Product Details

8K mirror polishing machine is designed for producing high gloss mirror finish on stainless steel, titanium and aluminum sheets with eco-friendly acid-free wet polishing technology.

What is 8K Mirror Finish?

“8K” represents a high-grade mirror polishing standard with extremely high reflectivity and ultra-low surface roughness.

“K” refers to the mirror reflectivity grade after polishing
Higher grades such as 10K or 12K indicate even finer surfaces
8K mirror finish is already sufficient for most premium decorative and industrial applications

Typical 8K mirror surface characteristics:

High Gloss Reflectivity (>80° Gloss Value)
Surface Roughness: Ra ≤ 0.05 μm
Clear and distortion-free reflection
Uniform and directionless mirror appearance

The 8K super mirror effect creates brightness and spacious visual effects while avoiding the harsh “light pollution” commonly associated with glass mirrors.

Advanced Wet Polishing Technology

LEBON uses advanced wet polishing technology to achieve a smoother, more consistent, and more stable mirror surface.

Compared with dry polishing, wet polishing provides:

Better cooling performance
Reduced oxidation and discoloration
Lower risk of vibration marks and surface defects
Improved polishing consistency
Longer abrasive consumable life
Cleaner production environment

The machine is equipped with an environmentally friendly polishing compound recycling system. The polishing liquid continuously circulates through an automatic filtering unit and is reused after purification, minimizing waste and reducing operational costs.

Production Process Flow

1. Material Preparation

Suitable for:

Stainless Steel 200 / 300 / 400 Series
Titanium Sheets & Plates
Aluminum Sheets & Coils

The material surface should be flat, clean, and free from oxidation spots or deep scratches.

2. Surface Pre-Treatment

Chemical or physical cleaning processes remove:

Oil
Dust
Oxide layers
Surface contamination

3. Grinding & Polishing Process

Coarse Grinding

80–120 grit abrasive belts remove:

Oxidation layers
Welding marks
Surface scratches

Medium Grinding

400–600 grit abrasive belts refine the surface and remove coarse grinding traces.

Fine Grinding

800–1000 grit abrasive belts prepare the material for mirror finishing.

Super Mirror Polishing

Special buffing felts combined with LEBON eco-friendly polishing compound produce a deep, highly reflective Super 8K mirror finish.
