In the field of metal processing, flat wire drawing technology has become an important part of high-end manufacturing due to its unique decorative and functional properties.

As one of the core technologies of surface treatment, its process principles and application scenarios are worth exploring in depth.

Process principle and technical points: Material adaptability is suitable for metals such as stainless steel, aluminum alloy, titanium alloy, etc.

Through high-speed friction of sand belts or nylon wheels, uniform linear textures (commonly including straight wires, tangled wires, snowflakes, etc.) are formed on the surface, and the roughness range is usually controlled within Ra 0.1~1.6 μ m.

Core parameter control of sand belt mesh: Coarse grinding (80~240 mesh) is used for deburring, fine grinding (400~800 mesh) achieves fine texture, and mirror level needs to be above 1200 mesh.

Walking speed and pressure: Excessive speed can easily cause texture blurring, while uneven pressure can result in "yin and yang surfaces", which need to be dynamically adjusted according to the material thickness (such as recommending 6m/min+50N pressure for 1mm stainless steel plate).

Technological advantages and industry value: Decorative: Compared to spraying or electroplating, brushed texture has a more textured and less prone to detachment, widely used in electronic product casings, luxury accessories, etc.

Functionality: By eliminating micro scratches, the corrosion resistance of materials can be improved (such as extending the salt spray test life of ship decks by 30% after drawing).

With the increasing demand for environmental protection, dry drawing (without coolant) and AI adaptive adjustment technology are becoming new directions, promoting the development of processes towards higher efficiency and precision.
