The automatic chainsaw sharpener is a device that uses an abrasive wheel to sharpen the chain of a chainsaw. The machine can be used by anyone with little or no training and it is also very easy to use. The process of sharpening the chain of a chainsaw starts with the user placing their blade on the wheel and turning it by hand. The wheel will then rotate, rotating faster as it gets closer to the edge. The wheel will then be stopped when it reaches its peak speed, which will cause one side of the blade to become sharper than the other side.
