Path A — Drawing
Use a legally usable controlled drawing with revision, critical dimensions, material and acceptance requirements.
Technical qualification
Drawing, Sample and Measurement-Based Refiner Segment Qualification
Different projects start with different evidence. Every path ends with a controlled definition, first-article verification and application-specific acceptance.
Four qualification routes
Path B — Sample
Measure a representative sample, while recognizing that worn surfaces may not preserve original pattern geometry.
Path C — Customer specification
Use buyer-controlled non-confidential dimensional and material requirements.
Path D — Machine + verification
Use machine identification only as a starting point, followed by controlled measurement of the actual interface.
Qualification workflow
01
Rights check
Confirm the buyer can legally use the supplied drawing, sample or specification.
02
Definition
Freeze mounting geometry, set arrangement, material and relevant pattern information.
03
Engineering review
Clarify tolerances, inspection, tooling/pattern needs and acceptance criteria.
04
First article
Inspect the first article against the approved definition.
05
Controlled trial
The plant or qualified service owner controls installation, startup and process acceptance.
What is not enough
Maker only, model only, approximate diameter, a generic product photo or a supplier compatibility list should not be treated as production-release evidence.
Public intake vs private qualification
Public form can ask
- Application and component type
- Whether drawing/sample/dimensions are available
- Inspection needs
- Whether OEM approval is mandatory
Private review can include
- Specific maker/model
- Detailed dimensions and revision
- Exact pattern information
- Machine and process context
Choose the right starting route
You do not need to publish confidential technical data to begin a preliminary review.
