In dry lapping, a mixture of 15g of abrasive powder, 8g of mixed fat, 200ml of aviation gasoline, and 35g of kerosene are used after soaking for one week. The grinding paste contains 20% to 50% abrasive powder, 25% to 30% oleic acid, 18% to 30% mixed grease, and in some cases, about 15% Vaseline is added for very fine powder.

Milling. Milling involves the mechanical breaking down of metal into a powder form. The starting material is usually in the form of coarse particles or scraps which are milled using ball mills, hammer mills, or jet mills. In ball milling, the particles are broken down by grinding balls tumbling inside the mill.
