Wire Electrical Release Machining, Wire EDM, is a machining method that uses a wire fiber that helps an electrical charge through the wire and is utilized to flat head screws cut off the hard metal components. There are several major parts needed for the wire EDM machine, not the slightest of which is the wire utilized to evacuate the metal so as to shape the feature being produced. The level of exactness and the sums of materials that might be evacuated through successive passes are stupendously dead set by the organization of the wire, normally copper wire, and the sort and solidness of the electrical current. Positively, the more fabulous the distances across of the wire, the more material that might be cut with every pass; then again, the exchange-off [...]

It is more than 2 times of the speed of free forging hammer. In the study of high velocity compaction of iron powder,Phillips Screws Factory copper powder (FCu), soft magnetic materials in different processes and different companies, scientists get the expected regular patterns of density changes. With the increase of suppression and suppress pressure, the density is improved. The study found that the density increases rapidly with the suppression rate increase. When the density is more than 7.9m • s-1, the sl growing speed becomes slower.Compacting pressure by the static pressure into dynamic pressure, high velocity compaction powder body by the static pressure P and the role of the momentum mv, short duration of action, instantaneous impact force F = mv / t great, so that the density of [...]
