Centerless grinding is an abrasive cutting process to remove material from a workpiece. Similar to centered grinding except without a spindle. This method is favored by high volume operations because parts can be quickly inserted and removed from the process. High volume, high quality grinding is quickly becoming a lost art.

Centerless grinders are everywhere these days. You can find them in shops that specialize in centerless grinding, outfits that combine centerless grinding and machining and even factories that incorporate a centerless grinder into a broader manufacturing process.
The larger grinding wheel does grinding, while the smaller regulating wheel, which is tilted at an angle, regulates the velocity of the axial movement of the work- piece. Center less grinding can also be external or internal, traverse feed or plunge grinding. The most common type of center less grinding is the external traverse feed
The grinding wheel was introduced to improve the operation of a 40-hp Cincinnati Twin Grip centerless grinder, which is used for rounding and polishing Inconel barstock. Part OD was 0.5 inch to 1.75 inch and part length was 378 inches to 384 inches.
Center-Type Cyclindrical Grinding A type of grinding in which abrasive cutting is used to remove material from a workpiece. Centerless grinding differs from centered grinding operations in that the workpiece is secured between two rotary grinding wheels. Cyclindrical grinding in which each end of the workpiece is mounted on a pointed bar, or ...

grinding machines, bufting machines. and reciprocating surface grinding machines. UTILITY GRINDING MACHINES The utility grinding machine is intended for offhand grinding where the workpiece is supported in the hand and brought to bear against the rotating grinding abrasive wheel. The accuracy of this type of grinding machine depends on the
As the name implies, centerless grinding involves the grinding of cylindrical parts without locating the part on a specific center line between centers. The centerless process is commonly used for high volume production, and it's also easily used for low volume production because the machine setups are fairly simple.
The process of using a centerless grinder to machine such workpieces is also known as grinding the workpieces or removing stock from the workpiece to obtain the desired configuration. Centerless grinders are particularly useful where precision tolerances are required and where particularly accurate profiles are desirable.

Grinding GrindingProcesses…Centerless Processes…CenterlessGrinding Grinding Center less grinding is a process for continuously grinding cylindrical surfaces in which the work piece is supported not by centers or chucks but by a rest …
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.
Centerless grinding is an OD (outer diameter) grinding process. Unique from other cylindrical processes, where the workpiece is held in the grinding machine while grinding between centers, the workpiece is not mechanically constrained during centerless grinding.
Dual grinding machines deliver a two-step process that combines centerless grinding with grinding between centers, alleviating concentricity concerns. In the Zone. Regardless of machine design, the workpiece is guided by its outer surface during centerless grinding. Because of this, roundness can be a concern, especially lobing and triangulation.
