The Differences, Advantages And Disadvantages Between Diamond Soft Grinding Discs And Metal Grinding Discs

一、 Diamond  polishing pad

The formula of "abrasive+resin bond" is a flexible abrasive tool made of diamond as abrasive and resin and other composite materials as bond. Large abrasive particles can be seen inside. The back side is pasted with velcro cloth, which is connected to the grinding machine through the grinding joint which is also pasted with velcro cloth.

Advantages: The price is cheaper than that of metal sheet. Because of the fixed buffer effect of resin, it is not easy to scratch the stone when grinding, and there will be no scratch that is difficult to repair. The requirements for the later connecting grinding sheet are low.
Disadvantages: Although the sharpness of the diamond soft grinding disc is very high, its grinding ability is still inferior to that of the metal grinding disc. Moreover, the hardness of the resin is lower than that of the stone after all. When it encounters a large height difference, it is easy to break due to the violent collision between the machine and the cutting edge of the stone due to the high-speed operation.

二、 Metal floor polishing pad

 

Using the formula of "metal+abrasive", the abrasive is cast into the metal base.

Advantages: It is very sharp and has strong cutting ability. It can easily level the large height difference.

Disadvantages: If the grinding is not careful, it is easy to leave scratches that are difficult to repair. The requirements for the subsequent lapping are high.

三、 Difference between diamond polishing pad

According to the above analysis of diamond soft abrasive discs and metal abrasive discs, we can know that the differences between the two are as follows:

1. Leveling effect
The leveling effect of the grinding disc is also its optimization ability. Because the soft diamond grinding disc is added with resin composite material, it is relatively soft, so the leveling effect is good when grinding, and it will not leave scratches on the stone, while the metal grinding disc is easy to leave scratches.
2. Sharpness
From the perspective of sharpness, the sharpness of diamond soft grinding discs is not as strong as that of metal grinding discs.
3. Subsequent joint grinding
From the above introduction of the two kinds of abrasive discs, the requirements of the diamond soft abrasive discs for the subsequent connecting abrasive discs are low, while the requirements of the metal abrasive discs for the subsequent connecting abrasive discs are high.
4. Grinding disc price
In terms of price, the price of diamond soft grinding discs is lower than that of metal grinding discs. The difference between the two kinds of grinding discs is analyzed. So how to choose grinding discs when purchasing? Next, let's talk about the selection principles of diamond soft abrasive discs and metal abrasive discs.

 

四、 Selection principles of diamond soft grinding discs and metal grinding discs

1. For general height difference, select diamond soft grinding disc; For particularly serious height difference, such as exaggerated to 1 cm, choose metal grinding discs.
2. For soft marble and limestone, diamond soft grinding discs are selected. The metal grinding discs have too strong grinding ability and are easy to be overground.
3. Diamond soft grinding discs can solve the cutting problem of most natural stones, and metal grinding discs can be selected for particularly hard stones.
4. It is recommended to use metal grinding discs on terrazzo and cement floors, but not diamond soft grinding discs.
To sum up, the difference between diamond soft grinding discs and metal grinding discs lies in the leveling effect. The leveling effect of diamond soft grinding discs is better when grinding, while the metal grinding discs are easy to leave scratches; In sharpness, the sharpness of diamond soft grinding discs is not as strong as that of metal grinding discs. In addition, when the metal grinding disc encounters relatively smooth granite, it is easy to slip and cannot open the edge. At this time, the smooth surface of granite can be polished with an angle grinder+grinding wheel, and then the metal grinding disc can be used.
