Product Overview
SinoDiam SND210 Oil-Soluble Diamond Compound is an industrial diamond abrasive paste positioned for precision lapping, mold and die polishing, carbide-component finishing and selected toolroom applications.
The compound combines fine synthetic diamond abrasive particles with an oil-based carrier system. The carrier provides a medium for distributing the abrasive across the polishing interface. Effective performance depends on the abrasive size and morphology, diamond concentration, carrier formulation, polishing medium and workpiece characteristics.
SND210 is particularly relevant to manufacturers evaluating diamond paste for cemented carbide drawing dies, selected mold inserts, precision tools and suitable hard-material surfaces. The final abrasive specification should be matched to the required material removal, surface quality and polishing method.
For oil-compatible finishing operations, the carrier may help distribute the compound and maintain abrasive contact during use. However, lubrication behavior, working time, viscosity and cleaning requirements are formulation-dependent and should be verified for the actual material supplied.
Diamond is not automatically the preferred abrasive for every metal. For hardened ferrous workpieces, CBN-based polishing compounds may be considered depending on processing temperature, contact conditions and tool requirements. Any CBN formulation should be confirmed as a separate available specification rather than assumed to be included in standard SND210.
The historical SinoDiam catalogue references micron sizes from 0.25 to 50 ฮผm, multiple concentration levels and different packaging options. These remain catalogue references until the current available grades, actual particle-size distributions, diamond content and package configurations are confirmed.
For application selection or quotation, please provide the workpiece material, polishing method, requested micron size, desired surface condition, abrasive concentration requirements, estimated quantity and destination country.
Technical Specifications
Technical values are not automatically established by the model name. Current particle sizes, diamond loading, carrier properties, packaging and shelf-life conditions should be confirmed using the actual product specification. The historical 0.25โ50 ฮผm range is not a guarantee that every individual fraction is available.
Oil-Based Carrier & Diamond Abrasive Characteristics
A successful polishing compound combines a suitable abrasive with a carrier system compatible with the workpiece, applicator and cleaning process. The diamond particles and the carrier should be evaluated separately.
Abrasive Distribution
The oil-based medium helps place and distribute diamond particles at the polishing interface. Actual uniformity and stability depend on carrier rheology, particle concentration and the working method.
Diamond Micron Size
Particle size influences abrasive contact and processing behavior. PSD, crystal shape and oversize control are relevant for both material removal and sensitive finishing applications.
Polishing Medium
Evaluate SND210 with the selected polishing cloth, felt, lap or tooling medium. Carrier compatibility and abrasive embedding behavior should be checked for the actual process.
Pressure, Speed & Temperature
Finishing results depend on contact pressure, relative motion, workpiece temperature and polishing duration. A compound alone does not establish the correct machine settings.
Oversize & Contamination Control
Unexpected larger particles or foreign debris can affect surface quality. Clean handling and suitable particle-size inspection are important for precision finishing.
Cleaning & Residue
An oil-based compound may require a compatible cleaning procedure. The cleaning agent must be selected around the carrier, workpiece material and downstream inspection requirements.
Why Carrier Selection Matters
Oil-based and water-soluble diamond compounds are different formulation systems. Neither should be considered universally superior. Select the carrier according to lubrication requirements, polishing medium, residue tolerance, workpiece compatibility and available cleaning methods.
Diamond Micron Size Selection for Lapping & Polishing
The abrasive size should be chosen according to the processing stage, workpiece characteristics and desired surface condition. The following size windows are general application examples, not a confirmed list of SND210 stock grades.
Fine Finishing0.25โ3 ฮผm
Consider finer diamond sizes for suitable late-stage polishing or surface refinement. Oversized-particle control, agglomeration and cleanliness may be especially important.
Intermediate Lapping3โ15 ฮผm
Evaluate intermediate fractions for selected lapping and pre-finishing operations requiring a balance between abrasive removal and surface requirements.
Coarser Compound15โ50 ฮผm
Consider coarser micron sizes for earlier finishing stages where more pronounced abrasive contact is acceptable. Verify workpiece damage and the need for subsequent finer stages.
Important Size-Specification Factors
Nominal Size vs. D50
A nominal micron designation does not automatically equal a measured median particle diameter. Request the grading definition and measurement basis.
D10 / D50 / D90
Review the available particle-size distribution when material consistency or surface quality is important. Values should be compared using compatible measurement methods.
Oversized Particles
Fine finishing may require limits beyond ordinary D90 reporting. Isolated oversized particles can matter even when the general distribution appears acceptable.
Polishing Sequence
More than one particle size may be required. Selection of successive stages depends on the starting surface and final inspection target.
The size windows are illustrative and do not guarantee availability, a particular surface finish or fixed removal rates. Ask SinoDiam to confirm current size fractions for the requested compound.
Diamond Concentration, Dispersion & Packaging
Diamond loading and carrier rheology influence how a polishing compound is applied. The correct formulation should be selected through application requirements and suitable process trials rather than concentration level alone.
Light
A possible evaluation direction for selected finishing work requiring a lower abrasive loading. The actual formulation and diamond content must be confirmed.
Medium
Consider as a formulation option when abrasive contact, handling behavior and process efficiency need to be balanced. Confirm availability and actual loading.
Heavy
Higher abrasive loading may be investigated for suitable removal-oriented operations. More diamond does not automatically guarantee faster or better polishing.
What Does Diamond Concentration Mean?
Concentration may be reported as diamond mass fraction, abrasive weight per package, carat content or a manufacturer-defined grade. These reporting methods should not be considered directly equivalent without a clear specification.
Available Packaging & Dispensing
The historical SinoDiam catalogue references multiple tube, syringe and jar quantities. Please confirm the available packaging size, net compound weight, nominal abrasive content and dispensing format before placing an order.
Formulation and Dispersion
Carrier composition, diamond concentration, viscosity and particle dispersion should be qualified for the intended polishing method. The effect on tool handling and finish should be evaluated with the selected workpiece and applicator.
This page does not establish fixed concentration percentages, guaranteed packaging configurations, custom manufacturing availability or a universal shelf life.
Recommended Applications of SND210 Diamond Compound
SND210 is primarily positioned for precision polishing and lapping processes where synthetic diamond paste and an oil-compatible carrier are appropriate. Each application requires matching particle size, abrasive loading and polishing conditions to the workpiece.
Cemented Carbide Drawing Dies
Evaluate diamond compound for lapping and polishing suitable tungsten-carbide drawing die surfaces. Select abrasive size according to initial condition, required geometry and final finish.
Mold Insert Polishing
For selected mold inserts and precision tooling where an oil-based diamond compound is compatible with the workpiece and polishing medium. Ferrous mold steels require appropriate abrasive and process evaluation.
Cold Heading & Forming Dies
Consider for compatible carbide die polishing, refurbishment and controlled surface correction. Material type and polishing conditions should be confirmed before selection.
Precision Toolroom Finishing
Suitable toolroom components may require localized lapping or surface finishing. Evaluate particle size, applicator type and workpiece compatibility for the intended operation.
Technical Ceramic Components
Selected engineering ceramics may be candidates for diamond compound polishing. Surface damage, abrasive loading and processing medium need to be assessed through trials.
Hard-Material Lapping
For compatible hard and brittle components where a diamond abrasive is an appropriate choice. Establish the required grinding or lapping sequence and validate the resulting surface.
Applications are technical evaluation directions. SND210 does not guarantee mirror-quality surfaces, scratch-free polishing or compatibility with every mold alloy, ceramic or machine.
How to Select & Apply an Oil-Soluble Diamond Compound
Use a controlled selection and application procedure to reduce unnecessary abrasive changes and improve the reliability of polishing trials.
Identify the Workpiece
Confirm the material, initial surface condition and whether synthetic diamond is suitable. Evaluate CBN or another abrasive when the workpiece and processing conditions require it.
Select the Abrasive Size
Specify the nominal micron range, grading requirements, surface-quality target and possible processing sequence. Request current size availability.
Match Carrier & Concentration
Confirm oil-carrier compatibility with the workpiece, polishing pad, lubricant or extender, application method and subsequent cleaning process.
Validate the Finished Surface
Use representative samples to evaluate removal behavior, roughness, visible scratches, surface damage and process repeatability before establishing a production process.
Handling & Cleaning Considerations
Prevent contamination between abrasive sizes and avoid mixing incompatible carriers or polishing products. Use cleaning methods approved for the workpiece and compound formulation. Storage, personal protective equipment and shelf-life requirements should follow the current product label and applicable Safety Data Sheet.
Oil-Soluble vs. Water-Soluble Diamond Compound
Carrier selection should be based on the polishing workflow rather than an assumption that one carrier always gives better results. The two SinoDiam compound families are intended for different application requirements.
| Selection Factor | Oil-Soluble Compound | Water-Soluble Compound | ||
|---|---|---|---|---|
| Carrier System | Oil-based / oil-compatible formulation | Water-compatible formulation | ||
| Typical Evaluation | Mold, die and toolroom polishing processes | Specimen preparation and processes requiring different cleaning conditions | ||
| Lubrication | Verify with the actual oil carrier | Verify with the actual water-compatible carrier | ||
| Cleaning | Requires suitable oil-compound cleanup | Evaluate appropriate water-based cleanup | ||
| Residue Control | Confirm compatibility with inspection and downstream processing | Confirm actual residue and substrate compatibility | ||
| Abrasive Selection | Specify grade, micron size and concentration | Specify grade, micron size and concentration | ||
| Performance | Requires application testing | Requires application testing | ||
The current SinoDiam water-soluble product documentation uses inconsistent model numbers. This comparison intentionally identifies the water-soluble product by its carrier type until its official model code is confirmed.
