Slitting Precision RFQ Acceptance Clause
A slitting precision RFQ acceptance clause for strip width, tolerance band, material, burr, camber, measurement method, FAT/SAT samples, corrective action, and model routing.
A slitting precision requirement belongs in the RFQ and technical attachment as a testable acceptance clause. The clause should define target strip widths, tolerance band, material, thickness, burr, camber, coil-build requirement, measurement tool, sample count, FAT/SAT condition, corrective-action rule, and the model path being evaluated.
This page is the RFQ acceptance clause page in the MaxDo topic network. For the measurement workflow, use the slitting width tolerance measurement protocol. For the technology evidence behind tight tolerance, use the high-precision slitting evidence checklist. This page focuses only on contract-ready wording and acceptance fields.
Write the Tolerance Clause Before Comparing Suppliers
A useful RFQ clause does not say only high precision required. It states what width must be produced, what deviation is allowed, which material is tested, how the result is measured, and what happens if the result drifts. This keeps procurement, engineering, supplier sales, and the receiving plant aligned around the same pass/fail language.
| Clause field | Required wording | Why it matters |
|---|---|---|
| Strip program | Incoming coil width, finished strip widths, strip count, trim allowance | Prevents a generic tolerance from replacing the real recipe |
| Tolerance band | Allowed deviation for each critical strip width | Makes the commercial requirement measurable |
| Material condition | Grade, thickness, strength, coating, surface sensitivity | Precision changes with material behavior |
| Acceptance method | Tool, sample count, sample location, FAT/SAT condition | Prevents disputes after the line is built |
Include Burr, Camber, and Recoiling in the Same Clause
Width tolerance should not stand alone. A strip can be within width and still fail because burr, camber, edge wave, surface marking, loose recoiling, or telescoping blocks downstream use. The RFQ should state which related quality fields must be checked with the same samples.
For defect diagnosis, use the slitting deformation control checklist. For knife-specific setup language, use the slitting line blade setup guide.
Tie the Clause to Material and Gauge Conversion
The clause should identify the material family before it asks for a tolerance number. Stainless, aluminum, mild steel, coated steel, and higher-strength grades can require different clearance, blade material, tension behavior, and speed assumptions. Use the MD series material compatibility checklist to frame the material boundary.
If the buyer’s requirement uses gauge language, convert the gauge into real thickness before the RFQ is issued. Use the gauge thickness chart so the supplier is quoting against millimeters or inches, not a regional shorthand.
Define FAT and SAT Samples in Advance
FAT and SAT should use the same acceptance language. FAT proves the line before shipment with the agreed test material or documented equivalent. SAT repeats the same checks on site with the buyer’s utilities, operators, handling route, and real operating constraints. If the sampling plan changes between FAT and SAT, the clause is too weak.
- Define startup, early-run, mid-coil, and end-coil samples.
- Measure critical strips across the slit program, not only the easiest strip.
- Record width, burr, camber, edge condition, coil build, speed, and operator.
- Attach deviations, correction owner, retest method, and final sign-off.
Add a Corrective-Action Rule
A clause should explain what happens when samples do not pass. The first action should not be random adjustment. The corrective path should review measuring-tool calibration, spacer stack, blade clearance, blade condition, arbor alignment, strip guidance, tension setting, separator pressure, recoiler behavior, and line speed in a documented order.
If the repeated issue points to controls rather than one setup mistake, connect the clause to the slitting line control system upgrade roadmap. If setup repetition is the issue, use the slitting line setup time reduction checklist.
Sample RFQ Clause Structure
The buyer may adapt the following structure for a technical attachment: The slitting line shall produce the agreed strip program from the defined material and coil envelope. Width tolerance, burr, camber, and recoiling quality shall be verified using the agreed tool, sample plan, and FAT/SAT material condition. Any deviation shall be recorded, corrected, retested, and signed off before acceptance.
| Attachment section | Minimum content |
|---|---|
| Material and coil envelope | Grade, thickness, strength, coating, coil width, coil weight, ID/OD |
| Strip program | Finished widths, strip count, trim, tolerance band, downstream process |
| Quality fields | Width, burr, camber, surface, edge condition, coil build |
| Acceptance record | Sample count, tool, location, FAT/SAT condition, deviation closeout |
Route the Clause to the Right Slitting Model
After the clause is clear, route the project through the metal slitting machine category. Compact or narrow programs may begin with MA-850. Mid-width programs can compare MA-1350. Wider or heavier programs should evaluate MD-1650 and MD-2200 against the actual strip program.
If the precision clause belongs inside a wider project package, combine it with the industrial slitting line project scope checklist. To ask MaxDo to review a tolerance clause, send the material range, coil envelope, strip program, tolerance band, sample plan, FAT/SAT method, and model boundary through the contact form.
