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.

For grinding round bar stock, a "through grinding" process is used. A bar of material, typically twelve feet long, feeds into the grinding machine between a grinding wheel and a regulating wheel. A carbide-tipped strip of steel, the work blade, supports the bar and holds it at the correct height, above the centerline of the grinding and ...

Centerless grinding is the process of removing material from the outer diameter of a workpiece using a grinding wheel. The workpiece is located on its outer diameter and supported by a working blade located between the adjusting wheel and the grinding wheel. The adjustment wheel drives the machined parts, and the grinding wheel removes material.

Here are some representative process data to illustrate a NCD creep-feed grinding calculation: Max. diameter of wheel: 16 inch. Min. diameter of wheel: 10.5 inch. Usable abrasive (radial): (16 – 10.5) / 2 = 2.75 inches. Dress amount per part (radial): 0.006 inch. Wheel life is then 2.75 / 0.006 = 458 parts per wheel.

(2) High durability, low wear, and the grinding ratio can reach 4000:10000. Grinding ratio refers to the ratio of the amount of workpiece material removed during the grinding process to the amount of grinding wheel wear. The ordinary corundum grinding wheel is only 50-80°C. The use of CBN for ring grinding is a new processing technology.
