Binding agent plays the role of holding the abrasive and concrete cutting blades grinding a given geometry. It is an important sign of abrasive performance. Binders made from thermoplastic resin binder composition with a variety of fillers, (the widely used phenolic resin, polyimide resin, a small amount of application; apply some filler metal oxides), the nature of its various components usage how many have a great influence on the physical properties, mechanical properties and grinding performance binders, therefore, must be selected for the workpiece material properties, flat cutting disc in order to achieve good results.
