Keep Your Cylindrical Workpieces Running ... - UNITED GRINDING

One of the biggest sources of roundness errors in cylindrical grinding involves the centers that hold your work in place. Like the small contact patches through which vehicle tires establish traction on a road, the centers that enable workpiece rotation make contact with the part through the small tips of a pair of cone-shaped metal points that match up with corresponding centers on the ...

Cylindrical grinder - Wikipedia

There are five different types of cylindrical grinding: outside diameter (OD) grinding, inside diameter (ID) grinding, plunge grinding, creep feed grinding, and centerless grinding. OD grinding is grinding occurring on external surface of an object between the centers. The centers are end units with a point that allow the object to be rotated. The grinding wheel is also being rotated in the same direction when it comes in contact with the object. This effectively means the two surfaces will be

Grinding (abrasive cutting) - Wikipedia

The five types of cylindrical grinding are: outside diameter (OD) grinding, inside diameter (ID) grinding, plunge grinding, creep feed grinding, and centerless grinding. [2] A cylindrical grinder has a grinding (abrasive) wheel, two centers that hold the workpiece, and a chuck, grinding dog, or other mechanism to drive the work.
