Benefits of Using Wire EDM for Gear Cutting
Using wire EDM (Electrical Discharge Machining) for the manufacturing and cutting of gears is a highly beneficial production process, particularly when dealing with specialized parts like helical gears, bevel gears, and other gear systems. The intricacies involved in gear cutting make minimizing machining steps desirable.
How Does Wire EDM Work?
In this machining process, the workpiece is immersed in a dielectric fluid, mechanically clamped using a wire EDM vise, and then a wire is threaded through the workpiece, generating sparks when an electric current passes through.
In other words, one side of the wire carries a charge, while the workpiece (which must be a conductive material) carries the opposite charge. When they come close, thermal charges jump the gap, melting tiny metal particles.
The electrical discharge is the cutting tool that shapes the material as needed. Additionally, the wire EDM process requires the use of deionized water to control the process and flush away the removed tiny particles.
Due to the precision of wire EDM, gears require less post-processing after the part is completed. This becomes especially crucial when considering zero-interference design and preventing meshing interference in gears. Wire EDM machining eliminates the need for special tools (aside from the wire itself) and specific fixtures, making it straightforward to achieve rough cuts for gears. The complexity of wire EDM machining also benefits from the machine's capability to cut internal features, splines, and other critical characteristics of gears. Furthermore, compared to traditional machining processes, the time for cutting hardened metals and steel is shorter, reducing lead times and accelerating the gear manufacturing process.
At this point, the use of wire EDM eliminates the need for outsourcing or, in some cases, entirely eliminates the need for broaching gears. Broaching typically involves the use of special tools (called hobs) to remove material from intricate parts. Gears are often components that may require broaching, depending on their application. However, with wire EDM machining, broaching is not required, saving both time and money in the manufacturing process.
Utilizing wire EDM machines for gear cutting also offers environmental benefits. Since there is no need for cutting oils commonly used in traditional machining, there's no handling of contaminated or used fluids, solvents, or metal chips. This reduces environmental impact and lowers the risk of injury for machinists. It also means eliminating any associated costs with handling oils and metal chips, making both manufacturers and the environment more content.

FAQ
Q: What materials can you cut?
We can cut any conductive materials, including: chromium-nickel iron alloys, titanium, aluminum, stainless steel, carbon steel, hard alloys, and so forth.
Q: How fast can you make my EDM products?
The EDM process is most suitable for machining conductive metals. Soft materials such as lead, gold, silver, tin, zinc, aluminum, thorium, copper, brass, and bronze have a fast cutting speed. Harder materials like tungsten carbide, titanium, chromium-nickel iron alloys, steel alloys, chromium, magnesium alloys, and iron have a slower cutting speed.
If your specific project requires tight tolerances or positional tolerances (below 0.001 inches), achieving such precision may involve multiple EDM cuts or burns, which, in turn, require more time.
The thickness of the part is also a determining factor in time. The thicker the part, the slower the speed. When the thickness exceeds 4-5 inches, the cutting speed of wire EDM decreases.
