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.

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.

Are you using a DP-equipped correction carrier (pad dresser) somewhat casually? There are points that should change depending on the type of PAD when using a DP-equipped correction carrier. Main usage purposes include: - Dress - Improvement and prevention of clogging - Uniformity of PAD condition - Rate increase - Yield improvement However, the basics of polishing lie in the precision of the reference plate. The DP-equipped correction carrier is used to correct the precision of that reference plate (PAD) and to improve and maintain its surface condition, but currently, there are few customers focusing on the precision of the PAD. From a different perspective, this can be a point of differentiation. There are two main ways to improve the surface condition of the PAD: - Correcting the overall precision of the reference plate (truing) - Correcting and improving the surface condition of the reference plate (dressing) DP-equipped correction carriers can also be broadly divided into two types based on their purpose: - Ring type (truing + dressing) - Inset (dressing) Why not check what type should be used for current challenges (such as edge droop and rate improvement) and daily management, and what the current state is? If you consult us, on-site support from technical staff is also possible.

When you hear "custom," does it evoke a cool image? If you are using a cast iron DP-equipped correction carrier, it is possible to customize it to make it look cool and to facilitate precision management. Our correction carriers use a resin carrier, making them very lightweight compared to cast iron, and they feature DP on both sides of the carrier. The lightweight design is expected to improve "safety" and "workability," but the biggest feature is the customization tailored to the polishing environment. The correction of the PAD needs to change the DP arrangement and particle size depending on the processing environment and the hardness of the PAD. By customizing to fit the polishing environment, it is also possible to significantly reduce correction time. There are many cases where a dressing operation that used to take 1 to 2 hours has been shortened to about 5 to 30 minutes depending on the customer. In addition to time savings, we can effectively correct the PAD's precision, leading to improvements in edge droop and polishing rates, among other achievements in yield enhancement. We will propose correction carriers tailored to your current challenges and needs, so please feel free to consult with us. Depending on the type, you can use the correction carrier free of charge for up to one month.

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?

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.

The most common feedback from customers who have adopted DP correction carriers and pad dressers is the customization tailored to their processing environment. Typically, customers often purchase fixed pattern products or use those that come with their equipment, but is it suitable for their equipment? On the other hand, our products build unique patterns that incorporate both the basic pattern and the customer's requests. Changes made so far include: - Material changes (selecting materials considering corrosion and strength) - Pattern changes (constructing the best pattern based on precision, rate, and free test results) - Granularity changes (selecting the appropriate grit based on pre-tests for the current PAD) We create products with considerable effort that other companies may not want to undertake. * Adjustments to the thickness of various materials (carrier, DP) and the construction of immediately usable DP surface conditions, etc. Please download the materials to check the features of the DP correction carrier.

Regarding the improvement of work efficiency for DP-equipped correction carriers, this time we will discuss the reduction of work burden. First, what comes to mind when considering work burden? If it's a 9B size, you might not feel it too much, but what about 16B size or 28B size? Each piece can be quite heavy, right? - It needs to be carried by two people. - It can only be moved with machinery. - Installation is difficult. These are common concerns. The larger the work burden, the more discouraging it becomes. The solution to this is weight reduction. One of the features of our DP-equipped correction carriers is their lightweight design, and many customers notice the advantages and reduction in work burden that come from this lightness. Please download the materials to check the weight comparisons by size, etc.

In discussions about the correction of grinding pads (urethane-based and suede-based), the terms "dressing" and "truing" often come up. The differences are as follows: Dressing: Adjusting the surface condition Truing: Adjusting the overall precision of the pad This time, we will talk about dressing, and the surface conditions sought in dressing include: Uniform roughness, ensuring opening diameter, and removal of dirt. However, the conditions and duration for dressing are often "carried over" from previous practices. Additionally, is the dressing tool properly managed? In many cases, it is not. Managing the condition of the tools is important. That is why our DP-equipped correction carriers often have many examples of time savings and are frequently appreciated for their ease of management.
