Rockford Systems Inc. has introduced a new line of electrically interlocked, heavy-duty drill shields. They are available for small to large drill presses and similar machines.
When the shield is swung out of position, the positive contacts on the microswitch open, sending a stop signal to the machine control. The safety microswitch is mounted in an enclosed housing with a rating of IP 67, and each switch has a mechanical life of 1 million switching cycles.
The high-impact-resistant, transparent polycarbonate, semioctagonal front shield provides operator protection from flying chips and coolant. The adjustable shield clamps to a steel support rod that rotates 180 degrees and operates the shield safety microswitch.
