Rojone has introduced a new CNC bending machine into its manufacturing set-up to significantly increase its capability to produce volume, state-of-the-art semi-rigid cable assemblies and delay lines suitable for microwave, military, RF, and telecommunications applications to 18GHz.
Rojone is one of Australia’s leading coaxial cable assembly manufacturers for over 30 years.
Rojone’s new RD5 CNC bender produces 3 axis bends with high speed, accuracy and repeatability directly from the customer’s CAD or STEP files, using the full range of qualified Mil-C17 semi-rigid coax cables.
The RD5 bends semi-rigid cable using a rotary wipe process. This technique has proven to be the gentlest of bending techniques on the semi-rigid cable allowing excellent signal transmission when the cable is in its final assembly. The collet closer that holds the coax during the bending process is designed specifically to grip while being gentle on the cables outside the jacket. The design of the carriage spindle allows the end of the coax cable to get right up next to the bend tooling on the very last bend, avoiding a trimming operation after bending.
Semi-rigid coax cable assemblies are typically used in ground and airborne radar systems, satellite and terrestrial wireless communications equipment, high bandwidth data communication equipment, medical imaging apparatus, test equipment, electronic warfare and connecting to microwave antennas. These applications require excellent durability, phase stable performance, low attenuation, high signal fidelity and the ability to handle more power.
Semi-rigid coax meets these requirements and is ideal for high temperature, high power applications while maintaining excellent phase stable performance and minimising VSWR. Semi-rigid is especially significant in tactical environments where high shielding and shock or vibration tolerance is critical.
Rojone offers their clients complete design, drafting and prototyping assistance for any prospective assembly requirement.
