HOW TO PROCESS

Application Process

In the geological drilling industry, Crownkyn provides diamond-based superhard material solutions for drilling, cutting, wear control, and surface engineering. Product selection and grit sizing are matched to formation hardness, abrasiveness, impact load, and thermal conditions to ensure stable penetration rates, long tool life, and predictable performance for industrial drilling applications.

Drilling and Cutting

Drilling and cutting in geological exploration demand superhard materials with high impact strength, wear resistance, and thermal stability. Monocrystalline Diamond Powder, Crushed Diamond Powder, and Coated Diamond Powder are widely used in impregnated bits, surface-set cutters, and advanced cutting elements.

Soft to medium formations: 30/40 to 40/50 mesh for high penetration efficiency

Medium-hard formations: 40/50 to 60/80 mesh for balanced speed and wear resistance

Hard, abrasive, or high-temperature formations: Metal-coated (Ti/Ni) diamond grades forming a metallurgical bond with the matrix to prevent grain pull-out and protect diamonds from thermal degradation

Typical applications: Core drilling bits, exploration tools, and PDC cutter manufacturing using high-purity, high-strength diamond micron powders with controlled crystal morphology.

Impregnated Bit Design and Wear Control

In impregnated diamond bits, controlled diamond exposure is critical to maintaining penetration throughout the drilling cycle. Crushed Diamond Powder provides sharp, aggressive cutting edges for rapid rock removal, while Monocrystalline Diamond Powder delivers consistent wear behavior and longer service life in harder formations.

High penetration designs: 40/50 to 60/80 mesh crushed diamond for sharp cutting and rock removal
Balanced wear designs: 60/80 to 80/100 mesh monocrystalline diamond for stable, predictable wear
High-abrasion formations: Coated diamond powders to improve retention in cobalt or copper matrices

Advanced designs often mix or layer diamond types to create a self-sharpening wear gradient for consistent drilling performance.
Typical applications: Mineral exploration bits, geothermal tools, foundation drilling systems,deep-hole drilling equipment.

Lapping and Polishing of Drilling Wear Components

Precision lapping and polishing are applied to critical friction and sealing interfaces in drilling equipment using Micron Diamond Powder, Diamond Slurry, and Diamond Paste. These processes reduce friction, improve sealing reliability, and extend component life under extreme operating conditions.

Pre-lapping: 15–30 μm for correction of wear interfaces

Fine lapping: 6–14 μm to improve contact uniformity

Final polishing: 1–3 μm or finer for low-friction surfaces

Typical applications: Sealing faces of downhole motors, bearing races in rotary steerable systems, wear surfaces of drill string connectors, and critical coring tool interfaces.

Advanced Surface Engineering and Thermal Management

For extreme drilling environments, advanced diamond materials are selectively applied to address localized wear and heat challenges.

Surface strengthening:
Nano Diamond Powder coatings or impregnations for thrust bearings in high-speed turbo-drills to improve wear resistance and fatigue life

Thermal management: Thermal Conductive Diamond composites integrated into PDC cutter faces for geothermal drilling, delaying thermal fatigue where cooling is limited

Typical applications: High-speed downhole motors, geothermal drilling systems, high-load cutting elements.
