A balancing act between speed and surface finish is inherent to wire EDM cutting. This technique requires quick, repeated, regulated electrical discharges along a strand of metal wire. This machining method offers a broad processing spectrum for conductive materials, including hard ones like tungsten and molybdenum. It can create incredibly precise cuts and adhere to rigorous tolerances, eliminating the need for item post-machining and polishing.
Brass Wire
Brass is a metal that offers a unique combination of malleability, strength and corrosion resistance. It is easy to cut, shape and hammer into different shapes and can be soldered with ease. It also has high electrical conductivity, making it an ideal material for use in wiring. Plain brass wire possesses a tensile strength between 54,000 and 173,000psi, depending on the alloy composition. These wires are typically a shiny brass color and come in hard, soft and half-hard tempers. Soft brass is used for cutting tapers, as it has a low tensile strength that allows it to bend while cutting at an angle without breaking. Hard brass has a higher tensile strength and is best for roughing or skimming because it withstands aggressive flushing better than soft brass. Unlike other cutting techniques, wire edm clamps cuts without impact.
Zinc-coated brass EDM wires contain a layer of pure zinc that protects the core from heat by reflecting it back onto the workpiece. This prevents the brass from melting and burning and increases machining speed by up to 15 percent. The coating is applied by electro-galvanization or hot-dipping, and it may be coated in multiple layers.
Zinc-Coated Wire
Zinc-coated wire is made by plating a pure zinc layer on the surface of a copper or brass core. This coating protects the copper or brass from corrosion, allowing increased electrical currents to be used without increasing wire breaks. This type of EDM wire is particularly useful for cutting harder metals, such as tungsten carbide, which were traditionally difficult to cut using conventional EDM techniques. It also has good tensile strength, making it ideal for high-speed cutting.
The tensile strength of EDM wire is important because it can withstand the stress and strain of the cutting process. A higher tensile strength means the wire can be stretched more without breaking, which reduces the risk of the wire becoming stuck in the machine or damaging the work-piece surface. This makes it suitable for cutting tall parts and allows higher speeds to be achieved during machining. Unlike plain copper, coated wires can be reused for a longer time as they are much more durable.
Stainless Steel Wire
When choosing the right metal wire for your industrial projects, there are many factors to consider. In addition to the type of environment, pulling forces, and the strength of the material you need, there are also other considerations like appearance and price. Stainless steel wire cables are employed wherever a high degree of corrosion resistance is required in conjunction with good strength. This includes chemical, medical, and ship and boatbuilding industries.
They are also used for general electrical applications and mechanical uses, such as telecommunications, and in architecture and facade construction. They are also widely used in the construction of elevators, railway systems, and underground cable engineering. Stainless wire is also often found in modern medical devices, such as intra-arterial stents and angioplasty catheters, as well as in orthopaedic applications, including cerclage wire and bone nails. A good supplier will have a wide selection of stainless steel wire sizes and shapes to choose from. They will also be able to provide you with the best advice regarding which types of wires are best for your specific project needs.
Copper Wire
The copper wire edm clamps machines are usually sized according to the American Wire Gauge (AWG) system. The tensile strength of the wire is crucial to the performance of your machine. It must be able to resist what engineers call creep, the gradual deformation of metal unfair stress that may cause damage. This characteristic allows the process to cut hard and thin materials with high accuracy, eliminating the need for post-machining and polishing.
During the cutting process, an electric current is pulsed between the electrode and workpiece. This creates ions and electrons, which cause the material farthest from the electrode to be melted or vaporized. This melted material is then flushed away by the dielectric fluid. The machinist can choose to cut in a specific direction, or let the machine automatically make the necessary paths to reach the desired results. It can also cut curved paths, which are impossible with other processing methods.
