Abstract
Electro-chemical polishing of fine wire contacts is facilitated by welding the wire contacts to a mounting element on a continuous, flexible, metal strip. The assembled contact strip is wound on a spool and transported to the electro-chemical polishing site where the contact strip is drawn into the polishing site at a constant rate under the control of a microprocessor. The progress of the assembled contact strip is monitored by metering rollers and pulse generators that inform the microprocessor of the drive speed of the assembled contact strip. The controller then provides signals to control the take-up and supply spools to ensure that a proper tip polishing operation is carried out.
