CNC Machining Parts
Wire EDM Parts
Custom parts cut by wire electrical discharge machining, where a thin electrically charged wire removes material by controlled spark erosion rather than by cutting force. Because there is no mechanical pressure on the workpiece and no heat affected cutting edge, wire EDM produces sharp internal corners, thin webs and hardened material geometries that milling cannot reach.
- Tool steel
- Titanium
- Brass
Product Overview
Custom parts cut by wire electrical discharge machining, where a thin electrically charged wire removes material by controlled spark erosion rather than by cutting force. Because there is no mechanical pressure on the workpiece and no heat affected cutting edge, wire EDM produces sharp internal corners, thin webs and hardened material geometries that milling cannot reach. Parts are produced to customer drawings.
Key Benefits
- Cuts fully hardened material after heat treatment, so parts do not distort in a later heat treat step
- Produces sharp internal corners and narrow slots that a milling cutter radius cannot make
- No cutting force on the part, so thin and delicate sections stay in tolerance
- Suited to tool steels, titanium, brass and copper that are difficult to machine conventionally
- Same process handles one off tooling and repeat production parts
Problems It Solves
- Geometry that a milling cutter cannot produce because of corner radius
- Parts that distort when machined soft and then hardened
- Thin walled components that deflect under conventional cutting force
- Hard materials that wear conventional tooling quickly
Where It Is Used
Applications And Buyers

Compared With The Alternatives
| CNC milling | Milling is faster and cheaper for open geometry in soft material; wire EDM wins on hardened material, sharp internal corners and thin sections. |
|---|---|
| Laser cutting | Laser is far quicker on sheet; wire EDM holds tighter tolerance and leaves no heat affected cut edge on thick or hardened stock. |
Use Guide
- Send a drawing marked with which tolerances actually drive function
- State the material condition, since cutting after hardening usually gives a better result
- Specify corner radius requirements, since wire EDM can hold very sharp corners
- Allow for start holes on closed internal profiles at the design stage
Questions
Questions Buyers Ask About This Product
Which materials can be cut by wire EDM?
Any electrically conductive metal, including tool steel, titanium, brass and copper. Hardened material is cut as readily as soft.
Can you cut parts after heat treatment?
Yes, and it is usually the better route because the part does not distort afterwards.
What do you need to quote?
A drawing or a step file, the material and condition, the quantity and the tolerances that matter.
Do you make punches and dies?
Yes, punches, dies and mould components are among the most common parts produced this way.
Is there a minimum order quantity?
No fixed minimum. One off tooling and repeat production runs are both quoted.
