Belt grinding is an abrasive machining process used on metals and other materials, this process enables a higher production efficiency, and imposes less strain on the work piece when compared to other forms. The belt grinder machines with coated wheel are commonly used for roughing and finishing cylindrical, flat and conical surfaces, while how do they achieve those effects? It can start from their classifications.
Belt Grinder Machines can be classified into Platen, Contact Wheel, Free belt and Centreless. Cutting and grinding wheels are driven directly by the motor. During this process, a coated abrasive belt travels over a wheel, which serves to apply on opposing pressure to the work piece.
Abrasive belt machines are usually classified by the surface that forms the backup of the coated abrasive at the work area. This backup plays a crucial role on the material removal rate and on the finish. The backup governs the angle of cut, choice of contact pressure and the speed of operation.
1.Finishing refers to leveling rough surfaces, removal of micro burrs, cosmetic finishes and polishing.
2.Deburring includes radiusing, burr removal and edge breaking.
3.Stock removal includes high stock removal, cleaning for example corrosion, eliminating mill or tool marks and dimensioning.
