  • Powder metallurgy – basics appliions

    In dry milling about 25 vol% of powder is added along with about 1 wt% of a lubricant such as stearic or oleic acid. For wet milling 30-40 vol% of powder with 1 wt% of dispersing agent such as water alcohol or hexane is employed. • Optimum diameter of the mill for grinding powders is about 250 mm Ball Mill

    A smaller ball interpolated exposes more of the surface to a faster moving cutter leading to a better finish. But the smaller cutter can flex more. Hence the need to balance these two factors. If you have a 4th axis or 5-axis mill you can try “Sturz” milling to combat the slow moving tip. See below for details.
