A friend called to inquire if it is necessary to continuously add water when using QMAXIS alumina polishing solution for polishing?
This issue requires distinguishing between several situations:
In one case, when the grinding disc has a speed of over 500 revolutions for rapid polishing, it is necessary to add lubricant or water. However, it is important to note that the flow rate of the lubricant or water added should not be too fast, otherwise it may easily wash away the alumina grinding particles and reduce the grinding and polishing efficiency.
Also, for metal materials that are prone to oxidation, polishing with water is necessary to make them easily oxidized. Therefore, in this case, alcohol or lubricating oil should be used to ensure that the polishing cloth is always wet. In addition, it is important to note that impurities that have been ground should not accumulate on the polishing cloth.
In general, it is better to maintain the polishing speed above 200 rpm for cutting efficiency. QMAXIS aluminum oxide polishing solution or polishing paste should be sprayed or applied to the center of the rotary table as much as possible for better utilization.
