Before powder coating, a sheet metal part may need deburring, edge rounding, or both. Deburring removes raised burrs and suitable residue, while edge rounding creates a smoother radius on accessible edges. The required result should come from the part drawing, coating specification and downstream inspection criteria, then be confirmed by sample testing.
Edge rounding can create a more consistent edge geometry for handling and coating preparation. The resulting edge condition should be evaluated together with cleaning, chemical pretreatment, grounding, coating application, curing and final coating inspection.
Laser-cut, punched, stamped and sheared parts can leave different edge conditions. One part may have a raised burr. Another may be burr-free but still have a sharp edge. A third may have heavy slag or a surface condition that requires a different first process.
Sharp or inconsistent edges can be more difficult to coat uniformly than broad flat surfaces. The practical goal of edge preparation is therefore not to claim a universal coating result, but to present the coating process with the edge condition required by the buyer's drawing or quality specification.
| Incoming Condition | Process to Evaluate | Qintellim Function | What Must Be Confirmed |
|---|---|---|---|
| Raised burrs or suitable surface residue | Sanding-belt deburring | R station with sanding belt consumables | Burr direction, height, material, surface target and belt sequence |
| Sharp edges without significant primary burr removal | Radius edge rounding | S station with rotary roller brush tooling | Accessible contours, target edge result, brush specification and part holding |
| Burrs plus a rounded-edge requirement | Deburring followed by edge rounding | R + S process route | Whether RS, RRS, RSR or another approved sequence produces the required sample result |
| Heavy slag from plasma or flame cutting | Heavy-slag removal before finer processing | C function, followed by R or S when required | Slag size, attachment, plate thickness, material and production target |
On Qintellim machines, S identifies an edge-rounding station. The station uses rotary roller brush tooling to create a smoother radius on suitable external contours and accessible holes, slots or internal features. It is an edge-rounding process, not a true chamfering process that cuts a defined bevel.
An S station should not automatically be used as a substitute for significant primary burr removal. When the incoming part has raised burrs and the final part also needs a rounded edge, an RS-Series route combines R sanding-belt deburring with S rotary roller brush edge rounding.
Evaluate an S-Series sheet metal edge rounding machine when suitable parts already have a controlled incoming surface and the primary requirement is a smoother radius on accessible edges.
Evaluate an RS-Series deburring and edge rounding machine when the part needs sanding-belt burr removal before or around the rotary roller brush stage.

Qintellim S- and RS-Series projects can be evaluated in 450, 630, 800, 1000, 1300 or 1600 mm working widths. Every width is project-based and should be selected from the maximum part dimension across the conveyor, part orientation, edge access and required throughput.
Openings, contact area, flatness, part rigidity and process load must be reviewed before the conveyor platform is approved.
This Qintellim S-Series demonstration shows a representative single S-station process, including setup, loading, rotary roller brush contact and conveyor output. It demonstrates the process route only; it does not establish a universal edge radius or coating result.

A useful sample test should represent actual production, not only a clean flat coupon. Send the following information with the parts:
After mechanical edge preparation, the buyer's coating team can evaluate the complete route, including cleaning, pretreatment, grounding, coating coverage, appearance and curing, against the project specification. Qintellim sample testing records the mechanical edge result for this downstream review.
No. The required edge condition depends on the drawing, coating specification, part use and inspection criteria. Some parts only need burr removal, while others require a defined rounded-edge result.
An S station is designed for edge rounding with rotary roller brush tooling. Significant primary burr removal normally requires an R sanding-belt station, and heavy slag requires a C function before finer processing.
There is no single Qintellim series-wide radius value. Use the part drawing or coating requirement, then confirm the achievable result from the material, geometry, brush tooling, process settings and sample test.
It can treat suitable accessible features when the brush can reach the edge and the workpiece remains stable on the conveyor. Drawings and representative samples are required for difficult geometry.
Send Qintellim your workpiece drawings, burr photos, material, dimensions, target edge result and coating-process requirements. Engineering can evaluate whether the project needs S edge rounding, R deburring plus S edge rounding, or another confirmed process route.
