The surface of the suede pads we handle, including the pads, used for finishing polishing feels really smooth when you run your hand over it. Basically, suede pads for precision polishing have been developed based on synthetic leather used in bags, shoes, car seats, etc. The manufacturing method involves shaving the surface of the synthetic leather to create a suede-like texture, but when you magnify the surface, you can see countless tiny holes measuring several tens of microns, which contribute to the smooth feel. 【Features】 - Made by shaving the surface of synthetic leather to create a suede-like texture - When magnified, the surface has countless tiny holes measuring several tens of microns - The shape of the holes in the pad's structure is triangular - If the amount of surface cutting is small, small holes are created; if it is large, larger holes are formed *For more details, please feel free to contact us.

We would like to introduce a case where we performed "flocculation treatment." In the case of core-drilling wastewater, we neutralized and coagulated it using an alkaline type of water treatment, and then added oil floc. As a result, the aggregates became larger, and we were able to produce floc that could be easily filtered with a cotton handkerchief. Additionally, the same results were achieved even when mixed in. If you are dissatisfied with fine concrete or floc that does not settle after pH adjustment, please give it a try. 【Case Overview】 ■Challenges - Core-drilling wastewater is highly alkaline and difficult to discharge. - It contains concrete powder as well. ■Results - The aggregates became larger, and we were able to produce floc that could be easily filtered with a cotton handkerchief. *For more details, please feel free to contact us.

Would you like to try groove processing on suede pads? I believe suede pads are typically used in the final stages of polishing. Therefore, the finish of the polished surface is important, but depending on the workpiece, there may be differences between the upper and lower polished surfaces. While this is not always the case, there may be instances where the polishing liquid does not fully drain on the lower side. By performing groove processing on the lower pad, the polishing liquid can be evenly distributed. Additionally, if the workpiece is thin and light, there can be a phenomenon where it sticks to the upper side. This can be mitigated by performing groove processing on the upper pad. We offer groove shapes in addition to the standard rectangular shape, including U-shaped grooves. By making the edges of the grooves obtuse, we can reduce surface defects, and since the flow rate of the polishing liquid increases, uniform polishing can be achieved, resulting in improved precision. 【Features】 ■ Groove shapes: rectangular, U-shaped ■ Reduces surface defects ■ Improves precision *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.

What kind of double-sided tape is good for precision grinding pads? Precision grinding pads are used by adhering them to a grinding plate with double-sided tape. If they are not applied neatly, it can lead to unevenness or contamination. Since we are working in the realm of micrometers and nanometers, the application is very important. What is necessary for this application is double-sided tape. Even if the application is done perfectly, if there is an issue with the double-sided tape, the pad may peel off or shift during grinding. This can lead to a decrease in precision and an increased risk of crashing. *For more details, you can view the related links. Please feel free to contact us for more information.*

The polishing pads used in the first grinding process are mainly polyurethane pads, commonly known as urethane pads. However, there are cases where non-woven fabric polishing pads (hereinafter referred to as non-woven pads) are used separately. Non-woven pads refer to polishing cloths made by binding short fibers, known as non-woven fabric, with resin, and they are generally available in white. Since non-woven pads are not made solely of resin, they tend to have a lower grinding rate compared to urethane pads, but they have advantages in terms of surface accuracy and ease of handling. *For more details on the column, please refer to the related links.

The "Straight Gauge" that we sell. This product has recently become very popular, but why is it selling? I wondered about this, so I would like to analyze it in the inquiry section. A straight gauge is a device used in the grinding and polishing industry, where multiple dial gauges are installed on a metal flat bar to measure the accuracy of a surface plate. At our company, we measure the surface plate whenever necessary. This is because we believe it is essential to always and accurately understand the shape changes of the surface plate. After truing, after dressing, before processing, and after processing, we compare the changes in the surface plate at each moment to determine how to use the surface plate flatly at all times, whether to process in the forward or reverse direction, whether the position of the work hole is correct based on the wear of the surface plate, and whether the overhang amount is appropriate, among other considerations. *For more details on the column, please refer to the related links.

It can be easily attached and detached to a magnetized flat plate. Compared to conventional free abrasive (grinding sand) grinding processes, it can be processed with stable precision. Precision management is easier compared to free abrasives, leading to improved productivity. There is no wear on the flat plate, so replacement of the flat plate is unnecessary. It significantly reduces waste compared to conventional free abrasives (grinding sand). Since there is no scattering of free abrasives (grinding sand), a clean processing environment can be achieved.
