While most turning, grinding, and milling machines are designed for safety, they are not failproof. CNC machine fires cause significant loss to life, limb, and property every year. These fires could result from excessive heat, tool failure, programming mistakes, a drop in oil level, and any other anomaly. When left unchecked, such fires can spread quickly and envelope other equipment or even the entire facility. In contrast, the timely detection of fires and suppressing them right at the start can protect the equipment, building, and lives.
