How Grinders Work

Grinders operate by rotating a disc or wheel at high speeds, which applies friction to the material being worked on. This friction generates heat and abrasion, allowing the grinder to cut or grind through the material effectively.

Key Components of a Grinder

  • Motor: Provides the power to rotate the grinding disc.
  • Grinding Disc/Wheel: The abrasive surface that makes contact with the material.
  • Handle: Allows the user to control and maneuver the grinder.
  • Safety Guard: Protects the user from debris and sparks during operation.
