Calibration Sanding vs Polishing Sanding

What is the Polishing Sanding for Plywood

Polishing sanding is a light surface sanding process with minimal material removal. It eliminates burrs, fiber fuzz, and glue spots, making the board smoother, finer, and more uniform. This process improves surface flatness, ensuring the board is ready for painting or lamination and preventing bubbling when applying decorative paper or veneer.

Which Type Plywood Need Polishing Sanding

• Plywood & Blockboard – Surface preparation before lamination or painting.

• MDF & Particle Board (PB) – Essential polishing step before painted furniture production.

• Solid Wood Products – Surface finishing for furniture, doors, and handicrafts.

• Flooring & Cabinet Panels – Fine sanding before decorative surface finishing.

Smooth & Fine Surface – Improves touch and appearance.
Better Adhesion – Enhances bonding for paint, veneer, or decorative paper.
Improved Flatness – Reduces defects like bubbling or uneven surfaces.
Higher Product Value – Ensures premium quality for furniture and interior panels.

Polishing Sanding Machine – Key Features

1. Low Material Removal

• The sanding rollers apply light pressure with moderate power and smooth transmission to avoid damaging the board surface.

• Performs light sanding mainly to remove burrs, fiber fuzz, and minor surface imperfections, without the heavy sanding required by thickness calibration.

2. Uniform Sanding

• Equipado com rubber sanding rollers ou combination sanding heads (roller + pad).Conforms to minor surface undulations, preventing over-sanding from hard rollers,and ensures even removal of burrs and fibers, producing a smooth and consistent surface.

3. High-Quality Surface Finish

• Usos fine grit sanding belts (typically 180#–320#) to achieve a delicate, flat, and smooth finish,Ideal para painting, lamination, or veneer application where surface quality is critical.

This machine is designed for plywood, MDF, particle board, solid wood panels, flooring, and cabinetry, providing a professional surface finish ready for decorative or painting processes.
