ABSTRACT:
A metal abrasive belt is used to grind, debur, sand, cut, finish or otherwise abrade a workpiece. The metal abrasive belt includes a continuous metal belt and abrasive particles electroplated onto at least a portion of an outer surface of the continuous metal belt. The abrasive particles are electroplated by electrochemically depositing an electroplating matrix, such as a Nickel matrix, in the presence of abrasive particles, such as diamond or Cubic Boron Nitride particles. The abrasive particles can be electroplated to form selected abrasive and non-abrasive regions on the continuous metal member, for example, by masking selected regions of the continuous metal belt. One embodiment of the metal abrasive belt includes one or more perforations extending through the continuous metal belt. The perforations facilitate cooling and allow swarf to pass through the continuous metal belt while abrading a workpiece. The continuous metal belt can also include one or more burrs at an intersection of the perforations and the inner surface of the continuous metal belt that facilitate gripping of the rollers or pulleys about which the belt is driven.
