Claim Text:
1. A method for micro/nano machining; the method comprising providing a turnable part carrying at one end a conical tip of material; said conical tip being polished down to a microscopic apex; seating, apex first, the conical tip in one end of a pivot aperture of a lathe head and concentric with said aperture such that the apex protrudes from the other end of the aperture to a position in close proximity with said aperture; retaining said lathe head in a micro/nano machining lathe system; axially rotating said turning part, including said conical tip seated in said aperture; and concurrently applying forward pressure to said axially rotating conical tip seated in said pivot aperture and in the direction of the aperture; whereby eccentric runout at the apex of said rotating conical tip is substantially minimized such that a pivot point of said protruding apex remains fixed for micro/nano machining of said apex.
