05 / TECHNICAL SELECTION GUIDE
How to Select Crushed RVD Diamond Grit
Begin with the workpiece and the abrasive tool. Evaluate the particle characteristics together with mesh size, bond formulation and actual grinding conditions.
01
Identify the Workpiece
Specify marble, granite, quartzite, ceramic, glass, cemented carbide or another material. Include hardness, brittleness and surface requirements where available.
02
Define the Grinding Operation
Clarify whether the tool is used for stock removal, edge shaping, grinding, polishing or finishing. Include working pressure and required surface quality.
03
Match Grade, Mesh & Bond
Select a candidate grade and mesh fraction while reviewing resin formulation, abrasive concentration, grain exposure and bonding requirements.
04
Validate in the Finished Tool
Compare cutting action, removal rate, edge quality, surface finish, grinding force, abrasive wear and cost per finished component.
Why Mesh Size Matters
Coarser diamond grit may suit earlier grinding stages and greater material-removal requirements. Finer grit may be suitable for more controlled finishing operations. However, particle size alone does not guarantee a particular surface finish, removal rate or wheel life.
SND-G05: Confirmed available range of 80–500 mesh. Specify the individual mesh fraction and grading standard.
SND-G10 / SND-G15: Request the current grade-specific mesh list and particle-size distribution. Do not assume every grade shares the same size range.
06 / TOOL DESIGN
Bond Compatibility & Abrasive-Tool Development
Diamond abrasive performance depends on crystal properties, grain retention, bonding chemistry and the manufacturing process. Bond compatibility should be evaluated rather than assumed from the RVD designation alone.
Resin Bond
Primary application direction. SND-G crushed RVD grades are primarily positioned for resin-bond grinding, edging and polishing tools. Final suitability depends on the specific grade and resin formulation.
Electroplated Bond
Technical validation required. Grain shape, plating chemistry, nickel-layer retention, abrasive exposure and tool operating conditions must be evaluated before adoption.
Vitrified Bond
Technical validation required. Bond composition, firing temperature, diamond stability and abrasive retention must be reviewed for the intended tool design.
07 / TECHNICAL FAQ
Frequently Asked Questions – Crushed RVD Diamond
Technical questions from abrasive-tool manufacturers comparing crushed diamond grain morphology, grade positions, particle sizes and bond compatibility.
1. What is Crushed RVD Diamond Powder?
Crushed RVD diamond powder is an industrial diamond abrasive characterized by irregular, angular particles and fractured crystal surfaces. It is selected for suitable bonded grinding, edging and polishing tools according to particle size, grain behavior, bond system and workpiece requirements.
2. What does RVD mean in SinoDiam's product range?
SinoDiam uses Crushed RVD to identify its SND-G05, SND-G10 and SND-G15 family of crushed diamond abrasive grades. RVD terminology may differ between suppliers, so customers should compare actual particle morphology, material specifications, mesh grading and application suitability rather than relying on the abbreviation alone.
3. What is the difference between SND-G05, SND-G10 and SND-G15?
SND-G05 is the Economy Green grade, SND-G10 is the Standard Yellow grade and SND-G15 is the Premium Yellow grade. G05 focuses on economy-oriented grinding and edging, G10 on general-purpose stone grinding and polishing, and G15 on evaluating grain integrity under demanding grinding conditions. These are selection positions, not guaranteed strength or tool-life rankings.
4. Is SND-G05 made from synthetic diamond?
Yes. SinoDiam SND-G05 uses synthetic diamond feedstock and is offered in the 80–500 mesh range. Feedstock documentation and individual mesh specifications for SND-G10 and SND-G15 should be confirmed separately.
5. What mesh sizes are available for the SND-G series?
SND-G05 has a confirmed 80–500 mesh offering. The available mesh fractions and grading standards for SND-G10 and SND-G15 should be verified using their individual technical specifications. The same mesh range should not be assumed for every grade.
6. Which bond system is recommended for Crushed RVD Diamond?
Resin-bond grinding, edging and polishing tools are the primary application direction for the SinoDiam SND-G series. Final suitability depends on resin chemistry, particle size, abrasive concentration, tool design and grinding conditions.
7. Can crushed RVD diamond be used in electroplated or vitrified tools?
These applications require separate technical validation. Electroplated tools depend on plating chemistry, grain exposure and retention. Vitrified tools require evaluation of bond chemistry, firing conditions and diamond stability. Universal compatibility cannot be assumed.
8. How is Crushed RVD different from Resin Bond RVG diamond?
SinoDiam's Crushed RVD series emphasizes angular crushed-grain characteristics and economy-to-premium grade positioning. The separate SND-R resin-bond RVG family is organized primarily by relative friability and abrasive self-sharpening behavior. Their applications can overlap, but grade selection requires technical comparison.
9. Is Premium SND-G15 always better than SND-G10?
No. A premium-positioned grade is not necessarily the best abrasive for every grinding wheel. Grain strength, controlled fracture, bond retention, material removal, wheel wear and workpiece requirements must be evaluated together. A measured toughness or tool-life advantage requires comparable test data.
10. Can SND-G grades replace a competitor's RVD abrasive?
A competing abrasive can be considered for comparative evaluation, but direct equivalence is not guaranteed. Provide its model, material specifications, mesh designation, grading standard, workpiece, tool construction and grinding-performance results to support a suitable trial.
11. What information is needed for an SND-G quotation?
Please provide the target diamond grade, required mesh fraction, grading standard, workpiece material, bond system, abrasive-tool type, grinding operation, trial or order quantity and destination country. Existing abrasive specifications can help SinoDiam review the inquiry.
