Forms of Centerless Grinding. Thru-feed, In thru-feed centerless OD grinding the workpiece passes between two wheels, a grinding wheel and a regulating wheel. 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.
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.
28.3 Grinding Wheel Structure and Grade Grinding is where the abrasive is bonded into a wheel, and is the most common abrasive method. The grade of a wheel is a function of the rate of fracture of the abrasive from the surface. A wheel is graded as hard if the dislodging force is high and soft if the abrasive dislodging force is small

Sep 01, 2011 Centerless grinding involves a specific configuration of grinding wheels and workpieces. Traditional centerless grinders feature two parallel spindles placed side by side, one spinning a grinding wheel and the other a regulating wheel. The cylindrical workpiece is located between the wheels, supported by a stationary work blade.
Jul 03, 2021 Grinding Wheels. Grinding wheels have two major components the abrasive grains and the bond. The relative percentages of grain and bond, and their spacing on the wheel, determine the wheels structure. Different types of grains work better on different projects, as do different types and grades i.e. strengths of bond.
Sep 20, 2019 To meet the requirements of different workpiece material grinding, the grinding wheel is divided into different hardness grades. If the grinding wheel is hard, the abrasive grains are not easy to fall off, and the grinding wheel blocks easily and the grinding heat is increased, and easily burns the workpiece, and the grinding efficiency is low ...

During centerless grinding, the materials to be cut turn with the regulating wheel at the same speed. On the other hand, the grinding wheel turns faster on its axis and removes any foreign chips of materials as it passes by. When it concerns centerless grinding, there are two common techniques through-feed and in-feed grinding.
