Our milling machine is a 3-axis CNC milling machine, i.e. the model can only be approached from one side at a time. A bangle is milled from 2 sides, so an undercut model is not possible.
Many materials can be milled, such as wood, horn, wax, various plastics, HPL, GRP, CFRP, etc. Unfortunately, metals are not possible except for aluminium and automatic steel.
here are a few impressions:

in order to keep the milling time and thus the costs low, it has proven itself not to mill wooden bangles too fine - the steps have a maximum thickness of 0.1mm and can therefore be easily smoothed out by hand
