Responsibility boundary
Refiner Segment Supply vs Machine and Process Responsibility
A custom segment project can define and inspect the component. The plant still controls installation, machine condition, startup and the refining process.
Responsibility matrix
| Sourcing / manufacturing route | Manufacture against the approved definition; agreed material, dimensions, pattern execution, inspection and traceability |
|---|---|
| Buyer / engineering | Legal right to input data, specification approval, acceptance criteria and final technical authorization |
| Maintenance / installer | Holder condition, fasteners, installation, assembly checks, clearance/runout and startup safety |
| Process owner | Gap, steam, feed, motor load, throughput, fiber quality and final board-performance acceptance |
No component-only guarantee can replace plant qualification
Final compatibility, vibration behavior, refining performance and board quality depend on the machine condition, assembly and operating process as well as the segment itself.
Keep the acceptance plan explicit
Part acceptance
- Material / hardness evidence
- Critical dimensions
- Marking / traceability
- First-article conformity
Application acceptance
- Installation condition
- Runout / vibration checks
- Controlled startup
- Process and product trial
Define both sides before ordering
A clear responsibility split reduces ambiguity during first-article and production trials.
