RS Precision Industries delivers high-accuracy Wire EDM machining and integrated EDM solutions for complex, mission-critical components. As a dedicated sub-capability within our CNC EDM offering, our Wire EDM services are engineered for parts that demand extreme precision, tight tolerances, and intricate geometries that conventional machining cannot achieve.
With a fully equipped EDM department, including 8 Mitsubishi MV1200 wire EDM machines and a Current EDM CT300 Hole Popper, we provide scalable, repeatable results across prototype and production volumes.
High-Precision Wire EDM Machining
Wire EDM is a non-contact machining process that uses controlled electrical discharges to cut conductive materials with exceptional accuracy. Unlike traditional cutting methods, there is no mechanical force applied to the part, making it ideal for delicate, hardened, or high-value materials.
At RS Precision, our Wire EDM services are capable of:
- Holding tolerances to ± .0001 inch
- Producing sharp internal corners and fine features
- Machining hardened materials without distortion
- Delivering burr-free finishes with minimal secondary work
- Supporting high-aspect-ratio cuts and thin-wall geometries
This process is particularly effective for aerospace, defense, medical, and spacecraft components where precision and consistency are non-negotiable.
Hole Popper (Fast Hole EDM) Capabilities
Our Hole Popper system (the CT300) adds critical functionality to our EDM workflow. Fast hole EDM is used to drill extremely small, deep holes with high speed and accuracy, often serving as the starting point for wire EDM operations.
Capabilities include:
- Hole diameters as small as .008”
- High aspect ratios up to 100:1
- Rapid drilling in hard or exotic materials
- Ideal for start holes, cooling channels, and micro-features
Originally developed to support wire threading, hole popping is now widely used for finished features in high-performance parts.
Integrated EDM & Machining, A True One-Stop Shop
What separates RS Precision is not just our EDM capacity, but our ability to deliver complete parts in-house. Many components require multiple processes to achieve final geometry and performance. Instead of outsourcing, we manage everything under one roof.
Our full-service capabilities include:
- CNC Sinker EDM
- CNC Milling (horizontal & vertical)
- CNC Turning
- CNC Surface Grinding
- Engineering, fixturing, and secondary operations
This integrated approach reduces lead times, eliminates vendor handoffs, and ensures tighter process control from start to finish. For customers with complex, multi-step requirements, this is a significant advantage.
Built for Complex, High-Performance Applications
EDM machining is often the only viable method for producing features such as:
- Deep slots and narrow cavities
- Blind internal geometries
- Thin or fragile components
- Precision dies, tooling, and medical parts
Because EDM is not limited by tool geometry, it opens up design flexibility that traditional machining cannot match.
