For these long, productive passes, MÄGERLE and BLOHM machines come equipped with continuous dressing systems to maintain wheel sharpness throughout the entire operation.
Grinding Wheel: Cutting Wheel: The grinding wheel has good strength which avoids cutting improper shape and size. The normal cutting tool doesn't have abrasive. So it will not provide better finishing accuracy as grinding wheel provides. The chances of wear and tear are high in cutting wheel : A grinding wheel having low chances of wear and tear.
