"EVERFLO" is a concentrated liquid additive that enhances the performance of various abrasives such as cerium, zirconium, and alumina. It is effective in various polishing slurries used in grinding to precision polishing processes. This product forms a surfactant film on the particles of the abrasive, suppressing the bonding between particles and improving re-dispersibility. In addition to dispersion effects, improvements in surface accuracy have also been observed. 【Effects】 ■ Improved re-dispersibility ■ Reduction of scratches, scuffs, and discoloration ■ Improvement in surface accuracy ■ Enhanced cleanability, among others *For more details, please feel free to contact us.

Colloidal silica is an excellent polishing agent for final polishing and is used for finishing a wide range of materials such as optical glass, quartz glass, filter glass, and crystals. However, it is also true that due to the nature of colloidal silica, great care must be taken to avoid "drying and adhesion." In fact, there are already movements to find alternatives to colloidal silica as a countermeasure against drying and adhesion. *For more details on the column, please refer to the related link.

It has been nearly half a century since our company, Yachiyo Micro Science, began selling cerium oxide polishing material "MIREK" manufactured by Mitsui Mining & Smelting Co., Ltd. During this long period, the needs have changed, starting from polishing agents for construction glass, and evolving through applications in eyeglass lenses, camera lenses, LCD glass, hard disk substrates, and now being used in cutting-edge fields such as EUV photomask blanks and optical filters. The main features of our product are its stability in quality and high classification accuracy. We invite you to evaluate it. [Features] - Stability in quality - High classification accuracy *For more details, please feel free to contact us.

We would like to introduce the "Mirek HL Series (2-element product) Slurry Type" that we handle. Currently, there is an increasing number of cases where high-quality surface precision is required for applications ranging from optical glass, quartz glass, filter glass, to crystals. This polishing material is suitable for those who are seeking a quality level beyond the current standard (improvement in surface precision Ra, reduction in defects, etc.) or for those who want to improve compatibility with polishing pads that have poor performance (weak chemical resistance, short pad life, etc.). 【Recommended for】 ■ Those who are seeking a quality level beyond the current standard (improvement in surface precision Ra, reduction in defects, etc.) ■ Those who are struggling with drying adhesion when using colloidal silica ■ Those who want to improve compatibility with polishing pads that have poor performance (weak chemical resistance, short pad life, etc.) *For more details, please feel free to contact us.

The occurrence of crashes due to pads peeling off or misaligning during polishing not only leads to damage to the substrate and the need for pad replacement but also requires cleaning of the polishing machine and removal of debris, resulting in a significant decrease in work efficiency. This issue can be resolved by using strong adhesive tape; however, a disadvantage is that it can be difficult to remove the pads. Therefore, the choice of double-sided tape may vary depending on the customer's objectives, applications, and priorities. At FILWEL, we mainly offer tapes from three manufacturers. We can also prepare options beyond these three types according to the customer's needs, so please feel free to consult with us. *For more details, please do not hesitate to contact us.*

Additionally, we offer a variety of additives, making it possible to meet many precision requirements (such as improvements in normality, dispersibility, and re-dispersibility). 【Features】 ■ Stable procurement and supply ■ Average particle size is approximately 0.5 to 1.5 μm ■ High classification accuracy and stable quality ■ A variety of additives are available *For more details, please feel free to contact us.

The basics of polishing emphasize the importance of precision management of the polishing pad, and a commonly used tool for maintaining that precision is the DP-equipped correction carrier. Using a correction carrier not only allows for precision adjustments but also plays a crucial role in cleaning the pad. However, depending on the situation, there are significant and dangerous disadvantages when it comes to polishing. 1. Rust 2. Slow polishing speed on the upper side 3. Requires two people for setup (or needs to be set up with a machine) Among these three, the common factor related to "different polishing speeds on the upper and lower sides" and "setup issues" is "weight." When considering setup, it’s easy to imagine that a lighter weight can lead to improved workability and safety, even with larger equipment. On the other hand, what is the relationship between the polishing speeds of the upper and lower sides and weight? Polishing conditions are set in grams. Therefore, the weight of the correction carrier can negatively impact dressing and truing. The heavier the carrier, the greater the pressure applied to the lower side, leading to changes in the surface condition of the upper and lower pads. It is undoubtedly better for the correction carrier to be lighter in order to maintain as similar a condition as possible. Would you like to try an ultra-lightweight correction carrier for free to counteract such disadvantages?

Q: What are the raw materials for the correction carrier? A: The material of the carrier is resin. Typical correction carriers use cast iron, so ultra-lightweight versions cannot be made with the same specifications. Q: Are there any specified machine manufacturers for using the correction carrier? A: There are no specified manufacturers. It can be created to match your equipment. Q: What kind of information (drawings, etc.) is needed for production? A: We are confirming the carrier gear information and the size of the base plate. We will provide additional materials regarding the necessary information. Q: How long does it take from order to delivery? A: It takes about 2 months from the order. Q: Do you have specific improvement data? A: The dressing time has been reduced from 2 hours to 10-30 minutes. Improvement of workpiece edge drooping. There are also improvements in the polishing rate after dressing. Q: How much does it cost? Is there a price list? A: The price varies depending on size and specifications, so please contact us first. Q: Can I try it out? A: If our existing patterns are available, we can lend them out for up to 1 month.
