Selection guides
Choose the right abrasive family, grit band and grading standard for each workpiece.
Blog & insights
Technical guidance for abrasive buyers
We publish the questions our technical team answers most often: how to select a material, how to read a specification, and what to check before an abrasive enters a precision polishing line.
Editorial focus
A resource center, not a newsfeed
We keep articles practical and specification-first, so they remain useful long after publication.
Process notes
Practical lapping and polishing guidance for semiconductors, crystals, glass and ceramics.
Quality control
Chemistry, particle size distribution, batch traceability and inspection checkpoints.
Buying from China
Specification language, sample evaluation, packaging, logistics and export documentation.
Starting articles
Three articles to begin with
How to choose between WFA, GC, PWA and BFA
A practical framework for matching material, hardness, grain shape and grit band to your workpiece.
- Start from the workpiece
- Match material to process
- Specify grit and standard
- Run a controlled comparison
Why tabular alumina behaves differently in wafer lapping
The hexagonal platelet is not marketing language: it changes how pressure transfers and how the grain moves across a wafer.
- Equiaxed grain versus platelet
- Why scratches fall
- Where the numbers come from
- What to ask a supplier
A six-point specification checklist for abrasive imports
A clear technical specification prevents most quotation delays, sample mismatches and incoming-inspection disputes.
- Material and grade
- Chemistry limits
- Particle distribution
- Sampling and acceptance
- Packaging and labelling
- Traceability and documents
Framework
How each article will be written
Every article follows the same structure so buyers can compare materials and process decisions quickly.
Define the problem
Start with the process limitation: scratch, removal rate, consistency, purity or cost.
Explain the material variable
Connect grain shape, hardness, chemistry, grit distribution or grading standard to that limitation.
Give a practical next step
End with what to specify, what to test and what evidence to request from the supplier.
Next step
Send a technical question
If a topic here does not answer your process question, send the workpiece material, target finish and current abrasive. We will suggest a grade and grit band.
