Coated abrasive machining of 1018 steel, 1095 steel and 304 stainless steel at moderate to high rates of stock removal using a buffered tri-potassium phosphate solution

A coated abrasive machining method that results in moderate to high metal removal rates was used in evaluating a 10% aqueous solution of K 3PO 4 as a grinding aid. The K 3PO 4 solution was buffered with NaH 2PO 4 to reduce its caustic nature and to add additional phosphate ions to increase the grind...

Description
Summary:A coated abrasive machining method that results in moderate to high metal removal rates was used in evaluating a 10% aqueous solution of K 3PO 4 as a grinding aid. The K 3PO 4 solution was buffered with NaH 2PO 4 to reduce its caustic nature and to add additional phosphate ions to increase the grinding aid effect. Tests run on 1018 steel, 1095 steel and 304 stainless steel at three rates of metal removal show that the phosphate solution increases the amount of metal that can be removed with an abrasive belt over that removed in dry grinding or with some commonly used watersoluble commercial lubricants. By reducing the rate of mineral wear on the belt, the K 3PO 4 solution both increases belt efficiency and reduces thermal surface damage to the workpiece.
