Abrasive belt grinder plays an important role in machining field. It can meet a variety of processing requirements. The concept of abrasive belt grinding was introduced briefly.The working principle and main structure of a new belt grinder for removing rust on steel wire surface were illustrated.Then the relationships among the grinding force,the metal removal rate,belt wear rate,grinding ratio,grinding depth and wire walking speed were studied through experiment. The research work provides rational parameters for wire snagging line with abrasive belt.
