In thrufeed centerless OD grinding the workpiece passes between two wheels, a grinding wheel and a regulating wheel (as illustrated in the diagram, right). Both wheels rotate in the same direction, but at much different speeds. The purpose of the grinding wheel is to remove material from the workpiece and improve part OD quality.
Centerless Grinding. Centerless grinding is an OD grinding process. It differs from other cylindrical processes in that the workpiece is not mechanically constrained. On traditional OD machines, the work is held between centers or chucked and rotated against the faster spinning grinding wheel by an external motor usually located in a workhead.
In-feed centerless grinding is used to grind workpieces with relatively complex shapes, such as a shoulder bolt. It is typically faster and more economical than multi-step grinding processes. Benefits. Higher quality surface finishes and precise OD tolerances for entire bar .

Centerless grinding results in close tolerances but only if the machine is properly set up for the operation. After taking this class, users will be able to describe the steps required to set up a centerless grinder for routine OD grinding of a cylindrical part.
These centerless grinding machines are ideal for creating a polished or satin finish on tubes or removing mill scale prior to welding.
In centerless grinding, the workpiece is held between two grinding wheels, rotating in the same direction at different speeds.One grinding wheel is on a fixed axis and rotates so that the force applied to the workpiece is directed downward. This wheel usually performs the grinding action by having a higher linear speed than the workpiece at the point of contact.
But centerless grinding doesn't have to be misunderstood. "You have to de-velop the skill level for centerless and then it becomes a day in, day out oper-ation," said Mark Schram, president of Ace Grinding, Melrose Park, Ill., a cus-tom centerless grinding shop. "It's not really a difficult thing to do." Centerless Basics
Centerless Grinding. Centerless grinding is an abrasive process that removes material and renders a specific finish to the outside diameter of tight tolerance, small cylindrical metal parts. The process can be used to improve the surface finish of parts that were previously machined (turned).
