Plain cylindrical grinder Various motion required to grinding The machine is similar to center lathe. The work piece held between head stock & tail stock. Disc type grinding wheel perform grinding operation.

Transvers grinding Plunge grinding

Center-less grinder Center less grinding is the method when the work-piece is supported by a blade instead of by center or chuck. Two wheel used : larger wheel for grinding smaller wheel for regulate the axial movement of the work-piece.

Internal grinder machine These are used to finish straight , tapered or formed holes to correct size, shape and finish. Chucking grinder Planetary grinders Center-less grinder

Chucking grinder In this grinding process the work piece is chucked and rotate about its own axis to bring all parts of the bore or other surface to the ground in contact with grinding wheel. Chucking grinders are best applied whenever the work itself can be conveniently chucked and rotated.

Center-less internal grinder In internal centerless grinding the work is supported by three rolls. One is the regulating roll, and the other is a pressure roll to hold the work-piece firmly against the support and regulating rolls. The grinding wheel contacts the inside diameter of the work piece.
