Total Chip Protection for Machine Tools

EAST PROVIDENCE, R.I. – Metal chips can cause abrasion and wear in long travel, gliding cable carrier applications. To combat this, igus® has developed a horizontal guiding system called “Guidelok”, which is designed to keep the upper and lower cable carrier runs apart. The new solution is ideal for applications in the machine tool industry up to 164 feet.

Debris and chips can become trapped between a cable carrier’s upper and lower runs as they glide on top of one another. Guidelok’s design keeps the upper and lower runs separate via a spring-loaded roller support, which is pushed back as the cable carrier passes through, before snapping out again after the radius has passed. The upper run rests on the roller support and is not allowed to glide on the lower run.

The system not only works to reduce abrasion and wear caused by trapped chips and debris, but also offers a number of other advantages. The system means the cable carrier can support itself over a longer distance. This enables users to choose a smaller version for the given length, saving overall costs and reducing the required push-/pull driving force. Guidelok keeps the upper and lower runs of the cable carrier separate from one another, which helps to minimize friction and wear and thereby increases service life.

The horizontal Guidelok system is already being used successfully by one machine-tool manufacturer, who replaced a heavy steel chain with this solution. A more traditional solution would have allowed large metal chips to settle in the inner radius between the upper and lower runs of the cable carrier, which could have caused damage. In contrast, the new system is ideal for such applications. Guidelok is also lower cost than most steel chains or sophisticated gliding systems.

New Guidelok is designed to be modular—the side troughs are optional—and is currently available from igus North America with a three week lead time. A movie illustrating the new design can be found at www.igus.com/ApplicationCorner/ec_videos.asp. Alternatively, call 1-800-521-2747 or e-mail sales@igus.com for more information.

ESD Cable Carriers from KABELSCHLEPP

When manufacturing and processing electronic components, electrostatic discharge (ESD = ElectroStatic Discharge) presents a serious hazard for the sensitive electronics. In addition, the increasing miniaturization of semiconductor components means even greater sensitivity to ESD.

Even More Conductive! ESD cable carriers satisfy tomorrow´s requirements. Thanks to the new
ESD material KABELSCHLEPP cable carriers are now even more conductive and with a surface resistivity of ≤
105 ohms surpass by far the requirements contained in the ESD standard (DIN EN 61340)

Improved protection against electrostatic discharge is thus necessary for not only for the materials and tools used, but also for cable carriers However this can be achieved during handling and assembly only if the plastic cable carriers used have an even lower surface or volume resistivity.

To provide this, KABELSCHLEPP is relying on nanotechnology. The material used in the new ESD cable carriers incorporates carbon nanotubes (Baytubes® from Bayer MaterialScience). Carbon nanotubes are microscopically small tubular particles made of carbon. The carbon at-oms form a honeycomb-like structure. The electrical conductivity of such nanotubes is deter-mined by the details of this structure. The electrical conductivity is increased thanks to the graphite structure on the surface of the material created by the carbon nanotubes as a func-tional additive. So much for theory.

For the real world, this means: The new ESD cable carriers from KABELSCHLEPP are now even more conductive and with a surface resistivity of ≤ 105 ohms surpass by far the require-ments contained in the ESD standard (DIN EN 61340). Thanks to the large specific surface and the extremely even distribution of the carbon nanotubes in the carrier material, good conductiv-ity is also achieved at the contact points between the chain links and thus over the entire length of the carrier.

Additional benefits: As a consequence of modifying the fiber-reinforced material with nano-tubes, the stability of the cable carriers increases as well.

Whether in chip manufacturing, semiconductor production, manufacturing of electronic components or solar engineering, thanks to their low surface resistivity, the new ESD cable carriers from KABELSCHLEPP not only significantly reduce the risk of ESD, but also represent a useful investment with respect to future standards.

RX Energy Tube from igus

EAST PROVIDENCE, R.I. – igus® has now developed an energy tube especially for the machine-tool industry that is almost 100 percent chip-proof. The airtight, fully enclosed cable carrier ensures all debris simply falls off.

igus® is using the FABTECH show in November to launch the new-style “RX” energy tube, which has a specially designed, smooth domed exterior onto which debris—such as metal or wood chips—can not attach itself. Connecting parts are concealed on the interior to facilitate this. Comprehensive tests—including underwater experiments—have been carried out in igus®’ test laboratories which confirm the new energy tube is 100 percent airtight.

Despite this, the RX energy tube can be easily opened using a screwdriver to unscrew bolts integrated into the outer radius of each link. There is also a very large interior space for cables and hoses, which can be separated using vertical separators, and a horizontal shelf to safely route cables and hoses and thereby prevent abrasion. Both these features mean maintenance and machine downtimes are reduced to a minimum.

The new energy tube is well suited to short, self-supporting lengths inside tooling machines. The chip-proof cable carrier was also developed to be used in reverse bending radius (RBR) applications. The RX energy tube is available in a high-temperature version, made from the special, high-temperature material “igumid HT”. This version ensures that even red-hot chips up to 1,562 degrees Fahrenheit fall off the tube rather than melt onto it. The enclosed cable carriers can also be delivered as pre-assembled ReadyChains®; ready harnessed with cables, hoses, and internal separators, as required by the customer.

igus’ Rol-E-Chain Cable Carriers

EAST PROVIDENCE, R.I. – igus®’ Rol-E-Chain cable carriers have a unique design: built-in wheels to facilitate travel over long distances, such as on a crane. The wheels are integrated into the cable carrier’s side links and reduce friction dramatically, which makes longer travel, heavier load and faster speed applications possible.

The upper portion of a conventional cable carrier glides on the lower portion over longer distances. However, requirements for cable carriers in long travels have been increasing in recent years. Travels over thousands of feet present new challenges in crane construction, as do high travel speeds and cable loads up to 33.6 pounds per foot. As length of travel, load and speed increases, so does friction, which can lead to premature wear and load problems for a cable carrier.

This new-found need to expand the technical limits of cable carriers was behind the development of Rol-E-Chain. With its unique design, friction is decreased and travels over 2,600 feet are achieved easily at speeds up to 32.8 feet per second. Moreover, the drive power required to move the cable carrier is reduced by more than 25%. Rol-E-Chain is also resistant to applications involving harsh environmental conditions, such as thick dirt.

The cable-carrier design is ideal for applications on cranes, material handling devices, plasma cutters and high-speed transfer systems.

New Cable Carrier for Cranes

EAST PROVIDENCE, R.I. – igus® has now launched a completely new generation of roller cable carriers. New “System P4″ was unveiled in the States at the IMTS show in September and is available on request. The new cable carrier has achieved speeds up to 23 feet per second over distances of 400 feet in igus’ outdoor testing facility. P4 is specially developed for indoor and outdoor cranes, as well as conveyor systems.

The need for ever-increasing speeds demands advancements in cable carrier technology. Similarly, cable carriers must operate smoothly and quietly because many ports are expanding and moving closer to residential areas. P4 is especially low noise and wear resistant at high speeds, even with loads up to 20 lbs/ft. In fact, thanks to the use of additional center links, there is practically no weight limit. Each link has the same short pitch, which means the cable carrier moves with minimal vibration in its radius. Plastic bridges and grooves along the surface of the cable carrier —a design from igus for long travels called ‘AUTO-GLIDE’ —mean the upper run of the P4 chain glides smoothly over the lower run.
The plastic rollers are firmly integrated into the sides of the cable carrier and do not rotate over one another, because the cable carrier’s upper and lower runs offset. This reduces wear and increases service life.
