Product Overview

SND-R10 High-Friability Semi-Blocky RVG Diamond Powder is a synthetic diamond abrasive developed for general-purpose resin-bond grinding wheels. It combines a semi-blocky crystal shape with increased friability to support a balance between abrasive cutting action, grain retention and grinding-wheel economy.

Positioned below the ultra-high-friability SND-R05 grade, SND-R10 is intended for grinding-wheel manufacturers seeking controlled abrasive breakdown without relying on the most fragile diamond grade in the series.

The semi-blocky crystal morphology provides a practical balance between crystal integrity and the ability to generate fresh cutting edges during grinding. This behavior can support free-cutting action, controlled self-sharpening and abrasive wheel performance when matched with a suitable bond formulation.

SND-R10 is recommended for evaluation in resin-bond tools processing cemented tungsten carbide, cermets, technical ceramics, glass and selected hard, brittle non-ferrous materials.

As an economy-oriented grade, its value should be assessed through overall grinding cost, cutting performance, wheel wear, dressing requirements and finished-part quality rather than abrasive purchase price alone.

Crystal Characteristics & Grinding Behavior

High Friability

SND-R10 is positioned as a high-friability grade intended to fracture more readily than the tougher grades within the SND-R series. The actual fracture response depends on grain size, applied grinding force and test conditions.

Semi-Blocky Crystal Morphology

Its semi-blocky grain shape is relevant to the balance between structural integrity, abrasive contact and controlled cutting-edge renewal. Crystal morphology should be evaluated together with the resin-bond formulation.

Controlled Self-Sharpening

Under suitable grinding conditions, localized abrasive microfracturing can create new cutting edges and reduce the tendency toward grain dulling or wheel glazing.

Cost-Effective Grinding Potential

SND-R10 is intended for wheel manufacturers evaluating the relationship between abrasive cost, cutting efficiency, wheel consumption and total grinding cost per workpiece.

Recommended Applications

The following applications reflect the typical use of high-friability, semi-blocky resin-bond diamond abrasives. Final suitability should be verified for the specific SND-R10 grade and grinding-wheel system.

Cemented Carbide Grinding

For evaluation in resin-bond diamond wheels used to grind tungsten carbide cutting tools, carbide inserts and precision carbide components. Select grain size and bond hardness according to the carbide composition and removal requirements.

Cermet Grinding

Semi-blocky high-friability diamond grains can be considered for controlled grinding of selected cermet workpieces, where cutting-edge renewal, workpiece integrity and wheel wear must be balanced.

Technical Ceramic Grinding

Suitable for grinding trials involving selected technical ceramics. Important process factors include grinding forces, material removal rate, brittle fracture, surface integrity and wheel life.

Glass Edge Grinding

For evaluation in resin-bond tools used for glass edge processing, shaping and precision grinding. The abrasive size, wheel design and operating conditions determine the achievable edge quality.

Hard & Brittle Non-Ferrous Materials

Potential applications include selected hard, brittle non-ferrous and non-metallic components where diamond abrasives are appropriate. Workpiece compatibility must be confirmed before production use.

General-Purpose Resin Bond Wheel Manufacturing

Designed for abrasive-tool manufacturers seeking a cost-conscious diamond grade for precision grinding wheels, tool sharpening and selected finishing operations involving diamond-compatible workpieces.

Material selection note: Diamond abrasives are generally used for carbide, ceramics, glass and non-ferrous materials. For hardened steel and other ferrous materials, CBN is normally the preferred superabrasive unless a specific process has been validated.

Mesh Size Selection & Grinding Requirements

The choice of diamond grit size influences material removal, cutting-point density, workpiece finish and abrasive-wheel behavior. SND-R10 should be selected according to the target operation rather than mesh size alone.

Coarser Grit
For evaluating higher removal-rate grinding operations where acceptable surface integrity and bond retention can be maintained.
Intermediate Grit
For applications balancing stock removal, finishing requirements and grinding-wheel wear.
Finer Grit
For precision grinding and finishing where surface quality, edge integrity and controlled cutting behavior are priorities.

The existing product catalogue states a nominal range of 60/70–325/400 mesh. Confirm the individual size, grading standard, particle-size distribution and availability with SinoDiam. A particular surface roughness cannot be guaranteed by grit size alone.

Resin Bond Compatibility & Wheel Design

SND-R10 is primarily positioned for resin-bond grinding-wheel manufacturing. Phenolic and polyimide formulations may be evaluated according to wheel design, manufacturing conditions and intended grinding application.

The combination of crystal friability and semi-blocky morphology should be assessed with the selected bond hardness, diamond concentration and abrasive retention requirements. Excessively weak grain retention or uncontrolled grain fracture may increase wheel wear, even when the abrasive demonstrates effective self-sharpening behavior.

Important Wheel Design Considerations

  • Resin chemistry, bond hardness and manufacturing conditions.
  • Diamond concentration and grit-size distribution.
  • Crystal retention, cutting-edge renewal and abrasive wear.
  • Wet or dry grinding conditions, wheel speed and grinding pressure.
  • Wheel profile, dressing conditions and dimensional accuracy.
  • Material removal rate, G-Ratio and cost per finished component.

Vitrified-bond applications require separate evaluation of firing conditions, bond chemistry and abrasive stability. Suitability should not be assumed for every vitrified-bond formulation.

Why Select SND-R10 for General-Purpose Grinding?

Economy-Oriented Grade Selection

SND-R10 provides an option for manufacturers comparing abrasive performance and material cost in general-purpose resin-bond grinding-wheel formulations.

Balance of Fracture & Retention

Its high-friability, semi-blocky positioning is intended to balance cutting-edge generation with grain retention under suitable grinding conditions.

Application Flexibility

Relevant evaluation targets include carbide, cermets, technical ceramics, glass and selected hard-and-brittle materials rather than a single narrowly defined workpiece.

Practical Performance Evaluation

Compare candidate wheel formulations using grinding force, surface finish, wheel wear, dressing interval and total cost per part instead of relying only on descriptive grade labels.

SinoDiam SND-R Series Grade Selection

Different resin-bond diamond grades may be selected to match the required balance between abrasive fracture, self-sharpening, grain strength and wheel life. The relative classifications below are intended as a series-selection guide.

SinoDiam’s relative grade positioning is not a claim of equivalence to other manufacturers’ products. Individual technical data and application testing should be used for final grade comparison.

Frequently Asked Questions
