Stainless Steel Surface Brushing Equipment: Digital Regulation, Creating High-end Texture

Stainless steel brushed surfaces, with their matte texture, fingerprint resistance and decorative advantages, are increasingly used in architectural decoration, high-end kitchen and bathroom and other fields. Industry standards clearly require that the surface roughness of brushed surfaces should be controlled within the range of 0.5-1.5μm Ra, and the texture uniformity deviation should be ≤10%. Through the precise control of abrasives and the optimization of motion trajectory, this stainless steel surface brushing equipment realizes the digital regulation of the brushing process, and its technical parameters fully meet the GB/T 25372-2010 Class V precision requirements after third-party testing.
The core technical architecture of the equipment consists of a three-stage system of "pretreatment - brushing - finishing": the front high-strength wide abrasive belt station adopts servo lifting control, and can select 80-600 mesh abrasive belts according to the surface state of the base material to efficiently complete oxide scale removal and pre-texture processing; the middle brushing unit is equipped with four sets of grinding heads with adjustable angles (0-45°), supporting various texture modes such as straight grain and random grain, and the abrasive belt linear speed can be steplessly adjusted within the range of 5-30m/min, ensuring the texture spacing error ≤0.1mm; the rear finishing roller group adopts imported nylon filaments to further reduce the surface roughness to below Ra0.3μm.
Multi-scenario empirical data verifies the equipment performance: in the processing of elevator car panels, the equipment achieves a straightness error of ≤0.2mm for 1200mm length brushed textures, and the surface gloss is stably between 30-50GU; for the processing of stainless steel plates, the texture consistency of a single batch of 200 products reaches 98%, and the fingerprint residue is reduced by 85% compared with mirror treatment, fully meeting high-end industry standards. The equipment adopts an integral welded frame and sandblasting treatment process, which increases rigidity by 30%. Combined with a vacuum adsorption conveying system, it can process film-coated workpieces as small as 50*50mm, with a film integrity rate of 99%, greatly reducing the cost of subsequent processes. Energy consumption tests show that the power consumption per unit area of the equipment is only 65% of that of traditional equipment. Combined with recyclable PPT filter screens, the annual consumable cost is saved by more than 20,000 yuan.
