Direct answer: an RR metal deburring machine uses two sanding-belt deburring stations in sequence. The first station performs the main burr-removal and surface-grinding work; the second provides an independently adjustable follow-up pass for a more controlled and consistent result.
This customer-factory video shows a Qintellim RR Series machine processing sheet-metal parts in an actual production environment. Instead of presenting only the machine exterior, the footage follows the workpiece through both R stations so buyers can see how a dual-station sanding-belt process works in practice.

In Qintellim machine naming, R means a sanding-belt deburring station. The sanding belt is the working consumable. In an RR configuration, two R stations are arranged in sequence, but they do not need to run with identical settings.
Carries out the primary deburring or grinding pass. Its sanding-belt specification, contact pressure and feed settings are selected according to the incoming burr condition and material.
Performs a follow-up pass that can use a different abrasive grade or operating setting. It can reduce remaining burrs, refine the scratch pattern or stabilize the final surface condition.
A second R station is not simply a duplicate. Separating the process into two controllable passes can be useful when one aggressive pass would remove the burr but leave an unnecessarily coarse surface, or when production requires more process margin than a single sanding belt can provide.
The footage provides visible process evidence: parts enter on the conveyor, pass below the first sanding-belt station, continue through the second sanding-belt station and exit for inspection. It also shows that the second operation is an R station with a sanding-belt structure—not an edge-rounding or brushing station.
Actual results depend on the workpiece material, thickness, cutting process, burr height, part geometry, abrasive selection, conveyor speed and pressure settings. Qintellim therefore recommends sample testing before the final machine configuration and process parameters are confirmed.
RR is a practical choice when the main requirement is two-stage sanding-belt deburring or grinding. If the target also includes edge rounding or a controlled brushed surface, another function combination may be more suitable.
| Series | Included Process Functions | Typical Selection Logic |
|---|---|---|
| RR | Two sanding-belt deburring stations | Two-stage deburring or grinding without a dedicated edge-rounding or brushing station |
| RRS | Two R stations plus S edge rounding | Two-stage deburring followed by controlled edge rounding |
| RRW | Two R stations plus W brushing/polishing | Two-stage deburring followed by a brushed or polished surface treatment |
Important: the series letters identify included process functions. The final station arrangement, abrasive specification and machine platform must still be verified against the workpiece and production target.
For a qualified recommendation, provide the material grade, minimum and maximum part dimensions, thickness range, cutting process, burr photos, required surface condition, pieces per shift and workshop power conditions. Sample parts or clear drawings help Qintellim engineering confirm whether RR, RRS, RRW or another configuration is the better fit.
Review the representative machine configuration, working width and application information, then send your workpiece details for engineering confirmation.
