Sintered Diamond Faceting Laps

Sintered Diamond Lap Disc

Solapas de facetado de diamantes sinterizados

Cuando tenga que cortar más facetas de las que puede contar, es hora de ir sinterizado. Estas son las vueltas de facetado más duraderas del mercado actual con una matriz de diamante de 3,5 mm y núcleos de acero rectificados con precisión. Las vueltas sinterizadas cortan tan agresivamente en la primera faceta como en la última.

Nuestro regazo de diamante sinterizado tiene una matriz de diamante de 5 mm de profundidad que expone nuevos puntos de corte a medida que se utilizan las ruedas. Los traslapes sinterizados se pueden revestir para exponer cristales adicionales para un corte más agresivo, pero no siempre es necesario revestir si se sigue un patrón de "lado a lado" al pulir para asegurar un desgaste uniforme. El equilibrio dinámico en la fábrica garantiza la concentricidad para un pulido suave y silencioso. El ancho de la matriz de diamante de 4 "es de 40 mm, el ancho de la matriz de diamante de 6" es de 55 mm, el ancho de la matriz de diamante de 8 "es de 75 mm, el ancho de la matriz de diamante de 10" es de 100 mm, el ancho de la matriz de diamante de 12 " es de 115 mm.


Sintered diamond faceting laps are known for their exceptional performance in the field of gemstone faceting and polishing. Their performance attributes make them highly sought after by gem cutters, lapidaries, and jewelry manufacturers. Here are the key performance characteristics of sintered diamond faceting laps:

  1. Precision Cutting: Sintered diamond faceting laps excel in precision cutting of gemstones. They allow gem cutters to create facets with exact angles and dimensions, resulting in symmetrical and well-proportioned gemstones.

  2. High-Quality Polishing: These laps are equally adept at polishing gemstone facets to achieve a brilliant and reflective surface. They produce a mirror-like finish that enhances a gemstone's optical properties, including its sparkle and fire.

  3. Durable and Long-Lasting: Sintered diamond laps are renowned for their durability and longevity. They can withstand extended use without significant wear, reducing the need for frequent replacement. This durability is essential in maintaining consistent performance over time.

  4. Reduced Heat Generation: These laps are designed to minimize heat generation during the faceting and polishing processes. This feature is crucial because excessive heat can damage or fracture gemstones, particularly heat-sensitive varieties.

  5. Uniform Facet Geometry: Sintered diamond faceting laps maintain consistent facet geometry throughout the cutting and polishing processes. This uniformity ensures that each facet is precisely aligned and contributes to the gem's overall brilliance.

  6. Versatility: They are versatile tools that can be used with various gemstone materials, including diamonds, sapphires, rubies, emeralds, and other precious and semi-precious stones. Their adaptability to different hardness levels and gem types is a key performance advantage.

  7. Enhanced Optical Properties: Sintered diamond faceting laps enhance a gemstone's optical properties by producing facets that reflect and refract light effectively. This results in a gemstone that exhibits exceptional brilliance, dispersion, and scintillation.

  8. Consistency: These laps offer consistency in facet dimensions and surface finishes across multiple gemstones. This consistency is crucial for producing gemstones that match in size and appearance for use in jewelry.

  9. Ease of Use: While expertise is required for gemstone faceting and polishing, sintered diamond faceting laps are designed to be user-friendly. They allow lapidaries to work efficiently and effectively.

  10. Quality Control: Sintered diamond laps play a significant role in maintaining high-quality standards in gem cutting and jewelry manufacturing. They help ensure that gemstones meet specific criteria for symmetry, dimensions, and surface finish.

  11. Optimal Performance: Gem cutters can achieve optimal performance with these laps when selecting the appropriate lap type, grit size, and lubrication method for the gemstone material being worked on.

Grit Range

Metal bonded diamond grinding wheels are available in various grit sizes to accommodate different grinding and surface finish requirements. The grit size determines the coarseness or fineness of the abrasive particles on the wheel's surface. Here are the typical grit size classifications for metal bonded diamond grinding wheels:

  1. Coarse Grits (e.g., 60, 80, 100):

    • Coarse grit wheels are used for rapid material removal and are suitable for rough grinding applications.

    • They are often used when the initial shape and dimension of the workpiece need significant adjustment.

    • Coarse grit wheels leave a rougher surface finish.

  2. Medium Grits (e.g., 180, 220):

    • Medium grit wheels strike a balance between material removal and surface finish.

    • They are suitable for general-purpose grinding tasks where both removal rates and surface quality are important.

    • Medium grit wheels produce a moderate surface finish.

  3. Fine Grits (e.g., 360, 600):

    • Fine grit wheels are used for precision grinding applications where surface finish is critical.

    • They excel at producing smooth and fine surface finishes while still removing material effectively.

    • Fine grit wheels are commonly used for applications that require high precision and tight tolerances.


Sintered diamond faceting laps are specialized tools used primarily in the gemstone and jewelry industry for faceting and polishing gemstones:

  1. Gemstone Faceting: The primary application of sintered diamond faceting laps is in the art of gemstone faceting. Gem cutters and lapidaries use these laps to cut and shape raw gemstones into intricate and precise geometrical patterns, known as facets. Faceting enhances the brilliance, fire, and overall visual appeal of gemstones.

  2. Gemstone Polishing: After initial faceting, sintered diamond faceting laps are employed for polishing the facets of gemstones. Polishing is a critical step that gives gemstones their signature sparkle and luster. The laps help achieve a mirror-like finish on the facets, enhancing the gem's optical properties.

  3. Jewelry Manufacturing: Gemstones that have been precisely faceted and polished using sintered diamond laps are widely used in the jewelry manufacturing industry. These gemstones are incorporated into various jewelry pieces, including rings, necklaces, earrings, bracelets, and brooches, to create stunning and valuable jewelry.

  4. Gemological Education: Sintered diamond faceting laps are also used in gemological education and training programs. Aspiring gemologists and lapidaries use these laps to learn the art of gemstone faceting, enabling them to gain hands-on experience in shaping and polishing gemstones.

  5. Custom Gem Cutting: Some lapidaries offer custom gem cutting services for clients who want unique and personalized gemstones for their jewelry. Sintered diamond faceting laps are essential tools for creating custom-cut gemstones to meet specific design requirements.

  6. Gemstone Repair and Restoration: In cases where damaged or worn gemstones require repair or restoration, sintered diamond faceting laps can be used to re-cut and re-polish the damaged facets, restoring the gemstone's beauty and value.

  7. Artistic and Creative Projects: Beyond traditional jewelry making, sintered diamond faceting laps can be used for artistic and creative projects that involve incorporating faceted gemstones into sculptures, decorative pieces, and other art forms.

  8. Gemstone Evaluation: Gemologists and appraisers use sintered diamond faceting laps to evaluate and assess the quality, clarity, and cut of gemstones. The precision of the faceting and polishing helps determine a gemstone's value and authenticity.

  9. Specialty and Rare Gem Cutting: These laps are often used for cutting and shaping specialty gemstones and rare finds. Some gemstones have unique optical properties or require specific cutting techniques, and sintered diamond faceting laps are essential for such tasks.


The diameter, thickness (or height), and hole size of sintered diamond faceting laps can vary depending on the lap's design, intended application, and manufacturer. These specifications can be customized to suit different gemstone cutting and polishing needs. Here are some common diameter, thickness, and hole size ranges for sintered diamond faceting laps:
