The wire EDM machines used are one of the most precise manufacturing processes available to create simple or complex shapes and geometries in parts and assemblies. They are mainly used for hard metals or other materials that are considered difficult to mechanise with traditional methods. The materials are normally electrically driven, such as Hastelloy, titanium, iconel and covar.
Machine applications
Wire EDM machines have been developed for various industries, including the aerospace and medical industries. An EDM machine has different applications in metal fabrication. One of the most common is molding. By clearing metals, operators can generate metal parts for aerospace, automotive or electronic equipment. In addition, operators use the machine to produce jewelry, coins and other artwork. In addition to shaping, they can drill narrow holes in the metal, which is useful for creating airflow or for passing wires. It is also possible to remove broken tools from other parts for a particular purpose.
Benefits of use
Efficient production capabilities: Since the speed and accuracy of wire EDM machines have been introduced to the market, manufacturers have found that many parts can be produced economically than conventional machining.
Reduced costs: Used machines have significantly reduced the costs of most parts manufactured. Conventional machining often leaves sharp bars and edges, but the radio is made with wire machines at no additional cost.
Reliable Repeatability: Constant machine reliability is one of the best advantages. Since the programs are computer generated and the electrode is always supplied from a coil, the last part and the first part are similar. In addition, the tolerances of tighter machining can be maintained at no additional cost.
Unlimited possibilities: With these machines many parts are economically produced, such as: precision screws and gauges, shaft and clamp grooves, keychains, split tubes, gears, hexagons, internal stripes, cams, extrusion molds and other exotic shapes.
Exotic materials: Hard or soft, they are capable of cutting any conductive material electrically.
When buying used machinery, it is good to know the extent of your renovation and the repairs you need. These include asking the seller outside of their return policy. When signing the agreement, a written agreement must be specified that includes the shipping procedures, payment method and obligations of both parties. You can successfully buy second hand wire EDM machines if you are dealing with the right seller.
