Sapphire slicing has become a critical procmess in the manufacturing of high-performance aerospace and defense components. From the infrared guidance domes of tactical missiles to the sapphire protective covers on advanced satellite sensors, these components are the “eyes” of modern aerospace technology. However, due to its extreme hardness—second only to diamond—サファイアのスライス presents a unique set of engineering challenges. Traditional processing methods often lead to high scrap rates and surface imperfections, making the choice of cutting technology a decisive factor in mission success.
The Challenge: Why Precision Sapphire Slicing is Difficult
In the aerospace industry, failure is not an option. Standard sawing techniques often struggle with the physical properties of sapphire (Al₂O₃ crystals), leading to several production bottlenecks during the サファイアのスライス phase:
- Edge Chipping: Severe breakage often occurs at the exit point of the cut, which is unacceptable for optical-grade components.
- Sub-Surface Damage: Excessive mechanical stress during サファイアのスライス can create deep fractures that require hours of expensive, labor-intensive secondary polishing.
- Low Material Utilization: With the high cost of synthetic sapphire and specialized substrates like Gallium Nitride (GaN), every micron of material lost to kerf is a significant financial hit.
The Vimfun Solution: Redefining Sapphire Slicing Efficiency
Vimfun’s SG series of Endless Diamond Wire Saws provides a revolutionary approach to サファイアのスライス. By utilizing a continuous, unidirectional loop of diamond-impregnated wire, we offer a solution that prioritizes material integrity and throughput.
1. Unmatched Surface Quality and Reduced Polishing The high-speed stability of our endless wire ensures that the サファイアのスライス process produces a surface with minimal roughness (Ra). By maintaining a linear speed of up to 80 m/s, the wire performs a precise micro-grinding action rather than a high-impact cut. Many of our aerospace clients report a 40% reduction in secondary polishing time after switching to our technology, as the initial サファイアのスライス quality is significantly higher than reciprocating alternatives.
2. Superior Edge Integrity and Yield Rates One of the most praised features of our equipment is its ability to handle delicate exit-side transitions. Our specialized tensioning system (150-250N) ensures the wire remains perfectly stable throughout the サファイアのスライス cycle. This virtually eliminates exit-side chipping, ensuring that even ultra-thin sapphire wafers (under 0.5mm) remain intact and meet aerospace tolerances.
3. Optimized Material Utilization (Low Kerf Loss) When performing サファイアのスライス on high-value materials, kerf loss is a critical KPI. Our technology utilizes wire as thin as 0.3mm, resulting in a total kerf loss of only 0.35mm. This allows manufacturers to extract more usable slices from a single sapphire ingot or semiconductor boule, directly improving the bottom line of defense electronics projects.
