The decorative parts of train cars, particularly around the headlights, are crucial areas where the quality of appearance directly influences the overall impression of the vehicle. What we were consulted about this time was a high-difficulty decorative part made of stainless steel with a welded structure, which required that no welding marks be left on the surface at all. The key to our response was the process design based on the assumption of post-welding burn removal and surface roughness management through buff polishing. The weld bead was completely eliminated, resulting in a surface that was uniform and reflective. Honestly, it’s at a level where you might think, "Are we really going this far?" but the team is in a serious mode, looking for further improvements!

In aluminum gravity casting, it is important not only to meet strength requirements but also to focus on comprehensive quality design that includes precision and appearance. Even if there are no issues on the drawings, there are often points that can only be noticed when seeing the actual product during prototyping or mass production preparation. In this project, we adopted a manufacturing process that combines gravity casting and machining, collaborating with casting and machining vendors from the design stage. Three key points emerged that require particular attention. The first is the ejector pin marks. Even if there are no issues in terms of strength, a slight protrusion can lead to an appearance that feels off. The second is burrs. They may not be noticeable immediately after casting but can appear as defects after surface treatment. The third is the management of geometric tolerances. Subsequent processes, such as inserting helicoils, can affect precision, such as symmetry. In gravity casting, prior alignment with a view of the entire process is key to stabilizing quality. If you are considering castings, please feel free to consult with us. *Such efforts are just a small part of what Bandai does on a daily basis.

Bandai boasts an "unwavering procurement capability." This time, we would like to introduce a case where we delivered the "precision single-row cylindrical roller bearing," necessary for spindle prototyping, from a lead time of six months for made-to-order production to just three weeks. Initially, it was deemed impossible to obtain the specified part number, but at Bandai, we reorganized the design conditions (inner and outer diameters, load, and rotation speed) and proposed an alternative: the **"precision multi-row cylindrical roller bearing"** that meets the same specifications. By collaborating with the manufacturer (NSK), we confirmed compatibility through technical calculations and were able to meet the short lead time for prototyping. Bearings are critical components where the balance of dimensions, precision, and rigidity is essential. Even when making an "alternative proposal," we do not rely solely on catalog values; instead, we work together with the manufacturer's technical department to derive reliable solutions that our customers can adopt with confidence. *This kind of response is just a small part of what Bandai does on a daily basis.

"I received a bearing that is different from the model I ordered...?" Such voices can be heard here and there in the bearing procurement field. Behind this, there are often **"manufacturer-specific symbols" that are not listed in the catalog.** For example, models like "6900ZZ1CM" or "6900ZZ1NXR*" may seem familiar at first glance, but symbols like "1" or "NXR" are not included in the catalog, which can confuse newcomers and customers. While veterans might brush it off as "Oh, that's a common one," it can be quite troublesome for those who are not used to it. This can lead to procurement mistakes or inquiries. That’s why we at Bandai make sure to thoroughly support you with such "confusing aspects." If you ever think, "This model looks unfamiliar..." please feel free to reach out to Bandai.

A request for rod-shaped machined products from a customer. When we asked multiple lathe machining companies in the "Hometown Processing Network" for estimates, the responses were almost all "processing not possible." Upon confirming the reasons, many expressed that "the geometric tolerances are too strict." Indeed, while the specifications may be precise on paper, factors such as manufacturing difficulty, cost, and lead time significantly impact actual processing on the shop floor. This time, after confirming the customer's intentions, we adjusted the tolerance specifications, which ultimately allowed for smooth and realistic processing responses. The professionals in design and those in processing—bridging the gap between them, aligning intentions, and connecting to the site in the optimal way—this is one of the important roles of Bandai. *Such responses are just a small part of what Bandai does daily.

The request from the customer was for high-precision machining of copper pins, reducing from φ6 to φ2, with M4 tapping included. At first glance, copper may seem like an "easy-to-machine material," but due to its softness and tendency to deform, along with strict tolerances, general lathes cannot handle it, making precision machining with NC lathes essential. However, for extremely small diameters like this, chucking on an NC lathe itself is difficult. A partner who previously processed φ4 SUS material also responded that they could not accommodate this condition. Nevertheless, we did not give up and found a machining company within the "Hometown Processing Network" that has specialized technology for small diameters, successfully leading to an order. Copper material × high precision × extremely small diameter—this project made me realize that a comprehensive knowledge of materials and a strong machining network are necessary to address all these factors. *This kind of response is just a small part of what Bandai does every day.

• Processing Contract

We received a request from a customer to perform additional processing on a standard bevel gear from a certain gear manufacturer. The "material" section of the drawing listed the model of the standard product, and both our company and the processing contractor proceeded with the prototype based on that information. However, after delivering the prototype, we were pointed out by the quality control representative that "the hardness is different." In a hurry, we rechecked the drawing and found that there was a clear hardness specification exceeding the standard product's hardness range mentioned separately in the drawing. This was a moment of reflection for us as professionals, caused by the assumption that "there should be no problem since it's a standard product" and a lack of thorough verification. Fortunately, we were able to address it with heat treatment, but it reinforced the idea that drawings should not only be reviewed at the beginning but should be examined thoroughly until the end. We will ensure that we do not waste this experience and will be diligent in checking every detail moving forward. *This kind of response is just a small part of the initiatives that Bandai engages in daily.

Heat treatment is a very important factor in the production of processed products. However, it is often difficult to distinguish between good and bad products based solely on their appearance, so it is essential to have a precise understanding of the process. If heat treatment is ordered without sufficient understanding, it could lead to significant problems later on. Our company has also had bitter experiences in the past where issues arose from heat treatment. Therefore, our company has conducted several internal study sessions, and our employees have a good understanding of the content and risks associated with heat treatment. Now, we will explain this in an easy-to-understand manner using the example of gears. *For detailed content of the blog, please refer to the related links.
