Rockford Systems Inc. has introduced a new line of electrically interlocked heavy-duty drill shields. The use of these electrically interlocked drill shields goes beyond OSHA and ANSI safety requirements.
These electrically interlocked shields 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 one million switching cycles.
The shields consist of a high impact-resistant, transparent polycarbonate semi-octagonal front shield that 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.

Fluid that reduces temperature buildup at the tool/workpiece interface during machining. Normally takes the form of a liquid such as soluble or chemical mixtures (semisynthetic, synthetic) but can be pressurized air or other gas. Because of water’s ability to absorb great quantities of heat, it is widely used as a coolant and vehicle for various cutting compounds, with the water-to-compound ratio varying with the machining task.
