Processes of grinding wheelThe processes of grinding wheel. Vitrified process (V) The bond for the vitrified grinding wheel is made up of a mix of feldspar, pottery stone, clay, silica rock, talc and frit. The main ingredient, abrasive grain, is added to the bond and the grain which are then kneaded into a state of wetting and are pressnolded. After drying completely it is fired at approximately 1300C. ...
Frequent problems during grinding – grindaix So that a grinding process runs without the occurrence of grinding burn, ... The coolant lubricant transported in this way is introduced precisely into the machining zone and can cool the process reliably there. Grinding wheel loading. If a grinding wheel is highly loaded, the pore spaces become clogged. This means that the grinding wheel can then no longer transport any coolant lubricant and ...
TYPES OF GRINDING WHEELSTruing is the process of changing the shape of the grinding wheel as it becomes worn from an original shape, owing to the breaking away of the abrasive and bond. This is done to make the wheel true and concentric with the bore, or to change the face contour for form grinding. Truing and dressing are done with the same tools, but not for the same purpose. The only satisfactory method of truing ...
