Flexible ring rolling

ring-rolling-machineThis machine has 11 degrees of freedom and is probably the world’s most flexible ring rolling machine. It deforms plasticene rings of around 120mm diameter through two roll bites, each of which comprises an outer forming roll, and two other rolls which can move with two degrees of freedom each relative to the forming roll. The two forming rolls move outwards together, so the centre of the deforming ring remains stationary. The design of the machine is described here, and it has been built to explore a wide range of machine configurations with the aim of achieving nearer net shape production of low volume high value rings.
