Non-contact in-line measuring systems for diameter and roundness

For rod bar and tubes.
For finishing, peeling, grinding, straightening, quality control (NDT).

DIAROND is a novel, non-contact measuring system from Zumbach. It allows to measure, simultaneously the diameter and the roundness of cold processed steel products in the production or testing line.

The problem
So far, a measurement of roundness and shape deviation can be done only on samples by means of tactile laboratory-measuring machines (e.g. MAHR, MITUTOYO, TAYLOR HOBSON etc) but not continuously in the production line.
Conventional optical in-line gauges, allow for accurate measurement of diameter and limited capability for ovality, but no possibility for roundness or shape.

The solution
A high-precision, 3-axes laser head ODAC® TRIO measures at high frequency and fully synchronized, 3 x diameters at 60° offset to each other, and 6 x corresponding tangent points on the periphery of the product. All measured values are stored in the USYS IPC processor. For completing the whole profile there must be a self rotation of the product of at least 60° or a rotation of the measuring head by means of a rotary device. An angle information is not required. Without rotation, there can also be statistical evaluation of a number of parts, where
results can be enhanced by any random manual oscillation or orientation.
