What is
Precision CNC Machining
At Termite Precision, we own the power of Wire Electrical Discharge Machining (EDM) to deliver precision-engineered parts to our clients. Wire EDM is a specialized machining process that utilizes electrical sparks to form intricate shapes and details in metals. This is done by creating a controlled electrical discharge between two electrodes, immersed in a dielectric fluid, which precisely cuts through the metal by melting and vaporizing it.
The true strength of wire EDM lies in its ability to machine complex contours and minute details in materials that are typically challenging to handle with traditional CNC machining. This includes heat-treated steels, superalloys, and other special metals. With wire EDM, we can achieve parts with incredibly tight tolerances and fine details such as narrow slots and small holes with unparalleled accuracy.
Our wire EDM services are a perfect match for applications requiring exacting precision. Whether it’s creating components for aerospace, automotive, or intricate molds and dies, our technology ensures that every cut is precise and of the highest quality. Termite Precision’s commitment to precision and quality is backed by our advanced wire EDM equipment and our team of skilled technicians who are experts in their field. This combination makes us a leader in wire EDM machining, capable of delivering parts that meet the rigorous demands of any industry.
How Wire EDM
Machining Works
In wire EDM machining (Wire electrical discharge), a thin wire, precisely controlled and guided by computer systems, moves through a workpiece submerged in deionized water. The wire, acting both as a guide and electrode, uses electrical discharges to cut conductive materials accurately, resulting in parts with finely finished surfaces that seldom require further processing. Termite Precision state-of-the-art facilities ensure that even the most complex designs are executed with precision, reflecting our commitment to quality and client satisfaction.

Next, a thin metal wire is fed through the machine’s guides and the wire and workpiece are submerged in a dielectric fluid, usually deionized water. An electrical potential is applied, causing the fluid to break down and allowing an electrical discharge (spark) to occur, eroding the workpiece’s surface.
The final step is to precisely control the wire’s movement using a computer numerical control (CNC) system. The CNC guides the wire along a specific path, enabling it to cut complex shapes and profiles in the workpiece. The dielectric fluid is continuously circulated to remove debris and maintain temperature during the cutting process. Once the cutting is complete, the workpiece is removed, resulting in a high-quality, precisely machined part.

Advantages of Wire EDM Machining
Wire EDM offers several compelling advantages for precision machining:
- Precision and Accuracy: It is renowned for its ability to produce parts with extremely tight tolerances, often within +/- 0.0001 inches. This level of precision is crucial for industries such as aerospace, medical, and tool and die making.
- Complex Geometries: The method can create intricate and complex shapes that are difficult or impossible to achieve with traditional machining processes. This includes sharp inside corners, intricate patterns, and detailed contours.
- Material Versatility: It can cut through any electrically conductive material, including hard metals like titanium and hardened tool steel, without inducing stress or distortion to the material.
- Smooth Surface Finishes: The process often requires little to no post-machining finishing because it can achieve surface finishes as smooth as a 16 microinch Ra. This reduces the overall production time and cost.
- No Contact Cutting: Since the wire never physically touches the part, there is no cutting force involved, eliminating mechanical stresses during processing. This feature is especially beneficial for fragile parts or those with thin walls.
FAQs

Material Restrictions: It can only cut electrically conductive materials. This limitation excludes non-metallic materials such as plastics, ceramics, and composites, which cannot be machined using this process.
Cutting Speed: The cutting speed is generally slower compared to some traditional machining methods, particularly when dealing with very thick materials. This can result in longer production times for certain applications.
Operating Costs: The process requires a continuous supply of wire and dielectric fluid, which can contribute to higher operational costs. Additionally, the cost of the wire itself can be significant, especially for long or intricate jobs.
Complex Setup: Setting up and programming Wire EDM machines can be complex and time-consuming. Skilled operators are required to optimize the process and ensure precision, which can add to labor costs.
Surface Finish: While Wire EDM can achieve excellent surface finishes, achieving the highest quality finishes can require additional passes and slower cutting speeds, further increasing the machining time.
