Abstract
A soluble abrasive is used to lap workpieces to overcome the problem of embedding and retaining abrasive particles in the workpieces. The soluble abrasives are dissolved from the workpiece even if they become embedded in the workpiece. For example, the abrasives may be dissolved with water and comprise ionic salts. The soluble abrasive has a hardness that is equal to or slightly greater than the hardness of the metal being lapped.
