Product Description

Processing Technology and Precision Advantages

The 0.15mm Narrow Slot Wire EDM 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 narrow slot forming. Core precision indicators are industry-leading:

Dimensional Accuracy: Slot width tolerance is strictly controlled within ±0.002mm, and slot length and depth errors are ≤0.003mm, meeting GB/T standards. Standard 13916-2008 Precision Grade Requirements.Surface Quality: The surface roughness of the inner wall of the narrow slot can reach Ra0.2-0.4μm, presenting a uniform mirror effect. Direct assembly is possible without subsequent polishing, avoiding workpiece wear or signal interference caused by surface roughness.

Geometric Tolerances: Slot straightness ≤0.001MM/100MM, parallelism ≤0.002MM, adjacent slot spacing tolerance ≤0.003MM, ensuring consistency of the multi-slot structure.Machining Stability: Utilizing water-soluble working fluid and a closed-loop filtration system reduces electrode wire vibration and discharge interference. Single slot machining pass rate ≥99.2%, batch production dimensional fluctuation ≤0.0015MM.

Xincheng is a professional CNC machining factory and also a manufacturer and supplier of processed parts in China. Welcome to consult and purchase.
