Grinding gummy materials can load up a grinding wheel, which will result in heat generation, burn, poor surface quality, and the need for additional dressing. In this scenario, generally a softer grade, porous grinding wheel is needed with a friable abrasive that'll fracture a bit easier and produce new, sharp cutting points to continue ...
Grinding wheels made with vitrified bonds are very rigid, strong and porous. They remove stock material at high rates and grind to precise requirements. They are not affected by water, acid, oils or variations in temperature. Vitrified bonds are very hard, but at the same time they are brittle like glass.

This combines the advantages of a porous ceramic structure with the wear resistance of a metal bonded matrix. The result is a structure which offers both a unique range of dressing tools for the dressing of vitrified abrasive wheels as well as a new generation of grinding tools for machining brittle-hard materials.
Innovative aggregate grinding wheels were used for grinding. The aggregates containing diamond abrasive grains, connected with a metal bond, were embedded in the porous structure of the resin bond. The aggregates ensured high efficiency of grinding, and their developed surface contributed to good holding in the resin binder.
It is significant to design porous catalysts with increased active surface and reveal more catalytic sites for improving catalytic performance.

As my previous article of Grinding Machine, I told, grinding is an important operation in manufacturing industry to get a final product, so for that, we need to know about the grinding wheel and its properties so that we easily choose a right wheel for the right material.. I assumed that you already have a brief idea about Grinding Machine. Don't worry! if you not learned yet …
Creep feed grinding achieves significantly higher productivity in mass production compared to reciprocating grinding. With today's conventional, highly porous grinding wheels, very high material removal rates are achieved with creep feed grinding. The wheel wear is typically lower than in reciprocating grinding.
Organic porous fluorescent materials created by supramolecular noncovalent synthesis can be developed for fluorescent sensing applications. In this study, we report a noncovalent synthesis of a near-infrared porous fluorescent crystal and its solvent vapor-responsive fluorescence change.
