MD-850 Compact Slitting Acceptance Checklist
A narrow compact slitting acceptance checklist for material range, strip width, blade setup, burr, width tolerance, setup time, coil handling, FAT/SAT records, and model routing.
An MD-850 compact slitting project should be accepted by its strip program, material range, blade setup, burr limit, width tolerance, recoiling behavior, setup record, FAT/SAT evidence, and model boundary. A compact 850-class line can be a strong fit, but only when the buyer proves that the real coil window and finished strip program belong in this class.
This page is the MD-850 compact slitting acceptance checklist in the MaxDo topic network. For the 850-class setup-fit intake, use the MD-850 thin-gauge slitting setup checklist. For compact engineering tradeoffs, use inside the MD-850. For HVAC and appliance application fit, use the MD-850 HVAC and appliance strip program map. This page is a narrow support page for compact slitting acceptance evidence. It owns only the acceptance layer: material range, strip width, blade setup, burr, width tolerance, setup time, coil handling, FAT/SAT records, and model routing. It is not the MA-850 product page, not the compact engineering tradeoff page, and not the MA/MD model fit matrix.
Freeze the 850-Class Application Boundary
The acceptance record should define why the project belongs in an 850-class compact slitting platform. Record incoming coil width, material grade, thickness range, yield strength, coating, surface sensitivity, finished strip widths, strip count, trim allowance, finished coil ID and OD, and downstream process. If future jobs may exceed this boundary, review the next model before signing off.
| Acceptance field | What to record | Risk if missing |
|---|---|---|
| Material window | Grade, thickness, strength, coating, surface sensitivity | Wrong blade setup, marking, or overload risk |
| Strip program | Incoming width, strip widths, strip count, trim, tolerance | Quote fits a sample, not the real production mix |
| Recoiling output | Finished coil ID/OD, separator method, coil tightness, unloading | Accepted strip width but rejected coil package |
| Expansion boundary | Future width, thickness, material, and volume expectations | Compact line becomes undersized too early |
Accept Width, Burr, and Camber Together
MD-850 acceptance should not rely on one width number. Record width tolerance, burr limit, camber limit, edge condition, measuring tool, sample count, sampling location, and action rule when drift appears. For the measurement method, use the slitting width tolerance measurement protocol.
Gauge language should also be converted before acceptance. Use the gauge thickness RFQ helper to turn commercial gauge references into thickness, material, and tolerance records.
Tie Blade Setup to the Test Material
Blade setup should be accepted against the material actually used in the project. Clearance, overlap, blade condition, spacer stack, arbor condition, separator pressure, and line speed can change between galvanized steel, stainless, aluminum, coated steel, and pre-painted coils. For detailed knife preparation, use the slitting line blade setup guide.
If the plant changes jobs frequently, connect blade setup to the slitting line setup time reduction checklist. Acceptance should include not only first-good-strip quality, but also how repeatable the setup is across operators and repeat jobs.
Inspect Recoiling and Coil Handling as Output Quality
A compact slitting line can produce correct strips and still fail if finished coils are loose, telescoped, scratched, difficult to unload, or unstable for downstream use. Record separator setup, recoiler tension, finished coil build, surface condition, unloading method, packing method, and handling route. If deformation or coil shape is the issue, use the slitting deformation control checklist.
For material and strength boundaries across the MD and MA range, use the MD series material compatibility checklist. If the project is mainly about yield loss, connect the acceptance record to the slitting scrap process loss map.
Build the MD-850 FAT and SAT Record
FAT should prove the accepted strip program before shipment. SAT should repeat the same checks on site with the buyer’s utilities, operators, handling route, and material. Record deviations, correction owner, retest method, training, spare parts, final settings, and sign-off. A compact line acceptance is not complete until quality and handling are both proven.
- Freeze material grade, thickness, strength, coating, coil width, and finished strip widths.
- Measure width, burr, camber, edge quality, surface condition, and coil build on repeated samples.
- Attach blade setup, spacer stack, separator method, recoiling setting, and first-piece release records.
- Record setup time, setup scrap, correction loops, operator training, deviation list, and final sign-off.
Route the Project to the Correct Model Path
After the acceptance boundary is clear, compare the MA-850 metal slitting machine and the metal slitting machine category. If the project exceeds the compact boundary, review MA-1350, MD-1650, and MD-2200 against the actual strip program.
For broader model selection, use the MA and MD slitting machine model fit matrix. To request an MD-850 acceptance review, send MaxDo the material range, coil width, strip program, burr and width tolerance targets, blade setup method, recoiling requirement, FAT/SAT plan, and future expansion boundary through the contact form.
