Introduction
Coupe silicon carbide (SiC) rings, especially along the inner circular edge, poses unique challenges due to the material’s extreme hardness, brittleness, and often complex geometry. Whether used in mechanical seals, thermal insulation systemsou semiconductor furnace components, the need for a precise and non-destructive cutting method is critical.
This is where the scie à fil diamanté sans fin technology comes in.
Why Is Cutting the Inner Circle So Difficult?
Traditional tools like blades, waterjets, or grinding wheels often struggle to:
- Reach and cut the inner circumference of a ring structure
- Maintain précision dimensionnelle without introducing cracks
- Avoid thermal damage or contamination on sensitive SiC surfaces
Le inner circle of a SiC ring may need to be cut open, enlarged, or separated for:
- Fitting assemblies
- Customized mechanical tolerances
- Creating slotted or notched ring structures
- Reducing internal stress after sintering
Endless Diamond Wire Saw: A Cleaner, Smarter Alternative
Unlike reciprocating spool wire saws or rotary blades, an scie à fil diamanté sans fin uses a closed-loop wire to achieve continuous, high-speed, and flexible cutting.
Advantages in SiC Ring Inner Cutting:
| Fonctionnalité | Benefit |
|---|---|
| 🔁 360° endless loop | Seamless motion without reversal; smoother cuts |
| 🔍 Fine wire (0.35–0.6 mm) | Minimal kerf loss; ideal for precision inner shapes |
| ❄️ Coupe à froid | No heat-affected zone (HAZ); preserves material properties |
| 🚫 Low vibration | Prevents edge chipping or microcracks |
| ⚙ CNC programmable | Supports circular slots, grooves, and contour followin |
Typical Applications of SiC Ring Cutting
Even if the final industry isn’t known, common end uses include:
- Mechanical seal rings (for pumps, compressors)
- SiC hot zone support rings (used in crystal growth furnaces)
- Plasma etching components in semiconductor tools
- High-temperature ceramic insulators and guide rings
- Customized ring electrodes for PVD/CVD coating
