What is the minimum clearance that should be set on a bench grinder for safety?

• A. 1 mm
• B. 2 mm
• C. 3 mm
• D. 4 mm

Answer: (C)

The minimum clearance that should be set on a bench grinder for safety is 3 mm. This clearance is critical as it ensures that the grinding wheel does not come into contact with the workpiece without an appropriate amount of space. A gap of 3 mm minimizes the risk of the grinder wheel binding or catching on the workpiece, which could lead to dangerous situations, including injury or damage to the equipment. Ensuring proper clearance also allows for the effective removal of material while maintaining control and stability during operation. Furthermore, this distance helps to reduce the likelihood of overheating the workpiece and minimizes the generation of sparks, which can pose fire hazards. In professional settings, such standards are important for ensuring both user safety and the quality of the work performed.
