🔍 Key Concepts

• Function of truing vs. sharpening or polishing a grinding wheel • Common shop tools specifically designed for maintaining grinding wheels • Safety and accuracy requirements when using a grinding wheel in a machine shop

💭 Think About

• Which of these choices is purpose-built to restore the grinding wheel’s shape and surface, rather than remove material from a workpiece? • Think about which tool would contact the abrasive wheel safely and evenly across its face. • Which option would most likely be found stored right next to a bench grinder in a maintenance shop?

✅ Before You Answer

• Be clear on the difference between cutting tools for metal and tools for maintaining the wheel itself. • Ask: which of these is designed to restore the wheel’s roundness and expose fresh abrasive? • Eliminate any option that would be unsafe or ineffective to press against a rapidly spinning grinding wheel.
