Changing the way of wire drawing

Ajex & Turner is using vitrified nanocrystalline technology that has changed the traditional way of wire drawing. The prospects of this technology will, the company believes, have a huge impact in the future and will save material and manufacturing costs for cable companies. Its research and development team has developed diamond coated dies and extrusion tooling for bunching and compacting copper and aluminium multi-wire strands for electric cables. These dies are made with multi-layer coatings of nanocrystalline diamond composites on tungsten carbide nibs, which provide a smooth surface with low friction. This technology provides a much harder and compact surface in comparison to PCD, and the company is developing a process to re-size and re-polish from 29mm to 42mm. There are numerous advantages over PCD. The layer of diamond is 100 per cent diamond and resistant to wear, unlike

The machine model TCD-10 will keep you ahead in the area of die polishing and grinding as it does both of these in one operation, saving time and energy, and increasing cost effectiveness. The machine operates at high speed and can recondition dies in a short period of time. It is also possible to achieve a mirror polish using diamond suspension and steel pins. started manufacturing wire drawing lubricants for copper and aluminium for fine wire and RBD, in association with a UK-based company.

PCD which is a mixture of cobalt and other hard materials.

This gives a cost-saving on repolishing, with tolerance remaining the same. The cost of the new dies is also four to five times less than PCD, and can be recut in microns. Ajex and Turner’s R & D is working to increase the layers of coatings, which may also help coating profile dies and increase the working life of the die by a further 30 to 50 per cent. The size range is 2.5mm to 42mm, while the reduction angle is generally 18 to 24 degrees with 20 to 30 per cent bearing length.

Easy migration from Corning Providing a simple and cost-effective migration to 40G and 100G, the Pretium EDGE AO solution from Corning improves infrastructure ROI by 30-50 per cent and speeds up installation by 35 per cent. It also offers the ability to support quick and easy migration to parallel optics for datacentres and SANs, while its integrated port tap module enables non-disruptive monitoring of higher speed connections. The Corning Pretium EDGE AO solution enables the next level of performance in datacentres and SANs, while providing unequalled rack density, improved airflows, ease of access, quick deployment and simpler moves, adds and changes (MACs).

Enhancements include:

• Simple swap outs of modules and harnesses • Leaves hardware and trunk cables in place • Maintains 100 per cent fibre utilisation

• Full management of link polarity with the ability for easy onsite changes • Integrated port monitoring with passive optical splitters for 10G, 40G and 100G • No increase in rack space Corning Inc – USA Website : www.corning.com
