What does it do? How can I use it? Why will it help me?
A cylindrical grinder is a specialized form of grinder meant for work on cylinders, rods, and other similar workpieces. The cylinder rests between two centers and rotates in one direction, while the grinding wheel or wheels approach and rotate in the opposite direction. In this way, a cylindrical grinder works much like a lathe would, except instead of a stationary cutting tool, a grinding wheel is used.
In addition to rotating the workpiece rapidly in opposition to the grinding wheel, both the wheel and the table on which the workpiece rests undergo various movements. The grinding wheel may move up and down or side to side, while the table moves back and forth. Cylindrical grinding is incredibly precise and provides an excellent final finish.
Centerless grinding is considered a subset of cylindrical grinding.

Process Description: How does it work?
A cylindrical grinder consists of four parts: the head and tail stocks, the grinding wheel, the wheelhead, and the table. Some grinders can be computer controlled or have multiple wheels.
The workpiece is held between the headstock and tailstock, exactly as it would be on a lathe. The workpiece is rotated rapidly between the centers. The grinding wheel, which does the actual grinding by rotating at a different speed from the workpiece in the opposite direction, is attached to the wheelhead, which moves the grinder in various patterns such as plunge or traverse motions. At the same time, the table also moves laterally.
