Why This Cutting Guide Matters
Hard and brittle materials pose unique challenges — micro-cracks, surface chipping, and thermal stress can easily occur when improper parameters are applied.
This technical guide summarizes:
Recommended wire diameters (0.35 – 0.8 mm) and wire speeds up to 80 m/s
Optimized feed rates for each material type
Cooling and dust-extraction methods to protect both product and equipment
Comparative data versus traditional saws (inner-diameter, band saw, etc.)
Engineers can use these verified parameters as a benchmark to improve precision and efficiency.
Preview Table
| Material | Wire Diameter | Wire Speed | Feed Rate | Cooling Method |
|---|---|---|---|---|
| Quartz | 0.6 mm | 80 m/s | 1.5 mm/s | Air suction |
| Graphite | 0.65 mm | 80 m/s | 1.6 mm/s | Dust extractor |
| Sapphire | 0.5 mm | 75 m/s | 1.2 mm/s | Air suction |
| Silicon Carbide | 0.45 mm | 70 m/s | 1.0 mm/s | Air jet |
| Ceramics | 0.6 mm | 78 m/s | 1.4 mm/s | Air suction |
