For the right application, electrical discharge machining (EDM) can transform how your intricate parts and components can be designed and crafted.
At The Technology House (TTH), our team can use this process to create your precision parts, moving them from design to delivery in a matter of weeks, while prioritizing both cost-effectiveness and uncompromised quality. EDM can set a new benchmark for precision component manufacturing and give you a significant advantage in your industry.
At its core, electrical discharge machining is a non-traditional, subtractive manufacturing process that employs electrical discharges to shape materials. The process involves two primary components: an electrode and the workpiece. These are submerged in a dielectric fluid, and an electrical current is applied. This results in a controlled and repetitive series of electrical discharges, removing material from the workpiece in a meticulously exact manner. Here at TTH, we use electrical discharge machining when conventional methods are unable to create your specific geometric features, or the type of material isn't conducive to traditional machining, due to hardness or composition.
The EDM process offers many benefits, including:
Electrical discharge machining is renowned for its extreme level of precision, capable of achieving tolerances as tight as one micron, or 0.001 mm. This is primarily achieved by controlling the electrical discharges that assist in the removal of material from the workpiece, and is used in the following two types of EDM:
With traditional methods such as CNC machining services, you are limited on the level of accuracy and types of materials that can be processed. With our Wire and Sinker EDM processes, workpiece material is virtually unlimited, allowing you to envision new possibilities for your projects. At TTH, we work with several feedstock materials, including:
Other options, including exotics and precious metals, and nearly anything conductive can also be shaped with incredible precision, depending on your specific needs.
We know how hard it can be to balance innovation with efficiency. Electrical discharge machining can offer you significant cost advantages, especially for intricate and hard-to-machine components. Because there's no degradable tooling involved, the often-challenging adjustment for wear is eliminated, saving both time and money in crafting unique parts and components.
As an example, we were recently tasked with creating a 0.006” wide slot in stainless steel for a highly specialized manufacturer. We were able to use a 0.004” brass wire to cut the slot in a single pass. By stacking the workpiece materials into an in-house custom fixture, our team was able to cut multiple pieces at a time, increasing the efficiency of the entire process.
Our EDM technology significantly boosts the production process, allowing us to deliver quicker transitions from design to market. Because EDM requires fewer setup requirements compared to conventional machining, the manufacturing process can be sped up, so you can get your products to market more quickly.
Known for its incredibly smooth surface finish, EDM not only improves the aesthetics of your components but also their functionality. This feature reduces the need for post-processing on our end, while offering you extended durability through reduced friction, potentially increasing the lifespan of your components.
EDM’s precision and reliability are crucial in industries involving high-value parts and components. Examples include:
We are ISO 9100 certified for aerospace and NADCAP approved, as well as ISO 9001 certified for quality management and ISO 13485 certified for medical devices.
