The effects obtained by incorporating "groove processing (pitch)" into the grinding pad are as follows: - It allows the grinding slurry to reach the inner circumference of the grinding machine, achieving uniform grinding. - It leads to an improvement in the grinding rate. - The discharge of grinding debris (such as sludge) becomes smoother. - By changing the pitch width on the upper and lower plates, it reduces the phenomenon of substrate and workpiece adhesion. Regarding the groove specifications, you can specify the groove width, pitch width, depth, and type (concave, U-shaped) according to your preferences. *The basic groove type is "grid grooves," but other embossing processes can be discussed. Additionally, "grit hole drilling" is also possible upon request. This can help with cumbersome tasks on-site and contribute to safety management. *For more details, please feel free to contact us.

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. If you have any questions, feel free to contact us.*

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.*

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.

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.

The suede pads we offer come in two types: non-woven fabric base and PET base. The non-woven fabric base pads have cushioning properties in the base itself, resulting in less damage to the workpiece, good conformity to the shape of the workpiece, and the ability to effectively polish the entire workpiece. Additionally, the PET base pads are very precise due to the quality of the PET itself, making them effective for polishing that requires flatness. 【Features】 <Non-woven Fabric Base Pads> ■ The base itself has cushioning properties ■ Good conformity to the shape of the workpiece ■ Can effectively polish the entire workpiece <PET Base Pads> ■ Very high precision of the PET itself ■ Effective for polishing that requires flatness *For more details, please feel free to contact us.

The size of the grinding pads ranges from 1000 to 1400 mm in width and up to around 2000 mm in length, and they are shipped with double-sided tape attached. For medium-sized grinders, it is possible to use a single pad, while for large grinders, sizes exceeding 1800 mm in diameter require the pads to be joined together. Additionally, the upper side must have more than 30 abrasive holes processed. Our company can also perform processing like the one shown in the image, so please feel free to consult us. 【Features】 ■ The size of the grinding pads is 1000 to 1400 mm in width and up to around 2000 mm in length ■ Shipped with double-sided tape attached ■ Medium-sized grinders can use a single pad ■ Large grinders require the pads to be joined together ■ The upper side requires processing of abrasive holes *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.*

In flat grinding, it may be common to perform maintenance on the PAD using a dresser, but surprisingly few places actually measure and manage the values. Due to the characteristics of grinding, there is a tendency for the central area of the reference plate to become more concave, but simply making corrections at regular intervals and for the same amount of time does not truly indicate whether proper maintenance is being performed. By using a straight gauge, it becomes possible to manage the numerical values of the overall shape, making production management very efficient. 【Precision Management Method】 ■1. Establish the reference for the straight gauge (dial gauge) ■2. Measure the reference plate (When measuring the reference plate, use a base set if measuring soft materials) *For more details, please feel free to contact us.

Do you know the suitable particle size for dressers for urethane pads? The way the dresser finishes the PAD surface is crucial for improving quality and yield. In practice, incorporating multiple processes solely into the dresser can be inefficient on the manufacturing floor, leading to increased labor and costs. Therefore, we introduce dressers by selecting a "best of both worlds" particle size. The suitable particle size varies depending on the processing environment, so please feel free to consult us about the appropriate dresser and particle size for your current processing environment. 【Purpose of the dresser】 ■ Elimination of clogging and flattening ■ Accuracy correction ■ Smoothing the PAD surface, etc. *For more details, please feel free to contact us.

When polishing with polyurethane pads using cerium oxide and other materials, it is inevitable that abrasives remain in gaps and holes. The efficiency of the next operation greatly depends on how well the abrasives are removed during the cleaning at the end of the day's work. However, doing this manually can lead to uneven cleaning, and if this accumulates, it poses a risk of shortening the lifespan of the polishing pads. Therefore, we recommend using a brush carrier. Please feel free to inquire whether it can be adapted to your work environment for improved quality and working conditions. 【Benefits of the Brush Carrier】 ■ Other tasks can be performed while cleaning the brush ■ Reduced likelihood of rate decline due to pad clogging ■ Polishing quality has stabilized, leading to improved yield *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.

In double-sided lapping and polishing processes, if the shape of the reference plate or polishing pad deteriorates, it can lead to scratches on the workpiece, worsened flatness, and decreased processing rates.
