Custom Precision Sapphire Blade, Sapphire Cutting Blade for Industrial Cutting

High‑precision sapphire blades are processed from high‑purity synthetic sapphire crystal. Featuring ultra‑hardness, sharp cutting edge, excellent wear resistance, chemical inertness and low friction coefficient.

These thin sapphire blades can be manufactured into strip, rectangular and custom special shapes. Edges can be sharpened to precise cutting edges. Surface can be lapped or optical polished. Custom dimensions, thickness, edge angles and chamfer processing are available per customer drawings.

Sapphire blades outperform metal blades with non‑rusting, non‑contamination and long service life. Widely applied for film slitting, fiber cutting, biological sample slicing, laboratory cutting and special‑industry precision trimming. Strict quality control for edge sharpness, dimensional tolerance and surface finish. Support sample trial and mass‑volume production.
