Precision Machining Capabilities for Si₃N₄
Overcoming brittleness through advanced multi-axis diamond grinding expertise
Complex Micro-Feature Grinding
Multi-axis CNC grinding for intricate geometries, micro-slots, deep pockets, and fine details while preventing edge chipping and subsurface damage.
Thread Milling & Tapping
Precision internal and external thread grinding for Si₃N₄ components, enabling direct ceramic threading without metal inserts for high-temperature assemblies.
Deep Slot & Groove Machining
Diamond wheel profiling and plunge grinding for deep slots (aspect ratios > 5:1) with clean bottoms and vertical sidewalls.
Ball & Sphere Grinding
Precision grinding of Si₃N₄ balls and spherical components for bearing applications, achieving G10 grade sphericity and sub-micron surface finish.
Thin-Wall Component Machining
Specialized fixturing and optimized grinding parameters enable thin-wall Si₃N₄ structures (down to 0.5 mm) without fracture or distortion.
Complete Metrology Validation
100% inspection using calibrated CMM, optical comparators, and surface roughness testers with comprehensive FAI/OQC documentation.
