Ravni‘s MDC40 straightening and cutting machine

▲

All machine functions can be found on the user-friendly control panel, which displays the di erent stages of the production process. As with all Ravni Technologies models, the machines are tted with a fast tool changer. The preset straightening tools save time and avoid waste wire at each diameter change. The Ravni range also includes tube cut-o machines, chamfering and deburring machines, shaped wire straightening and cutting machines, and slot screen welding machines for the ltration industry. The company also provides tailor-made solutions according to customers’ speci cations. Ravni supplies its machines all over the world; around 70 per cent of turnover is exported, and the company is still enlarging its network of agents. Ravni Technologies www.ravni.com For wire, diamond-based materials are state of the art, but there is a distinction between tools using polycrystalline diamonds and tools with monocrystalline diamonds. Using optical microscopy to inspect a polished polycrystalline diamond (PCD) yields a perfectly smooth surface, but SEM-micrographs reveal the granular structure of the material). This is to be expected, as PCD is made from diamond powder – microscopically small monocrystalline grains of diamond that are sintered into a die in a process involving a catalyst (eg cobalt) at temperatures around 1,400°C and pressures of 60 kbar. The result is a contiguous structure of interconnected monocrystalline diamond-grains, the PCD. Diamond consists of cubically arranged carbon atoms, a material with directional physical properties (anisotropy). Directional di erences of hardness in diamonds have been measured to have a ratio of 1:9. drawing ne copper Redies Stand: 09 B25

RSL 1400 model

The single-furnace multi-chamber design accurately controls and maintains the target composition by varying the feed rate of each of the constituent elements. The liquid metal is protected from the atmosphere by being enclosed within an argon gas environment. Rautomead will also be exhibiting its conventional open furnace model continuous casting machines, which are used for the production of high-purity, high-quality oxygen-free copper wire rods and also conductor alloy rods such as CuMg, CuAg and CuSn. This continuous cast rod material bene ts manufacturers of enamelled wires, super ne wires, LAN cables, wiring harnesses, railway wires, shaped, contact wires, CTC and transformer strips. the production of 1,000 to 12,000 tonnes per year in the diameter range 8 to 30mm. Sample coils can be manufactured to order and produced on the continuous casting equipment installed at the Rautomead facility in Dundee, UK. Rautomead Ltd www.rautomead.com Equipment is available for French Company Ravni Technologies will show its powerful and e cient wire straightening and cutting machines, MDC20 (for 2-6mm wire) and MDC40 (4-12mm). A new servo cutting device has been integrated on all of the range. Feeders and straightener are also equipped with new-generation motors, and are more compact, energy e cient and exible to use, as well as being quieter. Ravni Technologies Stand: 10 B12
