The Dolce series is a new grinding wheel that combines a new bond that acts softly with pores of the optimal size and amount for high-hardness metal workpieces. In addition to high-hardness workpieces, it is also effective for thin material processing and low-rigidity workpieces. The grinding sound is light and soft, and there is little heat generated, making it possible to set a finer grain size than before, making it an evolved grinding wheel suitable for high-precision processing.
