What is a wheel dresser?
A wheel dresser, also known as a dressing tool, is a tool or device used to dress or reshape the abrasive particles on the surface of a grinding wheel. The purpose of dressing a wheel is to restore its cutting ability and create a uniform surface on the wheel. This ensures that the wheel cuts consistently, reduces chatter and vibration and increases the wheel's lifespan. Wheel dressers come in a variety of types and designs, each suited for specific types of grinding wheels and machines. The most common types of wheel dressers are: 1- Single-point diamond dressers: These are used to create a specific shape on the wheel, and are typically used for precision grinding operations. 2- Multi-point diamond roll dressers: These are used to true the wheel surface and are typically used for heavy-duty grinding operations. 3- Stick or star dressers: These are made of tungsten carbide or steel and are used to true and maintain the shape of the wheel.
