Product Description

Ultra-precision Process

Sanluo Precision's processing plant has mastered the ultra-precision process of micro electrical discharge machining. WEDG wire grinding: tungsten wire EDM wire grinding with φ0.01mm to φ0.05mm is used to process micro-shaft electrodes with a diameter of φ0.02mm to φ0.5mm, diameter accuracy ±0.001mm, cylindricity 0.002mm, surface roughness Ra 0.1μm. Micro-energy discharge: single pulse energy is 10⁻⁸ to 10⁻¹⁰ joules, discharge spot diameter is less than 3μm, material is removed at the atomic level, and the surface quality is good. Precision servo: nanometer-level feed resolution, adaptive gap control, real-time detection of discharge status. Constant temperature and humidity: the processing environment temperature is 20±0.1℃, humidity is 50±2%, active vibration isolation to ensure stability. Online detection: laser measurement, white light interferometer, atomic force microscope, with an accuracy of up to nanometer level.
