Edges and Perimeter Areas
Edges can be overcut before broad flat areas reach the required condition, sending parts back for coating or repair.
Sealer and Primer Sanding with Controlled Surface Contact
For furniture, cabinet, and wood-door coating lines, primer sanding must level the surface without cutting too deeply at edges, profiles, or recessed areas.
MASA matches the contact method, machine path, and abrasives to the coating and workpiece, then checks the configuration with supplied project material before shipment.
Where Primer Sanding Turns into Rework Risk
Primer problems often begin where one contact setting meets surfaces with different geometry or coating build.
Profiles, Grooves, and Open Texture
Fixed contact can leave recessed zones underworked while pressing too hard on raised profiles or exposed texture.
Sanding Marks Before the Next Coat
Uneven preparation can leave visible marks or an inconsistent surface for the following coating stage.
Control Contact Where the Coating Is Most Vulnerable
Position the Sanding Head for Controlled Contact
For a dedicated floating-primer route, magnetic-scale positioning works with a ball-screw lifting system to establish the sanding-head position. This gives technicians a defined mechanical starting point before material trials.
Lift Individual Pads at the Edge
On applicable piano-key configurations, a mechanical travel switch detects the workpiece and an optical encoder tracks its position. Individual pads lift as the perimeter reaches the contact zone, reducing unnecessary pressure at the edge.

Match the Sanding Route to the Coating Structure
Full-sealed UV and open-pore primer require separate process decisions rather than one repeated recipe.
UV Full-Sealed Primer
Review the curing stage, surface geometry, removal target, and next coating operation. Machine contact and abrasives are then selected against the actual coated sample.
Open-Pore Primer
Where the finish must retain visible texture, the route must follow pores, grooves, and raised profiles without treating every area as a flat surface.
Match the Machine and Abrasive to the Process
Dedicated Primer Sanding Route
A dedicated primer route combines the appropriate head-positioning method, sanding contact, and abrasive sequence around the coating and workpiece geometry.
One Machine for Raw Wood and Primer
When one machine must handle both operations, MASA can evaluate a wide-profile configuration with independently adjustable sanding groups and settings for raw wood and primer.
Abrasives from MASA’s Own Consumables Plant
Available abrasive-strip grits include 180, 240, 320, 400, and 600, together with matching brush materials. The final sequence follows coating review and material testing.
Confirm the Setup with Supplied Material
Identify the Coating and Workpiece
Review coating type and curing stage, substrate, dimensions, surface geometry, current defects, and target finish.
Select the Process Combination
Match the machine, sanding-head or group configuration, contact method, and abrasive options to the task.
Run the Material Trial
Process the supplied sample and inspect flat areas, profiles, grooves, and perimeter edges before final adjustment.
Confirm the Pre-Shipment Configuration
Complete the configured material run-off alongside voltage, leakage-protection, functional, and appearance checks. Video factory inspection and onsite factory inspection are supported.
