High-purity monocrystalline germanium is a typical hard and brittle material. Traditional machining methods easily cause cracks, chipping, or thermal damage. Our ZNC450 die sinker EDM provides a reliable solution for high-purity monocrystalline germanium precision drilling and high-precision machining. In the high-tech fields of semiconductor manufacturing, optical engineering, scientific research laboratories, and precision component production, high-purity monocrystalline germanium has become core materials with irreplaceable value. Endowed with excellent electrical conductivity, thermal stability, and infrared light transmittance, high-purity monocrystalline germanium is widely used in the production of infrared detectors, semiconductor chips, optical lenses, and precision scientific research instruments.
For enterprises engaged in high-purity monocrystalline germanium processing, achieving high-precision, damage-free machining of key processes—especially cavity machining and drilling—is the core demand to ensure product performance and market competitiveness.
1. Machining Difficulties of Germanium
High-purity monocrystalline germanium has three key traits: high hardness, high brittleness and low fracture resistance. It brings major processing challenges:
- Traditional cutting tools produce mechanical stress, easily causing material cracks and chipping
- Conventional laser processing creates thermal damage, ruining optical performance
- Standard methods cannot achieve high-precision micro drilling
2. Advantages of EDM for Germanium Machining
EDM (Electrical Discharge Machining) is a non-contact processing technology. It uses electric sparks to erode materials, perfectly fitting hard and brittle germanium:
