They assumed that three areas generate heat during grinding: the shear plane between the workpiece and the chip, the abrasive grain/workpiece contact, and …

Low-speed burr grinders are preferable because they minimize heat generation during the grinding process. By operating at slower speeds (around 300-500 RPM), these grinders limit the beans' contact time with the hot burrs, thus preserving their freshness. A heavier overall weight and larger grinding burrs can also help maintain low …

During the process of grinding a lot of heat is generated between the cutting tool and workpiece. A major portion of the heat is dissipated in the workpiece and the remaining is retained by the grinding wheel. ...
