So, under another thread I had an epic adventure of fixing up an old 3040 CNC engraving machine with an enclosure. It is an air cooled spindle with no coolant. Now I am thinking of all the projects I can accomplish with the machine and one of them is to cut a simple watch case out of 316L. In your opinion and experience, given the right selection of cutters/ feed/ speed, it is even remotely possible to do?

If not, I will not venture down this road but if it then I will try all avenues and break as many cutters as financially possible to achieve this feat. All advise is appreciated.
