Rockford Systems Inc. has introduced a new line of electrically interlocked heavy-duty grinder and tool grinder shields. The use of these electrically interlocked grinder shields goes beyond OSHA and ANSI safety requirements, according to the company.

These electrically interlocked shields are ideal for single- and double-wheel grinders. 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 electrical wires are furnished with a protective sheath and connect to the safety circuit of the machine that switches off the control to the movement of the grinding wheel. All safety microswitches are mounted in an enclosed housing with a rating of IP 67.

Each shield consists of a high impact-resistant, transparent polycarbonate shield with an aluminum profile support and provides operator protection from flying chips and coolant. The shields have horizontal and vertical adjustment with a steel arm that provides easy mounting.
