qw material removal rate grinding

Winter has set a high standard in the machining of shank-tools with its Q-Flute2 for flute grinding operations. There is an improved material removal rate using the Q-Flute2. This is possible whilst at the same time maintaining edge stability and results in a successful combination of durability and free-grinding behaviour.

Material removal rate in grinding is usually quoted in terms of removal rate per unit width of grinding contact. Removal rate per unit width is known as specific removal rate Q′. Using the specific removal rate reduces the number of variables and allows direct comparison of removal efficiency across a wide range of operations (Fig. 2.7).

CALCULATING SFPM The performance of grinding wheels and quality of the finished workpiece is affected by how fast the abrasive grains sweep over the workpiece. That speed affects surface quality, workpiece burn, material removal rates, and other factors. Since the speed of the abrasives on the wheel perimeter depends upon the diameter of the wheel, RPM isn't a useful measure.
