    Apparent and tap densities of the powder mixture were achieved at 2.4 g/cm 3 and 2.96 g/cm 3 after dry milling and at 2.54 g/cm 3 and 3.39 g/cm 3 after wet milling, respectively. Wet ball milling causes fine particles to de-agglomerate and improves the critical solid loading, which is advantageous for submicron cemented tungsten carbide ...

    achieved by mechanically alloying Ti(C,N), W and Al in the high energy ball milling stage. Low level of Co in the infiltration layer was also achieved when sintering PcBN with this type of binder. A link was established between the addition of Al at the attrition milling stage and high oxygen content in the sintered PcBN, thus should be avoided.

    Consolidation has been done by Spark Plasma Sintering in order to maintain a fine structure of the material. In the Planetary Ball Mill, 25 g of HSS-powder was milled for 720 ks (200h) and resulted in a particle size of < 15 μm at an average grain size of 10 nm. Similar results in the Simoloyer were achieved after 72 ks under higher powder load.

    Ball nosed cutters: slow nose speed. The biggest challenge with ball nosed end mills of various kinds is slow nose speed. As you get closer to the tip, the diameter on the ball gets smaller and smaller, finally going to zero. As a result, the cutter must perform over a wide range of surface speeds and chip loads at different depths in the cut.
