Even though I understand, I can't help but want to close my eyes at the small holes in the cart path. If it clearly needs repairs, then there's no choice, but I completely understand the feeling of wanting to request repairs just for a small hole, even if it means stopping operations. However, golf carts are more susceptible to the effects of holes and bumps due to their small tires, making vibrations feel more intense. If that hole can be repaired to a level where "it's fine for carts to pass" within about an hour of starting the repairs, wouldn't you want to try it? For partial repairs of holes that eliminate customer travel stress without stopping operations, I recommend "Hekomi Flat Takumi." First, please take a look at the link below to see how it looks after repairs and how solidly it becomes!

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. For inquiries about testing and customization, please contact us.

Edge roll-off... also known as "edge roll-off," is actually a challenge that one encounters when performing flat polishing at least once. The causes of this edge roll-off can be narrowed down to a certain extent. 1. Hardness, elasticity, and thickness of the pad 2. Precision of the pad 3. Processing conditions 4. Dressing unevenness Among these, issues related to pad precision and dressing unevenness are common in the polishing industry, and it is often the case that adjustments to processing conditions or pad replacements are made to address these problems. However... to be honest, it's quite a waste. Using our pride, the DP-equipped correction carrier from Yachiyo Micro Science, it is often very easy to make corrections! If you are struggling with edge roll-off in polishing, please feel free to consult with us.

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.

• Wafer processing/polishing equipment

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?

• Wafer processing/polishing equipment

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.

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.

• Other abrasives

Microparticles such as precision abrasives (abrasives) may physically aggregate in water due to intermolecular forces and charging effects. This aggregation can lead to the formation of coarse abrasive particles, which may cause scratches, scuffs, and changes in concentration. To prevent this physical aggregation, one method is to coat each particle (abrasive grain) to prevent physical aggregation between particles. By using coatings to prevent physical aggregation, it can also lead to improved dispersion of slurries, suppressing the aggregation and adsorption between particles. Please try the additive "EVERFLO," which is expected to improve and enhance polishing performance simply by mixing it into polishing slurries. Expected effects from the addition of EVERFLO: - Improved dispersion - Suppression of scratches and scuffs - Increased lifespan (stabilization of polishing ability) - Improved cleanability *Note* When used in silica slurries, there is a possibility of gelation, so please confirm in advance whether gelation occurs.

However, whether treatment is possible depends on factors such as particle size, so we cannot say that any material can be treated. The treatment situation also varies depending on the type of coagulant. Here is a guide on how to confirm whether treatment is possible. 1. Check the original particle size If it is around 80 nm, there is a possibility of treatment. If it becomes finer than that, treatment becomes significantly more difficult. 2. Confirm the coagulation effect First, check the effect as it is. If treatment is possible, that’s fine; if it’s difficult, move on to the next step. 3. Dilution Dilute while the coagulant is added. Check the effect while performing dilution and adding the coagulant. Dilute boldly to about 5 to 10 times and confirm at what dilution there is an effect. The alkalinity of colloidal silica wastewater can interfere with coagulation treatment, so it is also important to start with neutralization treatment in such cases. After neutralization treatment with sulfuric acid bands, coagulation treatment may significantly reduce the amount of coagulant used. First, please check the effect with a free sample or consider our free wastewater treatment test.

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.

I will explain the usage points of the alkaline type "Mizusumairu," which can treat highly alkaline wastewater such as concrete slurry and tool washing water with a single agent, based on my previous experiences. Point 1 - Stir well The powder coagulant works most effectively when stirred well. Please note that the recommended stirring method varies depending on the amount of water to be treated. Manual treatment... Stirring machine, Notch tank treatment... Submersible pump Point 2 - Be careful not to over-add. The alkaline type "Mizusumairu" can neutralize and coagulate with one agent, but if too much is added, the treated water may become acidic, so please add it while checking the pH value. * Please refer to the guideline for the amount to be added. * pH checks should be done using a pH meter or pH test strips. Point 3 - Please dilute if the moisture content is low. If the moisture content of the target water is low (for example, if it is very dirty and thick), treatment may not proceed, so please dilute with water to ensure sufficient moisture content. By paying attention to these points, you can achieve better treatment results.

• Water treatment equipment

"Water Clear (Alkaline Type)" is a powdered coagulant that can perform neutralization and coagulation treatment in one step. Water used to wash tools made with cement and mortar shows strong alkalinity and contains residues of cement and mortar. Typically, neutralization and coagulation treatments are carried out separately, but for wash water of about several tens of liters, neutralization is a very delicate and difficult process. In such cases, "Water Clear (Alkaline Type)," which can complete both neutralization and coagulation with a single agent, is recommended.

• Other consumables

"Oil Flock" is a powdered coagulant that can treat wastewater from cerium oxide polishing. There are times when wastewater from spot tests accumulates to several dozen liters, making it difficult to process. In such cases, performing coagulation treatment for each batch of polishing wastewater can reduce the burden on treatment facilities and lead to cost savings. Oil Flock is a powdered coagulant that can remove up to 99% of suspended solids (SS), with minimal pH fluctuation before and after treatment, making it very user-friendly.

• Other consumables

Coagulants used in construction and civil engineering can also be applied to other purposes. Here are some examples where coagulants can be used effectively. For instance, wastewater generated in facilities such as chemical manufacturing and food processing contains various solids and organic matter. By adding coagulants, it is possible to aggregate the fine suspended particles in this wastewater, thereby improving water quality. Additionally, for the purification of ponds and lakes, coagulants can be used to aggregate and settle suspended solids and organic matter, enhancing the clarity and cleanliness of the water.

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.

• Other abrasives

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.

• Other abrasives

In wastewater treatment involving cerium oxide (ceria) and zirconium oxide (zirconia), there are cases where coagulation treatment using polymer coagulants does not work well due to differences in the inflow concentration of abrasives. This is often not due to the capability of the polymer coagulants, but rather a result of insufficient neutralization treatment or primary treatment, indicating a need for countermeasures. The "Decontamination Tab" is a solid coagulant that can achieve sufficient coagulation effects on its own, but it also serves as an auxiliary agent in the aforementioned cases. 【Features】 ■ Treatment is possible with just one agent ■ No need to adjust the amount added (just soak) ■ Can be used both as an auxiliary agent and as a coagulation treatment agent ■ Can also be used as a sedimentation promoter, making it more effective when longer sedimentation times can be taken *For more details, please feel free to contact us.

The "Oil Flock" that we handle is a powdered coagulant capable of treating wastewater containing black smoke. Wastewater containing black smoke can appear pitch black and be difficult to treat depending on its concentration, but once it is understood that it can be treated with a coagulant, effective treatment is possible simply by adjusting the dosage. Testing of the treated water is necessary, but as long as the water quality of the treated water meets the discharge standards of each municipality, only the coagulated material needs to be disposed of, and the treated water can be discharged. [Features] - Treatment is possible with just one agent - The viscosity of the coagulated material is low and has good dewatering properties - Coagulation and sedimentation can occur in a short time - The coagulated material is of a certain size, making it easy to recover *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.*

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 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.
