Moving-tool edge sanding · Applied by Titan
A programmable edge-sanding platform that clamps large doors, panels, window parts and stair components in place while a frequency-controlled double-brush carriage moves along the edge. Three working areas, opposing tool rotation, 200 mm spindle flexibility, jump control, oscillation and productive return strategies turn difficult profiled edges into a controlled stationary-workpiece process.
The actual production problem
ROBA Profi Edge holds the workpiece under a pneumatic pressure bar and moves a programmable double-brush carriage instead—separating edge quality from the operator’s ability to guide a heavy panel past a fixed tool.
Long cabinet fronts, doors, stair components, window parts and panels become difficult to guide consistently when the operator must move the entire workpiece along a sanding tool.
ROBA Profi Edge clamps the workpiece under a pneumatic pressure bar while the double-brush carriage travels through the encapsulated machine.
A single rotation direction can favour one fibre orientation and leave another standing. Solid-wood end grain, MDF fibres and profiled transitions do not present one uniform sanding direction.
The extra-large double-brush tools rotate frequency-controlled clockwise and counterclockwise so the released process can approach fibres from both directions.
A process can look acceptable along the long run and still soften or over-round the entry and exit corners. More passes usually make that defect worse.
Jump control defines where the tool engages and disengages, while the programmed processing speed governs travel through the actual sanding zone.
Straight edges, fine profiles, chamfers and coating stages need different brush geometry and support. A fixed 200 mm cylindrical tool cannot be ideal for every family.
Each 200 mm spindle can carry one full-height cylindrical brush, two stacked 100 mm tools, or application-selected chamfered tooling that the program positions pneumatically.
Application fit
The strongest fit combines large or awkward parts, profiled edge families, demanding corners and enough repeat work to benefit from programmed tool travel.
The stationary-part cycle supports cabinet doors and panels whose four edges are processed by rotating the part 90 degrees between released passes.
Pneumatic clamping and a moving sanding carriage are well suited to larger workpieces that are awkward to pass manually across a fixed edge tool.
Opposing brush rotation helps address changing fibre direction around window, stair and joinery components. The actual tool and motion program are proven on the species and profile.
For MDF and coated edges, tool geometry, grit, support and jump points are selected to remove fibres or denib the film without changing profile definition.
Finished edge first
Configure from the accepted coated edge backward through substrate, profile, corner, clamp surface, spindle stack, tool direction, jump points and motion program.
Use matched raw, accepted and rejected parts. Define the fibre, scratch, profile or coating defect and the maximum permissible change at every corner and high point.
Work area, clamp, tool stack, double-brush rotation, carriage motion, oscillation, extraction and inspection are engineered as one cell.
Prove the longest, most profiled and most finish-sensitive edge.
Record MDF grade, species, edge construction, primer, lacquer, cure and the amount of material or coating the process may safely remove.
Define length, height, profile depth, corners, end grain, inside details and the surface available for the pneumatic pressure bar.
Use one 200 mm cylindrical tool, two 100 mm tools with distinct grits, or chamfered tools where profile access requires an inclined sanding field.
Define high-speed approach, programmed sanding feed, travel direction, jump points, oscillation and whether the return is rapid, productive or uses another tool.
Inspect fibre removal, scratch, profile, corners and coating breakthrough after all rotations, then verify the result through the normal next finish stage.
Machine architecture
The encapsulated Profi Edge combines a stationary workpiece, travelling double brush, opposing tool rotation, flexible spindles and programmable motion states.
A pneumatic pressure bar holds the workpiece while the sanding carriage moves. Large parts remain supported rather than being manually guided along the tool.
Clamping surface, part construction and allowed pressure are confirmed on the real family.
The MB double-brush aggregate is mounted on a travelling support inside the encapsulated machine. The carriage approaches in high-speed mode and crosses the sanding region at programmed processing speed.
Extra-large sanding tools rotate frequency-controlled clockwise and counterclockwise. This provides two directional approaches for solid-wood end grain, MDF fibres and changing profiles.
Jump control manages engagement around part ends to reduce over-rounding. Aggregate oscillation distributes wear across the abrasives and supports a consistent result.
Each 200 mm spindle can accept one 200 mm cylindrical brush or two 100 mm stacked tools that may use different grits. Chamfered sanding areas support more complicated contours.
The sanding program stores which tool is required for a family. Pneumatic positioning selects the intended tool so different outbound and return passes can perform different jobs.
Technical specifications
ROBA Profi Edge combines three working areas with programmable tooling and motion architecture. Final motor, utility, footprint and output requirements are confirmed for the selected cell.
Throughput strategy
Loading, clamping, high-speed approach, productive travel, return strategy, tool changes, rotation, inspection and finish yield determine sustained output.
Time representative families from staging through every edge, rotation and final acceptance.
Grouped parts count only when loading, clamping and finish remain repeatable.
Recipe engineering
Each program binds part, clamp, tool stack, rotation, travel direction, feed, jump points and finish acceptance.
Bind material, dimensions, profile, corners, coating stage and clamping face to one controlled program.
Record full-height, stacked or chamfered tool geometry, grit, support, position and the defect each tool must remove.
Control selected tool, direction, rotation, processing feed, jump points and oscillation from the right parking position.
Return at high speed, sand with the same tool, or pneumatically select a second tool for a different process on the return path.
Inspect all edges and corners after a tool, material, profile, program, coating or clamping change.
Link sanding defects and downstream rework to part family, tool stack, direction, speed, jump settings and abrasive condition.
Usage by surface
MDF, wood, primer and lacquer each receive their own tools, motion program and rejection limit.
Select slotting, support and tool approach from the milled texture, then prove the edge under the actual primer.
Species, moisture, long grain, end grain and final colour define the opposing-rotation recipe and corner limit.
Use conservative tool support, feed and jump points so the surface is prepared without exposing the substrate.
Cure, film build, edge geometry and final gloss determine the scratch and breakthrough standard.
Guides, tips and techniques
This application framework supports qualified industrial teams and does not replace MB operating, programming, service or safety documentation.
Bring drawings, smallest and largest parts, profile families, corner limits and the surfaces available for pneumatic clamping. Include raw, accepted and rejected coated samples.
During development, record what the first direction contributes before making the return productive. Add opposing direction or a second tool only when it solves a named fibre, scratch or coating problem.
A full-height cylindrical brush maximizes one continuous field. Two 100 mm tools can separate grits or geometries. Chamfered tools improve access to selected contours. Qualify the stack as one system.
Engagement and disengagement positions depend on part length, profile, tool diameter, direction and corner standard. Store them in the released program and first-off any meaningful change.
Verify the correct part, support surface, pressure-bar contact, program, tool position, extraction and clear work zone before the cycle. Use MB documentation for all setup limits.
MB allows several workpieces to be clamped side by side when their combined long-side length fits the selected work area. The group receives its own loading, spacing and acceptance trial.
A fibre left only on one direction, a softened corner, a repeated scratch or coating breakthrough points toward different controlled reviews. Do not correct every symptom with extra passes.
Maintenance follows MB schedules for brushes, spindles, oscillation, carriage travel, pressure bar, pneumatic positioning, extraction and safety devices. Guarded service remains authorized work under prescribed isolation.
Deployment sequence
Baseline handling and finish loss, prove the full geometry, select the correct work area and protect the accepted tool/motion programs.
Record manual movement, setup, sanding time, corner correction, touch-up, abrasive changes and difficult part families.
Run representative long, tall, profiled, end-grain and coated edges through candidate tool stacks and motion programs.
Match 1,100, 2,400 or 3,600 mm configuration to the part envelope, multi-part strategy, floor space and output target.
Prepare loading, support, clamping, extraction, tooling, inspection, training and exception routing.
Control tools, jump points, speeds, first-off checks, maintenance and downstream finish feedback.
Deployment strategies
The three working-area lengths change more than maximum part size; they define support, grouped loading, footprint and the time structure of every cycle.
The 1,100 mm working-area version supports smaller doors, panels and grouped components where stationary clamping and a controlled travelling aggregate replace manual part movement.
The 2,400 mm version expands the supported edge range for larger doors, windows, stair parts and panels while preserving programmed carriage motion and pneumatic clamping.
The 3,600 mm version addresses very long components or productive side-by-side loading where the combined long-side length remains within the working area.
Business-case framework
Include handling, edge yield, coating rework, tooling, utilities, training and only the productive-return strategies proven on real parts.
Measure present effort to carry, guide and stabilize large workpieces, plus the time spent correcting inconsistent pressure or travel.
Include re-sanding, primer repair, edge breakthrough, visible scratch, rounded corners and remakes after finishing.
Use demonstrated full-height, stacked and chamfered tools, abrasive life, motor load, pneumatics and extraction from the selected proposal.
Credit only the two-direction, two-tool or side-by-side strategies that repeat the accepted result without increasing handling or rejection.
