Bearing asymmetry – the next level of drawing die management

both as easy to interpret numbers and as an intuitive illustration. This removes the subjectivity of the microscope inspection, and replaces it with consistent and repeatable measurements, all with the accuracy that has been a trademark for Conoptica for over 20 years.

breaks, oval cross-sections or deformed surfaces as a result. With the CU11 series of die measurement systems, Conoptica is providing a detailed view into the bearing of the die. With the unique Bearing Asymmetry 3D Analysis function, any variation and inclination of the bearing is displayed

EVEN today it is not uncommon to see a man or woman with a microscope and a set of gauge pins as the only means of die dimension control in die shops around the world. While the experience of these operators is valuable, their decisions when the bearing of the drawing die is concerned are subjective. When a die is chosen for a draw, it is assumed to have a symmetrical bearing – ideally a perfect cylinder. Most wire drawers and die shop managers have experienced that this is not always the case – often the hard way, with wire

Twisted fibre technology

Research published in the journal Nature Communications explains how a newly developed nanophotonic device, developed in Australia, could be used to upgrade existing networks. Researchers in the USA previously created a fibre that could twist light, but a team at Melbourne’s RMIT Univserity is the first to create a reasonably sized detector that can read the information, which could be used to upgrade fibre optic networks.
