Product Overview

The Four Roller Scotch Brite Grinding Machine is a professional metal surface finishing machine used for stainless steel decorative sheet processing. Compared with normal abrasive belt grinding, Scotch Brite finishing creates a softer, finer and more even matte texture, making the surface suitable for high-end interior decoration, elevator panels, appliance panels and architectural stainless steel products.

With four roller grinding units, stable feeding, adjustable roller pressure and variable conveyor speed, the machine helps achieve consistent surface quality across the full sheet width. The system can also be equipped with dust collection, cleaning, drying and optional protective film laminating according to customer requirements. This is for the Lebon company website context provided by you.

Working Process

Feeding Section
The stainless steel sheet is fed into the machine through the conveyor system. Stable feeding keeps the material flat and ensures consistent surface processing.

Scotch Brite Roller Grinding Section
Four groups of Scotch Brite rollers process the sheet surface continuously. The rollers create a soft, fine and uniform matte texture while reducing minor surface marks.

Pressure and Speed Adjustment
Roller pressure and conveyor speed can be adjusted according to material thickness, surface condition and required SB finish effect.

Dust Collection / Cleaning Section
For dry processing, dust collection helps remove grinding dust. Cleaning equipment can also be added to remove surface residue and improve finished sheet cleanliness.

Film Laminating Section
If required, a protective film is applied to the finished SB surface to prevent scratches during handling, cutting and transportation.

Finished SB Surface Output
The finished stainless steel sheet has a smooth, soft and uniform Scotch Brite surface suitable for decorative and industrial applications.

  Quality Control

  
  

  
  

Surface Uniformity Check

The finished stainless steel surface should have a soft, uniform and matte SB / Scotch Brite finish. The texture should be even across the full sheet width, without obvious bright/dark areas, patchy marks or uneven grinding zones.

Roller Contact Inspection

Check whether all four Scotch Brite rollers contact the sheet surface evenly. Uneven roller contact may cause different surface textures between the center and edges of the sheet.

Grain and Texture Consistency

The surface texture should be fine, smooth and consistent along the feeding direction. There should be no irregular lines, roller overlap marks, vibration marks or obvious direction changes.

Surface Defect Inspection

The finished sheet should be free from:

• Deep scratches

• Roller marks

• Burning marks

• Patchy areas

• Dust marks

• Oil stains

• Uneven matte texture

• Edge difference

• Surface contamination

Roller Pressure Control

Roller pressure should be adjusted according to material thickness, surface condition and required SB finish. Excessive pressure may create deep marks or surface heat, while insufficient pressure may result in incomplete finishing.

Conveyor Speed Control

The feeding speed should remain stable during production. Unstable speed may cause uneven texture, repeated marks or inconsistent surface appearance.

Scotch Brite Roller Condition

The roller surface should be checked regularly for wear, clogging, damage or uneven abrasion. Worn or contaminated rollers can cause poor surface consistency and visible defects.

Dust Collection and Cleaning Check

For dry SB grinding, the dust collection system should work properly to remove grinding dust. The finished surface should be clean and free from abrasive particles or metal dust.

Full-Width Consistency Check

Inspect the left side, center and right side of the sheet. The SB finish should remain consistent across the full working width, with no obvious edge difference.

Protective Film Inspection

If film laminating is used, check that the protective film is flat and well attached. There should be no bubbles, wrinkles, dust particles or scratches under the film.

Final Sample Approval

Before mass production, one sample sheet should be processed and approved. After approval, the same roller type, pressure, feeding speed and machine settings should be maintained for stable production quality.

Short Technical Version

The LEBON Four Roller Scotch Brite Grinding Machine should produce a soft, uniform and matte SB finish on stainless steel sheets. Quality control should focus on roller pressure, roller wear, feeding speed, dust collection, surface cleanliness and full-width consistency. The finished surface should be free from scratches, roller marks, burning marks, patchy areas, oil stains and dust contamination.
