What is the purpose of a grinder?
Grinding and Polishing Metal
The primary purpose of an angle grinder is to grind metal. It achieves this with the use of abrasive grinding discs that come in a range of materials, like aluminum, carbide, and diamond-tipped discs. Attach a grinding disc and turn on the grinder to start the disc spinning rapidly.
What is the principle of grinder?
A grinding machine uses an abrasive product — usually a rotating wheel — to shape and finish a workpiece by removing metal and generating a surface within a given tolerance. A grinding wheel is made with abrasive grains bonded together. Each grain acts as a cutting tool, removing tiny chips from the workpiece.

Wet grinding describes a grinding process under addition of water, emulsion or oil. The main tasks of wet grinding are: cooling and lubricating the processed surface. cleaning (removal of the grinding chip) protecting the tool against corrosion.
How do you use grinding tools?
Lift the grinder from the edge, switch it on and let it come to speed before moving it into the blade. Stroke the grinder across the work in the direction of the handle rather than grinding back and forth. Then lift it off and repeat, concentrating on holding the grinder at a consistent angle throughout the stroke.
