Thread: Machining Cork |
02/04/2016 18:54:41 |
I recently found myself needing to cut some cork into a cone shape, and after attempting to cut it down with a razor sharp knife, I discovered the best way was simply to chuck it in the lathe and, using a normal right-hand knife carbide tipped tool, machine it down with the speed set at the highest. In my case this was around 2650 rpm, this provided quite satisfactory results with all types of cork, reconstituted ones included. For boring this also works, however as the bit gets smaller the speed needs to increase (obviously) so as to maintain high speeds at the cutting edge, and beyond some diameters this becomes hard to achieve. As a suggestion if this is the case, perhaps a power drill mounted in some fashion on the tailstock could spin in the opposite direction to the lathe chuck so as to increase the relative speeds between the bit and the work? |
