HOW TO PROCESS

Application Process

In the Stone & Construction industry, Crownkyn supplies diamond-based superhard material solutions for cutting, grinding, profiling, lapping, and surface finishing of natural and engineered stone. Product selection and grit sizing are matched to stone hardness, abrasiveness, thermal load, and processing stage, helping you maintain stable cutting performance, long tool life, and consistent surface quality in high-duty industrial environments.

Cutting and Primary Shaping

Stone cutting operations are conducted under extremely harsh conditions, including heavy dust, limited cooling, continuous impact, and high thermal load. Saw Grit Monocrystalline Diamond Powder and Coated Diamond Powder are the core solutions for saw blades and wire saws, ensuring sharp cutting edges, thermal stability, and reliable segment performance during long production cycles.

Block cutting & slab sawing: 30/40–40/50 mesh for high efficiency and stable kerf
General stone cutting: 40/50–60/80 mesh for balanced speed and tool life
Highly abrasive or high-load cutting (e.g., granite, quartzite): Ti/Ni-coated diamond to resist thermal damage and enhance grit retention, ensuring stable cutting throughout blade life

Typical applications: Granite blocks, marble slabs, engineered quartz, sintered stone panels.

Grinding and Profiling

Grinding and profiling processes focus on thickness control, shape accuracy, and preparation for subsequent polishing steps. Wheel Grit Monocrystalline Diamond Powder offers stable grinding behavior and controlled wear, while Crushed Diamond Powder is preferred for rapid stock removal in resin-bond and metal-bond grinding tools.

Rough grinding & calibrating: 60/80–80/100 mesh crushed diamond for aggressive, fast stock removal and plane formation
Intermediate grinding: 100/120–140/170 mesh monocrystalline diamond for profile accuracy and dimensional stability
Edge profiling & contouring: Wheel grit monocrystalline diamond for consistent shape retention in long runs

Typical applications: Stone tiles, countertops, steps, architectural stone components.

Lapping and Polishing

Stone lapping and polishing aim to refine surface texture, improve gloss, and achieve uniform visual quality without surface burns or random scratches. Micron Diamond Powder, Diamond Slurry, and Diamond Paste are used in controlled sequences to ensure predictable surface evolution and high repeatability.

Pre-polishing: 20–40 μm to remove grinding marks and prepare the surface
Fine polishing: 6–14 μm for surface smoothing and gloss development
Final polishing: 1–3 μm or sub-micron grades for high-gloss finishes

Typical applications: Polished marble, granite tiles, quartz surfaces, decorative stone panels.

Fine Finishing and Surface Enhancement

For premium stone products requiring superior appearance and surface consistency, fine and sub-micron diamond materials play a critical role. Micron and sub-micron Diamond Powder supports controlled material removal while minimizing subsurface damage.

Fine surface finishing: ≤1 μm diamond grades for smooth, uniform surfaces
Gloss enhancement: Sub-micron diamond treatments for improved light reflection
Wear surface preparation: Diamond micro-powder for high-traffic stone products

Typical applications: High-end architectural stone, decorative panels, engineered stone surfaces.
