is perfect when the need of rapid prototyping with a different material arises. While 3D printing can rarely (as for today) create something different from plastic, a milling tool can cut off or engrave many materials such as cardboard, foams, woods, metals or even PCBs. The result will be of an higher precision compared to additive manufacturing and the surface will be smooth.
A CNC machine on a desktop can be of great help for many areas of interest: from architecture to design, from dental and medical to toys and customization.
Modeling foams can be of many kind (see CNC and Rapid Prototyping Materials) and can provide great results for scaled landscapes and human body parts; woods and metals might help when reproducing buildings, tools, plates and toys. Milling PCB without using chemicals is just a quicker and safer way to develop new projects. If you wish to know more about different choices, read the dedicated Materials page.
The hardest part is choosing the right bit. There are thousands of choices.
How to choose the best milling bit?
The Milling Head uses standard ER8 collets and 1/8th inch bits (3.175 mm).
You may choose the best milling bit depending on the final goal and the material used.
See the “Parts and Accessories” and Materials for Subtractive Rapid Prototyping for more details on the different surfaces. The ones that can be used on a FABtotum are “end mills”, as they must be used with the provided ER-8 chuck. Among this category, a wide range of possibility is still available to better choose the right tool.
Here are a few examples:
