What are the two main functions of guards on cutting and grinding machines?

The primary functions of guards on cutting and grinding machines are fundamentally about safety and protection. Guards are designed to stop fragments from flying into the air, which is critical because when cutting or grinding, materials can break apart and become projectiles that pose a risk to operators and nearby workers. Additionally, guards serve to prevent the operator from coming into direct contact with the blade or wheel, significantly reducing the risk of serious injuries such as cuts, lacerations, or amputations.

In industrial environments, maintaining operator safety is paramount, and guards are essential safety features that adhere to this principle by providing a barrier between hazardous moving parts and personnel. The focus on preventing accidents through these protective measures is why this choice accurately captures the safeguarding role of machine guards.
