Grinding Ratio Ignored by Most People is Very Important!

Grinding ratio refers to the cutting efficiency of grinding wheels. The less wastage (be refurbished content) grinding wheels lose, the more the workpieces are cut, and the higher the grinding ratio will be. It also represents the better the performance of grinding wheel. The calculation is: grinding wheel wear volume/artifact removal volume.

As for the high and low standard data of grinding ratio will be different for various types of bond (ceramics, resin, rubber, etc.), and its loss speed is also different. It still needs other abrasive grades, thickness of each particle size, all kinds of hard and soft binder and other parameters for the correct grinding ratio.

The basic concepts of grinding ratio: The materials removing amount of workpieces and the wearing capacity of grinding wheel is called grinding ratio.

Grinding ratio energy - Es refers to the energy that is consumed in the workpiece material removal of unit volume per unit time. It usually can be expressed as: Es = Pmvwapb, and Pm means energy consumption

The grinding ratio G = Vwc/Vsc; Type: Vwc - The workpiece volume that is removed; Vsc - The wastage volume of grinding wheel.

Grinding ratio is an important common indicator in grinding wheel using economy. The larger the grinding ratio, the more wear the more removing metals. Because grinding wheel consists of abrasive binder, porosity and other part volume, the wear volume of grinding wheel - Vsc also includes these three parts. Sometimes, the abrasion ratio Φ also can be used to represent the economy when using grinding wheels.
