Interlocking shields

Rockford Systems, Inc.’s new line of electrically interlocked heavy-duty machine shields are available for vertical milling machines and have two safety microswitch locations. When the shield is swung out of position at either safety microswitch location, the positive contacts on the microswitch open, sending a stop signal to the machine control. All safety microswitches are mounted in an enclosed housing with a rating of IP 67 and a mechanical life of one million switching cycles. The shields consist of a thermo-formed, high impact-resistant, transparent polycarbonate front shield in tubular-steel frames. This provides operator protection from flying chips and coolant. The shield clamps to a steel support rod that rotates 180 degrees and operates a shield safety microswitch. The steel base also houses a second safety microswitch and provides lateral adjustment. Each shield can be positioned for maximum protection during operation and can be swung out of the way for easy access to the workpiece and tooling.
