High Accuracy CNC Wire EDM Parts with 0.002mm Precision and ±0.005mm Tolerance for Medical and Aerospace Applications

Electrical discharge wire cutting (wire-walking) is an electrothermal production process that uses electrical discharge to remove material from the workpiece. This advanced version of traditional EDM methods is compatible with nearly all conductive materials and can produce complex designs and shapes with exceptional precision.

Wire cutting is a non-contact reduction manufacturing process that uses charged fine wires and dielectric fluids to shape metal parts. This versatile precision machining process is ideal for manufacturing complex geometries, particularly in industries requiring strict tolerances like aerospace and medical.

Ideal for complex shaped parts with high precision requirements, particularly for custom automotive components.

Preferred for parts requiring excellent surface finish and precision, including engines, turbine blades, and landing gear components.

Perfect for complex medical parts requiring high precision, such as dental implants and syringe components.

• Aluminum: Excellent thermal and electrical conductivity. Requires proper operation to avoid gelatinous buildup during processing.
• Titanium: Well suited for EDM machining but requires deionized water as a medium to control heat generation.
• Steel: Requires heat management during processing but excellent for complex features.
• Brass: High tensile strength but requires slower cutting speeds due to its soft nature.

• High cutting precision with minimal need for additional processing
• Ideal for small parts and highly fine cutting projects
• Capable of manufacturing complex designs difficult for traditional CNC machining
• Produces clean cuts without burrs or deformations in a single processing stage
• Continuous processing without interruption

Besides Wire EDM, there are drilling EDM (using tubular electrodes for finer holes) and sink hole EDM (using shaped conductive metal electrodes).

Laser cutting uses a high-power thermal beam while wire-cut EDM uses electrical processing with a wire electrode.

Deionized water serves as an effective coolant with low carbon properties to regulate dielectric temperature.
