SND-G60 Metal Bond Synthetic Diamond Powder (MBD10 Equiv.) – 80/100–325/400 Mesh for High-Toughness Grinding & Polishing

 

SND-G60 Fine-Size Metal Bond Synthetic Diamond Powder (Equiv. MBD10)

 

 

Description:

SND-G60 is crafted from ultra-pure synthetic diamond (≥99.8% carbon content) with a cuboctahedra-dominant crystal structure. The polished faces and thick, uniform edges provide exceptional toughness, wear resistance, and consistent performance, reducing the micro-fractures commonly seen in lower-grade powders. SND-G60 has a high toughness (Vickers hardness: 7,200–7,500 HV) and thermal stability (up to 900°C), making it ideal for high-grinding-rate applications in stone, ceramic, and optical glass processing, where both durability and precision are required.

Optimized for premium NA/EU applications, SND-G60 maintains sharpness during granite polishing (e.g., NA residential kitchen countertops, 2cm-thick granite slabs) and ceramic tile edge finishing (e.g., EU porcelain floor tiles, rectified edges). Its tool life is 40% longer than SND-G40 (its mid-tier counterpart). The impact resistance (18–22 N) withstands the pressure of grinding hard stones (Mohs 7–8, such as NA black granite and EU basalt), while 90%+ crystal uniformity ensures a consistent Ra ≤1.2μm surface finish on optical glass (e.g., EU camera lenses, NA smartphone screen glass). This meets strict standards like EN 12150 (EU) and ANSI Z87.1 (NA) for optical clarity. Even at 900°C, common in high-speed ceramic grinding, SND-G60 resists softening, ensuring efficiency during prolonged grinding (up to 8 hours) without tool replacement.

FAQ:

Q1: What premium NA/EU applications is SND-G60 best suited for?
A: SND-G60 excels in high-precision, high-durability tasks, including NA residential granite countertop polishing, EU porcelain tile edge grinding, and optical glass manufacturing (e.g., EU camera lenses and NA aerospace optical components). It is also perfect for hard stone engraving, such as NA memorial stone and EU decorative marble.

Q2: Is SND-G60 compatible with electroplated tool systems common in NA/EU?
A: Yes, SND-G60 integrates seamlessly with NA/EU standard electroplated bonding systems (e.g., nickel-electroplated diamond pads, copper-electroplated grinding bits). Its cuboctahedra shape and clean crystal surface ensure strong adhesion to the plating layer, even at high grinding speeds (up to 4,000 RPM).

Q3: When should customers choose SND-G60 over lower grades like SND-G40?
A: SND-G60 is the premium choice for high-end applications requiring high durability and precision. It offers 40% longer tool life than SND-G40 for hard materials like granite and optical glass, with a finer surface finish (Ra ≤1.2μm). SND-G60 is best for luxury kitchen countertops, precision optics, and hard stone grinding, while SND-G40 is more suitable for medium-load tasks like ceramic polishing.
