Development of Parallel Robot Cables by OKI Electric Cable
Use of high-flex robot cables on industrial machines such as factory automation is for their capability in supporting repetitive operation. In order to achieve this, usually a number of cables and air tubes are stored in the cable veyor. But this method requires wiring one cable at a time resulting in a poor productivity as well as leading to incorrect wiring with low bending performance. To over comes this issue each cable needed to be adhered but the use of durable and flexible adhesion in order to maintain the original sliding characteristics of the individual cable was difficult. In response to this issue, OKI Electric Cable announced the launch of VEYOR-CABLE (TM), a parallel robot cables which allows various high-flex robot cables to be combined and bonded to meet specific customer requirements. The VEYOR-CABLE can withstand more than 50 million bending cycles by incorporating an engineering plastic based elastomer adhesive for bridging bonding of cable sheaths resulting in the parallel configuration of cables that have different external diameters as well as air tubes, PCV-sheath cables and urethane cables made of different materials. The shipping of the new cable has already begun. The sales target for VEYOR-CABLE by March of 2010 is at 200 million yen.

[...] OKI Electric Cable has successfully developed OS-UZ Wire, a Zinc-plated wire for Wire-type EDM (Electrical Discharge Machine). The new wire features a unique four-layer structure for high-cutting speed and smooth cut surface. The aim in developing such wire was in fulfilling the needs of the metal parts and die & mold industries by improving manufacturing productivity, reduce wire consumption as well as cutting machine operation costs. The conventional method in improving cutting speed of Wire-type EDM is through use of heat diffusion wires, however, due to their complex structure it is more costly to use than brass wires. In addressing this issue OKI electric Cable utilizes a brass core which is covered with a zinc-rich brass layer, to which it applies a zinc layer as well as a thin special coating layer, resulting in a four-layer structure. The new OS-UZ Wire improves rough-cut speed by approximately 30% in comparison to conventional brass wires. The special coating will help against corrosion as well as improving its shelf life, and at the same time results in less metal powder adhesion problem in compared to brass wires. OKI Electric Cable has already begun its marketing OS-UZ Wire both in US and China and aiming for shipping target of 150 tons for fiscal 2010. source Share and Enjoy: [...]
