The historical page looks at diamond tools along two different axes: bond terminology and use or structure terminology. Keeping those axes separate makes the old taxonomy easier to read without turning it into an exhaustive standard, a current Huada catalog or a compatibility guide.
Axis one: bond terminology
The frozen source names resin bond, metal bond and ceramic bond. Within its discussion of metal bonding, it also names sintering, electroplating and brazing. These terms are preserved as the archive presents them, without a claim that the count is complete or that every term describes a current product.
Resin bond
An archived category name only; no composition, strength, application limit or product identity is supplied.
Metal bond
A historical heading associated with sintering, electroplating and brazing terms, but no process specification or current mapping.
Ceramic bond
An archived category name with no universal suitability or exclusion supported by the evidence.
Why the two axes should not be collapsed
Bond language addresses one kind of classification, while use and structure names address another. The archive does not say that one axis determines the other. A sawing, drilling or grinding label therefore cannot be used to infer a bond, and a bond label cannot be used to infer a compatible material or task.
Axis two: use and structure families
The archive provides examples under grinding, sawing, drilling and other-tool groupings. Its examples include grinding wheels and related grinding forms; circular, row, rope, barrel, band, chain and wire saw terms; several kinds of drilling bits; and other finishing, cutting and forming tools. The list is retained as historical vocabulary, not promoted as complete.
Universal exclusions removed from the map
The old page included a broad statement about resin and ceramic matrices being unsuitable for sawing, drilling or dressing tools. The frozen audit rejects that universal exclusion because no technical standard or model-bound evidence supports it. This candidate also makes no claim that every listed family is offered by Huada today.
- Not a standard
- The categories are archived organizing views, not a current normative system.
- Not a catalog
- Names in the source do not establish current product ownership or availability.
- Not a selection chart
- No bond-to-material, structure-to-task or model-to-outcome relationship is proven.
