Wire EDM Services
High‑accuracy wire cutting for complex geometries, burr‑free finishes, and tight tolerances that traditional CNC machining can’t achieve. Ideal for aerospace, medical, automotive, and industrial components made from hard or exotic metals.
Wire EDM Machining Services
In high-stakes manufacturing, traditional CNC tools often reach their physical limits when faced with ultra-hard materials or intricate internal geometries that require absolute structural integrity. XTPROTO eliminates these constraints through advanced Wire Electrical Discharge Machining (EDM), a non-contact spark-erosion process that ignores material hardness to achieve repeatable accuracy up to ±2 µm (0.0001″). By utilizing specialized wire diameters as small as 20 µm (0.0008″), we can execute complex profiles, razor-sharp internal corners, and narrow slots in materials such as tungsten, carbide, tool steel, and titanium—features that are physically impossible to produce with conventional milling. The result for our customers in the medical, aerospace, and electronics sectors is a seamless transition from specialized prototypes to consistent production runs, delivering high-performance components with flawless surface finishes and micron-level detail that perform exactly as intended in the field.

Wire EDM Capabilities
Maintaining dimensional stability and surface integrity in thick or ultra-hard metal sections is a persistent challenge for standard machining, often leading to tool deflection and thermal distortion. XTPROTO eliminates these manufacturing risks by deploying advanced 4-axis Wire EDM technology capable of processing workpieces up to 16″ thick with a repeatable accuracy of ±2 µm (0.0001″). Our facility utilizes high-performance submerged cutting systems and auto-threading technology to ensure maximum thermal stability, allowing us to execute intricate contours and high-taper geometries that remain perfectly consistent across every part. By integrating small-diameter wires (0.004″) with sophisticated multi-pass power supplies, we achieve superior surface finishes and micron-level detail even during complex interrupted cuts. The result for our customers is a high-efficiency production model that supports everything from specialized prototypes to continuous “lights-out” high-volume manufacturing. This systematic approach maximizes material utilization and drastically reduces lead times, delivering production-ready components that meet the most rigorous aerospace and medical standards with absolute precision.
Quality Standards & Certifications
In high-precision Wire EDM, even a micron-level deviation can lead to catastrophic assembly failure or compromised mechanical performance in the field. XTPROTO eliminates these quality risks by integrating a rigorous ISO 9001:2015 certified quality management system into every stage of our production workflow. From initial material verification to final dimensional inspection, we employ advanced metrology tools—including CMM (Coordinate Measuring Machines), SPC monitoring, and high-resolution optical inspection systems—to verify that every complex contour meets your exact ±2 µm (0.0001″) specifications. By maintaining strict process control and comprehensive Quality Assurance procedures, we ensure absolute batch-to-batch consistency and structural reliability. The result for our customers is the delivery of high-performance components that not only meet but exceed the most demanding industry standards, providing total confidence in your most critical engineering applications.
Wire EDM Design Considerations
- Material & Hardness
Traditional tools struggle with hard alloys. Wire EDM uses spark erosion to cut any conductive material—from tool steel to carbide—with zero mechanical stress and total structural integrity. - Micro Internal Radii
Standard mills cannot cut sharp internal corners. Using wires as fine as 20 µm (0.0008″), we achieve near-zero radii and micro-slots that are physically impossible for conventional machining.
- Thin-Wall Stability
Cutting pressure often deforms delicate walls. As a non-contact process, Wire EDM produces high-aspect-ratio features without bending, maintaining a precise ±2 µm accuracy across the profile. - Thickness & Straightness
Maintaining verticality in thick parts is a challenge. Our systems handle up to 16″ thickness with submerged cutting, ensuring thermal stability and perfect vertical alignment for even the heaviest sections.

What Is Wire EDM Machining & How It Works
Wire EDM machining is a precision process that uses a thin, electrically charged wire to cut electrically conductive metals without direct contact, producing parts with sharp corners, intricate angles, and complex geometries without deformation or mechanical stress. The cutting occurs in a dielectric fluid, which protects the workpiece, removes debris, and stabilizes temperature for high-accuracy results. This method is ideal for hard or exotic metals such as stainless steel, nickel alloys, tool steel, titanium, and carbide. With full CNC control along X and Y axes, Wire EDM enables tight tolerances, high repeatability, and consistent surface quality for prototypes, small-batch runs, or high-volume production. Our experienced team works directly with your designs to ensure every part meets your exact precision, tolerance, and performance requirements, making Wire EDM a reliable choice for demanding aerospace, medical, and industrial applications.

Limitations Of Wire EDM
- Conductive Materials Only:Wire EDM can only machine electrically conductive materials, such as metals and certain alloys.
- Slower Cutting Speed:Compared with conventional CNC machining, laser cutting, or waterjet cutting, wire EDM is generally slower for simple parts.
- Recast Layer Formation:A thin heat-affected or recast layer may form along the cut edge and sometimes requires secondary finishing.
- Specialized Setup Required:Achieving optimal results often requires experienced operators and precise programming.
