Ceramic grinding is a design and manufacturing process whereby an abrasive is used for material removal, dimensioning and finishing of ceramic components and products. This process, used in many commercial and industrial settings, facilitates the creation of precise ceramic pieces. The products of ceramic grinding can be seen in industrial, commercial and domestic products.

Medical, aerospace, automotive, electrical, semiconductor, microwave and even defense industries utilize a wide variety of ceramic products that are made and finished by grinding. Products such as ceramic balls for water filtration, cooling flanges, pipeline connectors, armor, rods, tubes and insulators all necessitate the accurate manufacturing offered by ceramic grinding. Several grinding techniques utilize this abrasive process in different ways to create these precise ceramic objects. Centerless, creep feed, double disc, internal, external, jig, surface and thread grinding are among the most popular services available. As a finishing technique, ceramic grinding removes cuts, scratches, scuffs and other breaks in surface continuity to improve product quality. This fine finish is especially important for precision products such as those used in aerospace, medical and inspection contexts. Additionally, ceramics can be used as the abrasive agent to grind products made of ceramics or other materials such as brass. While all ceramics are known for extreme hardness, cubic boron nitride is most often used in this context as it is second only to diamonds in terms of hardness.
In general, grinding machines consist of an abrasive that is bonded to a wheel, belt or disc. As aforementioned, ceramics such as alumina, silicon carbide and cubic boron nitride often serve as the abrasive grain when grinding other materials. These materials hold up extremely well to elevated temperatures, chemicals, bacteria and wear making them suitable to the consistent friction encountered in most grinding situations. Despite the many benefits of using ceramic abrasives, synthetic diamond superabrasives are most often used when grinding ceramics as only their hardness surpasses the materials to be ground. Combustion engines, electric motors, or pneumatics are used to drive these devices. The wheel, belt or discs may be rotary, creating orbital or linear motions, or simply vibratory, oscillating back and forth across the materials to be shaped. Different ceramic grinding machines allow for even custom shapes to be designed. Often, manufacturers will utilize computer aided drafting to quickly and accurately determine the necessary material removal. This data can be uploaded to computerized machines or serve as a guide for less autonomous grinding machines. Other specifications to consider when selecting a grinding technique or machine include outer diameter, inner diameter, thickness, rotary speed and mounting capabilities.
