Background
The ceramic cup wheel is a more efficient solution for edge work, reducing steps and labor costs. However, there is a common issue with ceramic cup wheels on the market: the surface of ceramic cup wheel will appear scorched black area after continuously grinding for a period of time. Depending on different scenario, the burning issue can affect the efficiency and effectiveness in different extent.
Ashine continually updates formulas and tests their efficiency to tackle the problem of burning ceramic surface and improve the tooling performance. This report was conducted to compare Ashine SuperEdge with one of the most popular ceramic cup wheels on market, Ashine upgraded ceramic cup wheel showed strong data performance in resolving such challenges, as well as a significant potential to improve edge work efficiency and ease of transfer to polishing steps.

Surface Condition |
Soft concrete floor with Moh’s hardness of 3-4 |
|
Testing Machine |
Φ125mm hand-held angle grinders |
Test Process
1. Firstly, use the Φ125 hand-held angle grinders with swirl cup wheel 16# to grinding the concrete floor No.1 and No.2 to the appropriate extent.
Before the Test
2. Secondly, use the grinders (2200W, 6700RMP) with test sample to grinding the test area for ten minutes. (Floor No.1 for Sample No.1 and Floor No.2 for Sample No.2)
After the Test
3. Observe the wheel surface of samples No.1 and No.2 after grinding with optical microscope to verify if there is any scorched black area on the surface.
4. Collect the numerical values of the protrusion height of diamond grits of samples No.1 and No.2, as well as the dust extracting content of samples No.1 and No.2 during the grinding process by Blastrac vacuum, in order to compare the aggressiveness and grinding efficiency of two samples.

Sample |
Tooling surface after grinding |
|
No.1 |
The bond is scorched black, especially in the area around the diamond, which shows the bond has a poor temperature resistance. |
|
No.2 |
It cannot be found the scorched black area on the surface of Sample No.2#, which shows the bond has a high temperature resistance. |
According to the wheel surface condition comparison, it can be found that Sample No.2 has a better temperature resistance, indicating that Sample No.2 can minimize the effect from burning issue and keep its performance optimal.
