ABRASIVE TOOLS FOR DEBURRING CERAMIC TILES

In the ceramic manufacturing process, tools known as "felt discs" are used to clean the outer edges. These are non-woven fabric wheels containing a very fine silicon carbide abrasive grain.

ABRASIVE WHEELS DIMENSIONS


The range of tools for this type of application consists of wheels with an external diameter of 150 mm and a 50 mm hole and, to a lesser extent, wheels with an external diameter of 200 mm and a 76/80 mm hole . The most commonly used thickness is 40 mm, followed by 50 mm and other smaller ones. The maximum speed is 3200 rpm for the 150 mm wheels and 2500 rpm for the 200 mm ones .

WHEEL DENSITY

The density of a wheel depends on the number of flaps it contains . Given the same density, the number of flaps can vary depending on the type of material. Given the same pressure, a soft wheel has flaps that flex more than a wheel with a higher density; therefore, the more flexed flap leaves a longer mark on the worked surface than the flap that works at the tip .
