HOW TO PROCESS

Application Process

In the ferrous metals industry, Crownkyn provides diamond and CBN superhard material solutions for cutting, grinding, finishing, and surface engineering. Product selection and grit sizing are matched to material chemistry, hardness, and thermal conditions to ensure stable performance, long tool life, and process consistency for industrial users.

Cutting and Rough Machining

Cutting and rough machining of ferrous metals require superhard materials with high thermal stability and chemical inertness. Monocrystalline CBN Powder is the primary choice for steels and cast irons, providing stable wear and cost-effective performance. Coated Diamond Powder is limited to specialized conditions such as excellent cooling, light cuts, or non-ferrous coatings, while CBN remains the superior and more economical solution for most steel and iron machining.

Rough cutting and turning: 40/50 to 60/80 mesh for high material removal and thermal stability
General machining: 80/100 to 100/120 mesh for balanced cutting efficiency and dimensional control
Interrupted or high-load machining: CBN-dominant grades for improved grain retention and impact resistance

Typical applications: Hardened steel shafts, cast iron housings,alloy steel components, forged parts.

Precision Grinding and Shaping

Precision grinding and shaping of ferrous metal components mainly use Monocrystalline CBN Powder and Micron CBN Powder as the primary abrasives in resin-bond and vitrified wheels, ensuring profile accuracy, thermal stability, and long wheel life.

Rough grinding: 80/100 to 120/140 mesh for efficient stock removal
Semi-finish grinding: 140/170 to 200/230 mesh for improved dimensional accuracy
Profile grinding: CBN-dominant grades for stable contour control

Typical applications: Gears, bearing rings, crankshafts, camshafts, transmission components.

Lapping and Polishing

Lapping and polishing of ferrous precision parts use Micron CBN Powder, Micron Diamond Powder, and Diamond Slurry and Paste to achieve controlled surface roughness and functional accuracy.

Pre-lapping: 15–30 μm for surface correction
Fine lapping: 6–14 μm to remove grinding marks
Final polishing: 1–3 μm or finer for high-precision functional surfaces

Typical applications: Bearing raceways, sealing surfaces, valve components, precision molds.

Ultra-Fine Finishing and Surface Engineering

For wear-critical and high-load ferrous components, Nano Diamond Powder, Micron Diamond Powder, and functional superhard materials are applied to enhance surface integrity, fatigue life, and thermal performance.

Ultra-fine finishing: ≤1 μm for smooth surfaces and reduced friction
Surface strengthening: Diamond micro-powder blasting to improve wear resistance
Thermal management: Thermal conductive diamond for heat dissipation in functional or composite systems

Typical applications: Gear teeth, bearing journals, hydraulic components, high-load sliding parts.
