However, in the second picture ovalization runout and the pupil is not due to any disease.

The special technique used in the making of the ring, gives concentricity without ovalization thus guaranteeing a uniform rotation.

ovality of the ropes or strands

The corrected diameters are then scrutinized to determine whether a mash or ovality condition is present and, where desirable, the bend radius of the pipe.

Measurement of diameter should be made in several points of each neck (both on length of a neck, and on its forming surface) is will help to reveal its ovality and a konusnost.

The surface finish is typically not as smooth as that for cold drawn wire and the diameter usually has a higher ovality than that for cold drawn wire.

In the case of the progressive press, only part of the forming cycle can be guided by spring loaded sleeves or similar, which result in concentricity and ovality issues and non uniform material thickness.
