Product Details

What is No.4 Belt Brushing & Grinding Machine

A No.4 Belt Brushing & Grinding Machine is a stainless steel surface finishing machine used to create a fine, uniform brushed or satin texture on sheets, plates, or coils. It uses abrasive belts to grind and brush the metal surface, helping remove minor defects and produce a clean decorative finish. This machine is widely used for elevator panels, kitchen equipment, home appliances, decorative stainless steel sheets, and architectural metal products.

Stainless Steel No.4 Belt Brushing & Grinding Process

1. Material Preparation

Stainless steel sheets, plates or coils are selected before processing. The material surface should be flat, clean and free from deep scratches, dents, rust, heavy oil stains or serious surface defects.

2. Surface Cleaning

Before grinding and brushing, the stainless steel surface should be cleaned to remove oil, dust, fingerprints, glue residue and other impurities. Proper cleaning helps prevent uneven grinding marks and improves the final No.4 surface quality.

3. Abrasive Belt Selection

The correct abrasive belt grit is selected according to the required surface effect. Coarser grit is used for stronger grinding or surface correction, while finer grit is used to produce a smooth and uniform No.4 brushed finish.

4. Feeding and Alignment

The stainless steel sheet or coil is fed into the machine through the conveyor system. The material must be properly aligned to ensure straight brushing direction and consistent surface grain.

5. Belt Grinding

The abrasive belt grinds the stainless steel surface to remove minor scratches, oxide marks and uneven surface layers. Grinding pressure, belt speed and conveyor speed are adjusted according to material thickness and required finish.

6. No.4 Brushing

After grinding, the brushing process creates a fine, uniform satin line texture on the stainless steel surface. This step forms the typical No.4 decorative finish used for elevator panels, kitchen equipment, appliances and architectural decoration.

7. Cooling and Lubrication

For wet-type machines, grinding oil, coolant or water-based liquid is used during processing. This helps reduce heat, control dust, protect the abrasive belt and improve the smoothness of the brushed surface.

8. Surface Cleaning and Drying

After brushing, the surface is cleaned to remove grinding residue, oil, dust and metal particles. The material is then dried to prevent water marks, oil stains or surface contamination.

9. Protective Film Laminating

If required, a protective film is applied to the finished No.4 stainless steel surface. This protects the surface from scratches during handling, cutting, transportation and further processing.

10. Final Inspection

The finished material is inspected for grain uniformity, straight line direction, surface cleanliness, scratches, waves and overall appearance. Qualified sheets or coils are then ready for packaging or further production.

Key process Advantages

Professional No.4 Brushing System

The machine is equipped with high-performance abrasive belt grinding units designed for stainless steel surface brushing. It can produce a fine, uniform No.4 satin finish suitable for decorative and industrial applications.

Uniform Grinding Pressure

Stable belt pressure helps the abrasive belt contact the stainless steel surface evenly. This ensures consistent grain depth, uniform line texture and stable surface quality across the full sheet width.

Adjustable Belt Speed and Feeding Speed

The machine allows adjustment of abrasive belt speed and conveyor feeding speed according to different materials, thicknesses and finish requirements. This helps achieve better control of surface texture and production efficiency.

Improved Production Efficiency

Compared with manual brushing or polishing, the machine provides faster, more stable and more consistent surface finishing, helping customers reduce labor cost and improve product quality.

Quality Inspection Standards

surface roughness

typical target surface is commonly around Ra 0.4–0.8 μm

the working thickness is 0.5–3 mm, working width is 1250 mm or 1550 mm, and feed speed is 5–15 m/min.
