HOW TO PROCESS

Application Process

In the Composite Materials industry, Crownkyn provides diamond-based superhard material solutions for cutting, trimming, grinding, lapping, polishing, and surface engineering. Product selection and grit sizing are matched to composite structure, fiber type, matrix material, and surface integrity requirements, helping you achieve damage-free processing, stable tool life, and consistent quality in industrial composite manufacturing.

Cutting and Trimming

Cutting and trimming of composite materials require extremely sharp, wear-resistant abrasives to avoid delamination, fiber pull-out, and matrix degradation under intermittent and abrasive cutting conditions. Saw Grit Monocrystalline Diamond Powder and Coated Diamond Powder are the core solutions for composite cutting tool manufacturing.

Panel cutting & rough trimming: 40/50–60/80 mesh for efficient removal and controlled edges
Precision trimming & contour cutting: 80/100–100/120 mesh for clean edges and reduced fiber damage
High-performance CFRP or abrasive composites: Ti/Ni-coated diamond to prevent thermal degradation, maximize grit retention, and eliminate delamination

Typical applications: CFRP panels, GFRP laminates, sandwich composites, structural composite blanks.

Precision Grinding and Shaping

Precision grinding and shaping of composite components focus on dimensional control and surface integrity without inducing subsurface damage. Wheel Grit Monocrystalline Diamond Powder provides stable grinding behavior, while Crushed Diamond Powder supports aggressive stock removal in resin-bond grinding tools.

Rough grinding: 80/100–120/140 mesh crushed diamond for fast stock removal and shape formation
Semi-finish grinding: 140/170–200/230 mesh monocrystalline diamond for improved dimensional accuracy
Profile grinding: Wheel grit monocrystalline diamond for stable contour control and shape retention

Typical applications: Composite structural parts, reinforced panels, precision composite components.

Lapping and Polishing

Lapping and polishing of composite materials aim to improve surface smoothness and prepare parts for bonding, coating, or assembly. Micron Diamond Powder, Diamond Slurry, and Diamond Paste are used to achieve controlled surface refinement with minimal fiber damage.

Pre-lapping: 15–30 μm for surface leveling and defect removal
Fine lapping: 6–14 μm to eliminate grinding marks
Final polishing: 1–3 μm or finer for smooth, functional composite surfaces

Typical applications: Composite bonding interfaces, aerodynamic surfaces, hybrid composite components.

Ultra-Fine Finishing and Surface Engineering

For high-performance composite components requiring superior surface integrity for bonding and coating, advanced finishing materials are essential. Nano Diamond Powder and advanced micron-grade diamond materials support ultra-smooth surface generation and functional enhancement.

Ultra-fine finishing (bonding-critical): ≤1 μm and nano diamond; polycrystalline diamond micron powder for uniform, resin-rich bonding surfaces
Surface strengthening: Diamond micro-powder to enhance wear resistance of composite interfaces
Thermal management: Thermal conductive diamond for heat-dissipating composite structures

Typical applications: High-end CFRP structures, bonded composite assemblies, functional composite systems.
