High-Performance Diamond Solutions for Aero Engine and Airframe Finishing

Advanced Diamond Solutions for the Aerospace Industry

Synthetic diamond powder is essential for achieving machining efficiency and surface integrity in the aerospace industry.
From grinding and honing nickel-based superalloys and titanium to drilling and finishing CFRP and CMC structures, as well as polishing optical glass and sapphire for avionics, synthetic diamond provides exceptional hardness, wear resistance and thermal stability to handle difficult materials with confidence.

Crownkyn’s precision-graded synthetic diamond powders offer stable quality, uniform particle size distribution and clean morphology. Available from mesh to micron in angular or blocky types, and optional Ni, Cu or Ti coatings, our powders help you increase removal rates, extend wheel life and reach low Ra finishes with tight dimensional control. With dependable supply and technical support, we are a trusted choice for aero-engine, airframe and MRO applications.

Application in Aerospace Industry

In the aerospace industry, where precision, reliability and traceability are critical, Crownkyn’s synthetic diamond powders help you cut, grind, polish and perform surface enhancement on advanced materials including nickel based superalloys, titanium alloys, CFRP and CMC structures, optical glass and sapphire, with exceptional stability. Tight particle size control, clean morphology and consistency from batch to batch deliver longer tool life, higher throughput and low Ra finishes, while our dependable supply supports both high volume production and specialised MRO or prototype work so you meet dimensional targets and aerospace quality standards at every stage.

Cutting Process

In aerospace manufacturing, PCD tools are used for machining titanium alloys, high-temperature alloys, and composite materials, while PCBN tools are applied to the machining of hardened steels and heat-resistant alloys.
  • Titanium and high-temp alloys (engine blades, turbine discs): PCD tools offer over 10× tool life vs. carbide for precise, stable machining.
  • Composites (fuselage, wing structures): PCD tools reduce delamination and burrs when drilling and milling CFRP.
  • Hardened steels (landing gear, gears): PCBN tools achieve fine finishes on ultra-strong steels like 300M, with Ra as low as 0.4 μm.
  • Heat-resistant alloys (combustion chambers): PCBN tools cut efficiently with less thermal damage.

Grinding Process

In aerospace machining, diamond grinding wheels are used for machining ceramic and carbide components, while CBN grinding wheels are applied to grinding engine gears and turbine shafts, ensuring micron-level precision for critical parts.
  • Ceramic components (sensors, radar windows – Al₂O₃, SiC): Diamond grinding wheels enable high-precision machining with minimal edge chipping.
  • Cemented carbide (fuel nozzle micro-holes): Diamond wheels achieve ±2 μm hole tolerance for consistent flow and combustion performance.
  • Engine bearings and gears (carburised steels): CBN wheels support high-speed grinding with excellent roundness control.
  • Turbine shafts: CBN wheels deliver ultra-fine surface finishes (Ra < 0.1 μm) for enhanced fatigue resistance.

Polishing Process

In aerospace manufacturing, advanced polishing techniques are applied to critical components; diamond-based materials enable high-precision surface finishing that significantly enhances component performance.
  • Hydraulic valve spools (mirror finishing): Diamond lapping paste delivers nanometre-level accuracy and lowers leakage.
  • Turbine blade film-cooling holes: Nano-diamond slurry removes the recast layer, boosting cooling efficiency by ~15%.
  • Optical navigation lenses: MRF combined with diamond micro-powder improves surface figure and finish.

Suface Enhancement

For surface strengthening of critical aerospace components, diamond micro-powder blasting and CBN roller burnishing are primarily employed, significantly improving the fatigue strength and wear resistance of core parts such as engine blades and aerospace bearings.
  • Turbine blade anti-fatigue treatment: nano-diamond abrasive blasting to extend the fatigue life of titanium blades and improve durability.
  • Aerospace aluminium alloy strengthening: diamond micro-powder blasting to raise surface hardness and wear resistance.
  • Aerospace bearing strengthening: CBN roller burnishing to increase residual compressive stress and enhance fatigue strength.
