HOW TO PROCESS

Application Process

In the Glass & Gemstone industry, Crownkyn provides diamond-based superhard material solutions for cutting, grinding, shaping, lapping, and polishing of brittle, high-value materials. Product selection and grit sizing are matched to glass type, gemstone hardness, fracture behavior, and surface quality requirements, helping you achieve stable processing, high yield, and consistent quality for industrial and professional manufacturing.

Cutting and Rough Machining

Cutting and rough machining of glass and gemstones require superhard abrasives with extreme sharpness and controlled fracture behavior to minimize chipping and edge damage. Saw Grit Monocrystalline Diamond Powder and Coated Diamond Powder are the primary choices, delivering efficient cutting and clean edges in brittle materials.

Rough cutting and slicing: 40/50–60/80 mesh for high material removal efficiency
General cutting and shaping: 80/100–100/120 mesh for balanced speed and edge quality
Hard or impact-sensitive glass and gemstones: Coated diamond to improve grain retention and extend tool life

Typical applications: Optical glass blocks, architectural glass, sapphire blanks, gemstone rough stones.

Precision Grinding and Shaping

Precision grinding and shaping are essential for dimensional accuracy and surface consistency in glass and gemstone components. Wheel Grit Monocrystalline Diamond Powder ensures stable grinding performance, while Crushed Diamond Powder supports aggressive stock removal in early grinding stages.

Rough grinding: 80/100–120/140 mesh crushed diamond for rapid shape establishment
Semi-finish grinding: 140/170–200/230 mesh monocrystalline diamond for dimensional control
Profile grinding: Wheel grit monocrystalline diamond for stable contour accuracy

Typical applications: Glass lenses, gemstone facets, watch glass, decorative crystal components.

Lapping and Polishing

Lapping and polishing are critical to achieve high transparency, surface smoothness, and optical quality. Micron Diamond Powder, Diamond Slurry, and Diamond Paste provide controlled material removal without inducing subsurface damage.

Pre-lapping: 15–30 μm for surface leveling and flatness correction
Fine lapping: 6–14 μm to remove grinding marks
Final polishing: 1–3 μm or finer for high-gloss, optical-grade surfaces

Typical applications: Optical lenses, gemstone polishing, glass panels, precision crystal parts.

Ultra-Fine Finishing and Surface Engineering

For premium glass and gemstone products requiring mirror finishes and superior visual quality, advanced finishing materials are applied. Nano Diamond Powder and fine micron diamond grades enable ultra-smooth surfaces with minimal damage.

Ultra-fine finishing: ≤1 μm and nano-scale diamond for ultra-smooth, high-clarity surfaces
Surface strengthening: Diamond micro-powder to improve scratch resistance
Thermal management: Thermal conductive diamond for specialty glass components requiring heat dissipation

Typical applications: High-end optical glass, sapphire windows, luxury gemstone products, precision display glass.
