0.15mm Round Hole Wire EDM

Technical Advantages

The 0.15mm Round Hole Wire EDM service utilizes imported slow wire cutting equipment (such as Sodick and Charmilles), paired with brass/galvanized electrode wires with a diameter of 0.03-0.1mm. High-frequency pulse discharge removes metal, and an adaptive servo control system achieves precise hole forming through narrow slit and center positioning technology. Core precision indicators are industry-leading:

- Dimensional Accuracy: Slit width tolerance is strictly controlled within ±0.002mm, and slit length and depth dimensional errors are ≤0.003mm, meeting the precision-grade requirements of GB/T 13916-2008;

- Dimensional Accuracy: Hole diameter tolerance is strictly controlled within ±0.002mm, and hole depth dimensional errors are ≤0.003mm, meeting the precision-grade requirements of GB/T 13916-2008;

- Surface Quality: The surface roughness of the inner wall of the narrow slot can reach Ra0.2-0.4μm, presenting a uniform mirror effect. It can be directly assembled without subsequent polishing, avoiding workpiece wear or signal interference caused by surface roughness.

- Surface Quality: The surface roughness of the inner wall of the round hole can reach Ra0.2-0.4μm, presenting a uniform mirror effect. It can be directly assembled without subsequent polishing, avoiding component wear or media blockage caused by surface roughness.

- Geometric Tolerances: Slot straightness ≤0.001MM/100MM, parallelism ≤0.002MM, adjacent slot spacing tolerance ≤0.003MM, ensuring the consistency of the multi-slot structure.

- Geometric Tolerances: Roundness of round holes ≤0.001MM, concentricity ≤0.002MM, adjacent round hole center distance tolerance ≤0.003MM, ensuring the assembly consistency of the multi-hole structure.

- Processing stability: Utilizing a water-soluble working fluid and a closed-loop filtration system reduces electrode wire vibration and discharge interference, achieving a single narrow slit processing pass rate ≥99.2%, and batch production dimensional fluctuation ≤0.0015mm;
