Side milling involves cutting through the material vertically to produce a flat surface. The cutters used for this process are side mills, wherein the cutting edge is situated around the circumferential area of the cylindrical cutter.
Read MoreThe properties of aluminium alloy powders change with variations in the atomisation process, however metal AM is more suited to powders with a spherical morphology. Spheroidal and occasionally nodular powders will also work, depending on the machine technology used, the powder flow properties and other characteristics of the powder.

Read MoreSimilar processes are used to make technical ceramics from more refined powders. A principal process sequence is compaction and sintering. This method can be applied to nearly any ceramic, but it is almost exclusively used for the processing of polycrystalline ceramics, and rarely to ceramic glasses, which have much more flexible melt-based ...

They are the mill of choice when you need to precisely control the particle size reduction process. It is important to get the feed throat angle matching the material characteristics - a vertical inlet for fragile material or horizontal for fine grinds.

Read MoreThese powders were wet vibratory milled and the empirical observation was that they were much more friable and took only a fraction of the time to mill than conventional alpha powders took. The process described herein produces an alumina powder which is more easily millable than conventional powders and which has an ultimate alpha crystal size ...
