The finishing accuracy of polishing is determined by the condition of the polishing pad.
The basics of polishing involve the maintenance and management of the precision of the polishing pads. It is dangerous if symptoms such as the following are observed.
Isn't this something you've experienced? - The polishing time has increased. - Decreased yield (the workpiece edge becomes rounded). - There are times when flatness is compromised. While the condition of the polishing material and the polishing processing conditions also have an impact, let's first check if the accuracy of the PAD has deteriorated. The basic idea of polishing is that the accuracy of the polishing PAD is transferred to the workpiece. In many cases, a DP correction carrier is used for PAD correction. However, it is often used without much thought, and the most important point, "correction," is frequently not done properly. To determine if the correction carrier is suitable, please check the following: - Is the PAD designed to be correctable? - Is a DP that can dress the PAD being used? - Is the overall thickness of the correction carrier uniform? If you experience any of the following after using the correction carrier in polishing: - The polishing rate does not recover. - The yield does not improve (does not return). - Changes in the PAD surface condition are not noticeable. Please feel free to consult with us. If you have been using it for a long time without maintenance, the correction capability may have been lost.
