Do you choose the cutting wheel based on its color? Will the difference in color affect the performance of the cutting disc? There are orange, dark yellow, and even pink cutting wheels on the market. Are these normal cutting discs?
In fact, the color of the cutting wheel can be adjusted. The two most commonly used colors on the market are black and green. Many customers will ask which of the two colors is better and how to choose. Today, let's take a look at where the colorful colors of the cutting disc come from.
1. The color of the abrasive itself
The type of abrasive naturally has a direct impact on the cutting wheel. Abrasives with high strength can effectively improve the performance of the cutting disc. During the production process, the color of the abrasive itself will also affect the color of the cutting wheel. For example, white is white aluminum oxide, black-green is silicon carbide, and black is brown aluminum oxide.
2. Binder color
Abrasives like green silicon carbide will not appear green during the production process. They need to be fired at a certain temperature before they will appear green. The color of the cutting disc will appear green during the firing process. Instead, it is the color of the binder with a larger proportion. Commonly used binders are mainly resins, rubbers... These binders also represent different characteristics.
3. Dye color
The color of the cutting wheel is mainly dyed by the cutting disc manufacturer to distinguish the model or other purposes. Dye is added during mixing to make the cutting wheel present the desired color. The color of the dye itself does not have a big impact on the properties of the cutting disc. It is mainly because the color is beautiful and more attractive.
Using the color of the cutting wheel to distinguish the abrasive type is a simple method, but it is also a method that is easy to make mistakes. Because the color of the cutting disc on the market not only appears in the color of the abrasive, but also the color of the binder or dye, and even the density of the pores will affect the visual effect. When the formula is adjusted, the color may change accordingly, or it may not change. What's more, color is one-sided and it is easy to be affected by external factors.
If you want to judge whether your cutting wheel is suitable, you still need to check the five factors of the trademark: abrasive, particle size, bonding, organization, and bonding agent. These are the key factors that really affect the grinding effect. Those particularly bright colors cannot improve the performance of the cutting disc. Please keep your eyes open when choosing!
