摘要： Organic bonded abrasive tools, having controlled microstructures, comprise a relatively low volume percentage of abrasive grain and a relatively low hardness grade, but are characterized by the excellent mechanical strength and efficient grinding performance of much harder grade, lower porosity tools, especially in versatile grinding processes, such as centerless grinding. A method for centerless grinding with these tools is provided. Methods for making the abrasive tools utilizing agglomerated abrasive grain are described.

摘要： Bonded abrasive tools, having novel porous structures that are permeable to fluid flow, comprise a relatively low volume percentage of abrasive grain and bond, and a relatively low hardness grade, but are characterized by excellent mechanical strength and grinding performance. Methods for making the abrasive tools utilizing agglomerated abrasive grain are described.

摘要： Grinding of mill rolls is carried out with chatter resistant abrasive grinding wheels having relatively low elastic modulus values and relatively hight burst speed values. Grinding operations may be carried out at high efficiency with controlled wheel vibration, thus generating optimum surface quality on the ground mill rolls.
