SOMS3-430S Multi-Wire Saw – 3-Axis Oscillating 430mm Ingot Slicing Machine
The SOMS3-430S is a 3-axis single-station oscillating multi-wire saw built for precision thin-wafer production from 430mm ingots. Its mid-speed oscillating cutting mode delivers exceptional surface quality on ultra-hard materials, with a low center-of-gravity frame structure that minimizes vibration during extended production runs.
Key Features
- 🔹 Oscillating Cut Technology: 3-axis oscillating wire motion achieves superior surface flatness vs. standard forward-cut machines

WHY OSCILLATING CUT MODE MATTERS FOR SiC AND SAPPHIRE
SiC and sapphire are among the hardest commercial semiconductor materials. Standard forward-cut wire saws can experience wire bow, surface waviness, and accelerated wire wear. The SOMS3-430S oscillating mode:
- ✅ Distributes wire wear evenly along the diamond wire length
- ✅ Reduces maximum wire bow for better slice thickness uniformity
- ✅ Extends wire life by 20–40% compared to unidirectional cutting
FREQUENTLY ASKED QUESTIONS
Q: What is oscillating cut mode?
The wire moves with a small oscillating amplitude superimposed on the primary cutting direction. This distributes abrasive contact more evenly, reducing wire wear patterns and improving surface uniformity on hard materials.
Q: Can it process 4-inch and 6-inch SiC wafers?
Yes. The 430mm ingot capacity accommodates both 4-inch (100mm) and 6-inch (150mm) diameter SiC crystals with appropriate fixturing.
Q: Is it suitable for R&D or only production?
Both. The compact design makes it ideal for R&D labs. Many customers also run multiple SOMS3-430S units in parallel for scalable production.
