Airway polishing wheels and ordinary polishing wheels have significant differences in structure, function, and applicable scenarios. At first glance, traditional polishing wheels are simply stacked and sewn together with several layers of fabric, while pneumatic polishing wheels are usually constructed around a metal clamping ring. However, there are more details behind it: perhaps the most significant difference between these types of polishing wheels lies in the "bias" process.
1. Different structural designs
-Airway polishing wheel: Due to the many wrinkles on the wheel body, these airways penetrate the wheel body, allowing air circulation. Its structure is usually looser, with gaps in material distribution.
-Ordinary polishing wheel: The wheel structure is compact, without specially designed air ducts, and the material (such as cloth, hemp, fiber, etc.) is tightly wrapped or pressed, making the overall structure more solid.
2. Differences in heat dissipation performance
-Airway polishing wheel: Airway design can significantly enhance heat dissipation, reduce heat accumulation caused by friction during polishing process, avoid workpiece discoloration and deformation due to high temperature, and extend the life of the wheel body.
-Ordinary polishing wheel: The tight structure has poor heat dissipation, and long-term use can easily cause hardening of the wheel body and damage to the workpiece (such as metal annealing and burnt paint surface) due to high temperature.
3. Polishing efficiency and effect
-Airway polishing wheel: With good air circulation, it can reduce blockage when combined with polishing compound. Its wrinkles are like small storage bags, which effectively absorb polishing agent, maintain wheel surface activity, improve polishing efficiency, and have a more uniform surface. It is suitable for high precision polishing requirements (such as stainless steel, high-end furniture, automotive parts, etc.).
-Ordinary polishing wheel: The initial polishing force is strong, but the efficiency may decrease due to heat and debris accumulation, making it more suitable for rough polishing or scenarios with low heat dissipation requirements (such as polishing ordinary metal parts).
4. Applicable scenarios
-Airway polishing wheel: commonly used for precision workpieces, materials that are easily damaged by heat (such as aluminum alloy, plastic, high-end wood, medical equipment, musical instruments, automotive parts), or scenes that require long-term continuous operation (automatic polishing machine)
-Ordinary polishing wheel: suitable for general rough polishing, medium polishing, or materials with low heat dissipation requirements (such as steel parts).
In short, the core advantages of airway polishing wheels are heat dissipation and fine polishing, while ordinary polishing wheels focus more on basic polishing and cost-effectiveness. When choosing, it is necessary to judge based on the workpiece material, polishing accuracy, and operating intensity.
