Machining The Impossble – Wire EDM Services
Wire EDM is an electrothermal production process that uses electrical discharges to remove material from a workpiece. It is an improvement over traditional EDM methods and can create extremely complex designs and shapes. As a result, wire EDM is used by part manufacturers in many industries and is highly recommended in many CNC machine shops. At AN-Prototype, our EDM skills are the perfect solution to your needs for manufacturing high precision parts.
What Is Wire EDM Machining?
Wire-cut electrical discharge machining (WEDM) is an electrothermal process used to cut conductive metals. Conductive metals include alloys, superalloys, steel, aluminum, brass, bronze, copper, carbon graphite, carbon steel, stainless steel, Inconel, and titanium. The wire-cut electrical discharge machining (EDM) process uses thin single strands of wire that are passed through the workpiece with high-pressure deionized water. The tens of centimeters of electrode wire fixed on the spool is fed between two guide rollers, just like the blade on a band saw, and then driven along the path guided by the controller. During EDM metal cutting, an electric current is used to erode the conductive material of the workpiece, leaving an extremely smooth and uniform surface without the need for additional finishing or polishing processes. During this process, the cutting wire never touches the workpiece material. EDM cutting occurs when a spark is formed between the material and the cutting wire in a so-called voltage gap. Wire EDM is ideal for complex parts with extremely tight tolerances, such as tightly regulated medical or aerospace parts.
Advantages of Wire EDM
Why Choose Wire EDM Machining Service
AN-Prototype is an industry-leading rapid manufacturing company. With 15+ years of experience in this highly specialized field, we are one of the fastest, most accurate and efficient wire EDM manufacturers in the industry.
Create Unique Shapes
Because the wires on a wire EDM are so small and thin, it can cut unique, complex shapes with a precision that other cutting methods cannot achieve.
Machining Hard Material
CNC machining hard materials such as Inconel, titanium and nickel alloys is very difficult. Wire-cut EDMs cut through the toughest materials with ease.
Consistency
Even when the WIRE EDM machine is unmanned, wire EDM is capable of running multiple parts at once, resulting in a high degree of repeatability and consistency.
Tight Tolerances
AN-Prototype can control the tolerance within ± 0.002mm, and can cut extremely small corner radii that cannot be achieved by end mills.
Common Wire EDM Machining Materials
Wire EDM can create complex shapes and patterns on workpieces. In addition, they can process most conductive materials, even hard and brittle ones. Common shapes and materials that you can machine cut include:
Titanium
Wire EDM can withstand the stickiness of this titanium alloy and break down long chips. Of course, this requires deionized water as the dielectric to control the heat generated during processing.
Aluminum
Aluminum has excellent thermal and electrical conductivity. However, aluminum is inherently soft and thus can be challenging during wire EDM processing as it can lead to sticky buildup after machining.
Steel
Steel is a very strong conductive metal. Wire cut steel parts are an effective alternative to CNC machining. However, wire-cut steel parts generate a lot of heat, so necessary precautions need to be taken.
Brass
Brass is easy to cut with machines because of its high tensile strength. But since it is a soft metal, the cutting speed should be slow.
Stainless steel
Stainless steel parts with complex structures are very difficult for CNC milling, such as square corners close to 90 degrees, and wire cutting can achieve such designs.
Graphite
Graphite can be difficult to cut using conventional CNC cutting tools. Wire-cut machining of graphite is suitable because the wire is sharp, preventing particle pull-out.
wire Material
Wires are used as electrodes to generate the discharge. The diameter of the wire directly affects the shape and thickness of the workpiece. Typically, wires with diameters ranging from 0.05 to 0.25 mm can be used. The main types of wires used include
Brass Wire
Brass is the most common EDM wire material due to its excellent electrical conductivity. It is an alloy of copper and zinc, the higher the zinc content, the faster the wire cutting speed. However, there should be a balance, because when the zinc content exceeds 40%, it will reduce the corrosion rate of the brass wire.
Galvanized wire
As the name suggests, it is obtained by coating the surface of the wire with a coating of pure zinc or zinc oxide. Manufacturers use galvanizing lines because it allows for faster processing.
Diffusion annealed wire
The diffusion annealing process facilitates the production of wire with a higher zinc content (more than 40% zinc). These wires are ideal for mass production and can process a wide variety of materials.
