We have been using a CNC for inlay for a few years now and are starting to play with carvings. How do you remove the tool marks and finish a CNC carving? I have thought of playing with a fladder sander head on a hand held spindle or a Nylox brush. I use a very small stepover with a 1/8" ball mill but still think sanding or something is required to get a good look. Any suggestions?
From contributor M:
Try an Onsrud taper ball, they are much stiffer and leave less marks than a small straight bit. I am usually profiling and carving with about 1/1000 max error which doesn’t leave much to sand, but really I think hand sanding is best. For all the machine time it takes to do this kind of thing the hand sanding preserves the nice details and takes much less time than the machining itself. Other than sanding sponges from 3M and etc I know of no other really good way to preserve detail.
