CNC Wire Cut EDM Machine
Instead of cutting material, EDM melts or vaporizes it, producing relatively small chips and providing a very precise cut line. Use an EDM to cut conductive materials from aluminum and copper to graphite. EDM technology allows you to achieve extreme precision while producing extremely precise parts at very high cutting speeds. It's also not limited to death and mold. Since only one tool is required, it is also a low-cost alternative to milling, turning, grinding, turning or broaching. What's more, you can use the multipurpose EDM to complete a range of different processes, even unattended.
The main advantage of a wire EDM machine over a conventional EDM machine is that the continuous wire feed minimizes the wear that occurs with a stationary electrode. However, a wire EDM machine can use a lot of wire, which increases costs. Many wire EDM machines are self-threaded, so if the wire breaks, the process can continue almost continuously.
Another important advantage is the ability to cut parts after heat treatment, which eliminates the possibility of deformation resulting from post-treatment. In addition, since wire EDM does not apply pressure to the tool on the workpiece, small, delicate parts are easily machined. Fixing requirements are minimal compared to conventional machining methods. Very fine surfaces are possible.
Wire EDM Applications
Due to their versatility, manufacturers use EDM machines for a wide range of applications. Because the process can cut very small parts, it is often ideal for producing small, very fine parts that are often too fine for other machining options. Additionally, the process is cost-effective for low-volume designs and can prove beneficial for prototyping even if the actual design is done differently.
Note that the wire in the process is constantly moving and cannot be reused. As a result, copper, brass, or other metal wires can be miles long, adding to the cost of the process. While the process uses no force, so there is no burr and can be used on delicate items, there is definitely the potential for thermal stress.
Most WEDM operations start with a rough cut with fairly high feed rates and high dielectric currents. The subsequent debinding process requires smaller cuts and reduced dielectric current to achieve tolerances on the finished surface. The reduced dielectric current prevents deformation of the wire during these transitions.
Cuts that do not start along the edge of the part, such as holes, need to be pre-drilled to allow wires to pass through. Many wire EDM machines have small hole drilling electrodes for this purpose, which allow starting holes to be made in hardened steel without the use of conventional drills. Small hole drills typically use an EDM electrode mounted in a rotating mandrel through which a dielectric is pumped to flush the hole. The process of making small holes in hardened materials using a standalone EDM bit is sometimes called hole popping.
6 Frequently Asked Questions about CNC Wire Cut EDM Machine
Wondering what else the Wire Cut EDM Machine can do?
1. What is the maximum material thickness you can cut? While entry-level EDM machines can typically only cut material about 8 inches thick, Arbiser Machine's high-tech equipment can cut material up to nearly 15.75 inches.
2. What materials can you cut? We can cut anything that conducts electricity, including: Inconel, Titanium, Aluminum, Stainless Steel, Carbon Steel, Carbides, and more.
3. How accurate is wire cutting? Our state-of-the-art Wire Cut EDM Machines have +/- 2 microns (0.00008”) positioning and contouring accuracy, which means they are more accurate than we can effectively measure.
4. What kind of surface finish can be achieved with Wire EDM? We make three types of cuts: rough, fine and surface finish. With polishing passes, we can reduce Ra to 0.08µm for many materials without additional finishing operations. The end result is a very smooth finish on a microscopic level. (With extra manipulation, we can achieve a 2 µin specular finish.)
5. How big of a part can you cut? We can use the x, y, z travel to cut the part, about 23.62 inches in the X axis, 13.77 inches in the Y axis, and 15.75 inches in the Z axis.
6. How many parts can you make at one time? Depending on their size, we can manufacture multiple parts simultaneously using our extensive 3R tooling that accurately loads multiple jobs into the machine at once. We can also stack the pieces together and drop a wire down the same path, pulling 16, 20 or even 40 pieces at the same time in a single cut.
7. How does Wire EDM compare to CNC machining in price? It is a misconception that Wire EDM is expensive. The truth is that when used properly, spark machining can achieve the most complex functions at an affordable price.
