What’s Abrasive processing?
Abrasive processing is a process in which a large number of small abrasive particles are used to remove material from a workpiece. Common examples include grinding, honing and polishing. Abrasive processing is usually more expensive, but its grinding tolerances are smaller and the surface finish is better than other machining processes. Usually based on how the grains are applied to the workpiece,there are two abrasive processing, including Fixed (bonded) abrasive processes and Loose abrasive processes.
How abrasive machining works?
Abrasive processing works by forcing abrasive grains or grains into the surface of the workpiece so that each particle cuts off a small portion of the material. Grinding is similar to traditional machining, such as milling or turning, because each abrasive grain acts as a micro-cutting tool. Grinding power is less efficient and generates more heat. The grain size based on processing may vary. For coarse grinding, use coarse abrasives. For fine grinding, fine particles (abrasives) are used.
In the bonded abrasive process, the particles stay together in the matrix, and their combined shape determines the geometry of the finished workpiece. In the loose grinding process, there is no structure that connects the particles. They can be applied as dry powders without lubricants, or they can be mixed with lubricants to form a slurry. Since the grain can move independently, it must be forced into the workpiece with another object (such as a polishing cloth or a lapping plate).
