Abrasives Blog

Ceramic abrasives are natural, but we put them through a number of different processed to refine, harden and purify. Simply put, through mixing natural ceramics with some abrasive powders. These powders include silicon carbide and quartz. Ceramics are very uniform in structure with a microcrystalline finish. A microcrystalline material is a crystallized substance or rock that contains small crystals visible only through microscopic examination.

TOUGH. Ceramics will not dull as quickly due to its extreme toughness. That level of toughness will allow ceramic abrasives to provide outstanding grinding and finishing performance on a variety of different hard metals. 

FRACTURED. With the unique microcrystalline structure in the new Cibo ceramics everything is different.  The engineered ceramic abrasive crystals will now fracture under a range of pressure conditions. Often called friable, tiny pieces of grit will fracture off exposing fresh sharp material. 

CONSISTENT. Ceramic abrasives are a great choice on a wide range of materials including Titanium, Stainless Steel, Steel and even Aluminium. One material for all applications. 

cera-cut ceramic abrasives are easily recognisable by their signature colour. 

Historically zirconia is widely used in stainless steel applications as it has been found suitable for high pressure and grinding work. Aluminium oxide grain is commonly used on softer surfaces. Both have been on the market a long time, however with innovations and testing ceramic is by far superior. 

We have already mentioned the microcrystalline structure of ceramic abrasives. This allows your abrasive to stay sharper longer. 

Ceramics are extremely resistant, giving them a long lifespan. 

Unlike other materials, ceramic is not brittle. 

Ceramic abrasives work fast while also remaining a safe process for operators.  an answer to this item.

Coated abrasives, also known as flexible abrasives, are products that consist of a thin layer of abrasive grain attached to a substrate such as paper, cloth, etc The substrate can have varying degrees of flexibility ranging from extremely flexible (E weight cotton backings) to extremely sturdy (Z weight polyester backings). These substrates are used as backings for different types of abrasives: rolls, belts, discs and sheet goods. Coated abrasives are manufactured using abrasive grains; the most common are aluminum oxide, zirconium, ceramic and silicon carbide. The crude grains are crushed and separated into 

sizes, called grit sizes, using calibrated screens. 

Grits range from 12 (very coarse) to 1200 (very fine). Once the grains are separated  into sizes, they are attached to a  backing material using various bond techniques. Compared 

with other grinding tools, coated abrasives have many advantages such as high dimensional grinding accuracy, low grinding surface roughness, high grinding efficiency and wide processing range. 

Open coat: The abrasive grains  over approximately 50% to 70% of the coated surface of the backing. They offer greater flexibility, but are harsher cutting. Wood, soft metals and 

fiberglass sanding are typical applications for open-coat products. 

Semi-open Coat: it usually refers to about 30% reduction in the amount of grains on the backing and generally cuts less aggressive and will finish coarser per grit than closed coat products. 

Closed Coat: The abrasive grains completely cover the coated surface of the backing. The greater number of abrading points per square inch causes faster stock removal during the use and produces a better finish than open-coat.
