Ultra’s ingenuity overcomes workholding problem
We were recently asked to machine a part for a customer which was a long Aluminium cone, with four deep slots milled along the whole length.
We opted to produce this on one of our CNC Turning / CNC milling centres. The original idea was to pick off the part holding on the cone using extended jaws. We had our concern with this method, which proved to be founded, when the jaws ‘spitted’ the part out as the taper on the cone proved too steep.
Our head engineer then resorted to his plan B, which was to use wrap around jaws, and mill within these four teeth with clearance to allow it to pick off the part holding onto the bottom of the slots. This proved to be very successful and the part was produced.
