Automated drilling machines usually provide fast and accurate holes, that is until the drill bit breaks. The last thing a high production furniture manufacturer wanted to do is to keep drilling parts with one hole missing! NK Technologies’ Current Operated Switches were installed over the current carrying conductor feeding the drill motor and when the amperage dropped below a preset level a signal was sent to the controller to stop operation so that the drill bit could be changed. NK’s range of current transducers are used in a variety of applications on machine tools to detect status.
