Polishing is a type of operation that utilizes abrasive particles or other materials to cut or abrade 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.

The characteristics and types of polishing wheels

Abrasive machining can be further divided into two categories: fixed abrasive machining and free abrasive machining.

Fixed abrasive machining: abrasive particles are fixed by other materials, usually with good cutting and removal forces

Free abrasive machining: The abrasive particles are located between the processed object and the carrier, and the carrier is used to grind the relative motion of the workpiece, usually with good surface roughness.

These two major types of processing methods have their own tools suitable for polishing operations.

Common tools for polishing

Fixed abrasive processing:

Sandpaper, abrasive tape, polishing tape, non-woven wheel, rubber grinding wheel, PVA grinding wheel, abrasive cloth wheel, resin grinding wheel.

● Free abrasive machining:

Abrasive particles: abrasive fluid, diamond paste, polishing wax, elastic sandblasting particles.

Vehicles: cloth wheel, hemp wheel, wool wheel, metal plate, polishing pad.

Among them, those with a wheel shape are:

● Containing abrasive particles: non-woven wheels, rubber grinding wheels, PVA grinding wheels, abrasive cloth wheels, resin grinding wheels.

● Excluding abrasive particles: cloth wheel, hemp wheel, wool wheel.

Various types of polishing wheels

Polishing wheels without abrasive particles will be designed based on the material characteristics of different shapes being polished. Using different weaving methods and combinations to present different shapes.

But from the appearance alone, polishing wheels containing abrasive particles are not easily distinguishable. It should be distinguished based on the binder, structure, abrasive particles, and composition method. If there is a slight difference, its polishing may have a completely different effect.

Characteristics of polishing wheels

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 abrasive belts 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 use in automated grinding and polishing operations. If consumables such as abrasive belts were originally used, it is advisable to consider the possibility of replacing them with polishing wheels when considering switching to automation.
