What is polishing? Polishing is an operation that uses abrasive particles or other materials to cut or rub against workpieces. The main purpose is to improve surface roughness and enhance glossiness. Due to the use of abrasive particles, it still belongs to the field of abrasive processing in machining. Abrasive machining can be divided into two categories: fixed abrasive machining and free abrasive machining. Fixed abrasive machining: The abrasive particles are fixed by other materials, and usually have better cutting and removal forces ● Free abrasive machining: The abrasive particles are located between the workpiece and the carrier, and the carrier is used to grind the relative motion of the workpiece, usually with good surface roughness. These two categories of processing methods have their own tools suitable for polishing operations. Common tools for polishing Fixed abrasive machining: Sandpaper, sanding tape, polishing tape, non-woven cloth wheel, rubber grinding wheel, PVA grinding wheel, sanding Cloth wheel, resin grinding wheel.
● Free abrasive machining:
Grinding particles: grinding fluid, diamond paste, Polishing Wax, elastic sandblasting particles. Vehicle:Cotton Cloth Wheel, Sisal Wheel, wool wheel, metal plate, polishing pad. Among them, those with a wheeled shape include: ● Contains abrasive particles: non-woven Polishing wheel, rubber grinding wheels, PVA grinding wheels, sanding wheels, resin grinding wheels. ● Excluding abrasive particles: various types of cotton cloth wheels, linen wheels, wool wheels, and Polishing Buff Wheel.
A polishing wheel without abrasive particles will be polished according to the different shapes and material characteristics of the material being polished. Using different weaving methods and combinations to present different forms. But from the appearance alone, polishing wheels containing abrasive particles are not easy to separate. It should be distinguished based on the binder, structure, abrasive particles, and composition method. If there is a slight difference, its grinding and polishing may have completely different effects. The characteristic of polishing wheels is to make the outer circumference come into contact with the workpiece and exhibit high-speed rotation, possessing the characteristic of fast processing speed. In addition, depending on the size of elasticity, it is beneficial for processing various irregularly shaped workpieces. Usually, it has a self sharpening effect that gradually consumes and automatically generates new abrasive particles. Therefore, compared to polishing materials such as sandbelts and sandpaper, it can reduce the frequency of replacing consumables. At the same time, it can also reduce the generation and disposal costs of waste. It is worth noting that due to the above characteristics, polishing wheels are actually very advantageous for application in automated grinding and polishing operations. If consumables such as sandbelts were originally used, it may be worth considering the possibility of replacing them with polishing wheels when considering switching to automation.
