Bandai is trusted by many customers as a "spring professional" with a proven track record in proposals for both coil springs and leaf springs. In particular, coil springs are precision components where the load varies finely based on wire diameter, coil diameter, winding direction, and number of turns, yet they are often scrutinized for cost as consumables. During the prototype stage, setup costs and delivery times with NC machines become challenges, but Bandai has established a system that allows for "hand-winding" by skilled artisans. We flexibly respond to special specifications that cannot be wound with NC machines and to short-term prototype requests, receiving production orders from spring manufacturers nationwide. Bandai's strength lies not only in "processing equipment" but also in leveraging "technology and people." If you are facing issues with coil springs, please feel free to consult us. *This type of response is just a small part of the efforts that Bandai engages in daily. Please take a look at the value we can provide to our customers.

• Spring

The "leaf spring," which is essential for agricultural machinery, may not stand out in appearance, but it is a high-performance component that requires durability, the ability to handle repeated loads, and a stable spring constant. At Bandai, we collaborate with specialized processing companies that have a track record of working with major agricultural machinery manufacturers, including companies K, Y, and I, in the production of leaf springs. Our manufacturing system is characterized by the ability to complete all processes in-house, from material selection to press mold production, blank processing, bending, and hardening. This integrated management system enables us to respond quickly from mold setup to mass production and to meet strict quality and delivery management standards. Additionally, for parts that require precision, we also perform wire cutting and complex shape press processing, allowing us to make optimal proposals tailored to product characteristics. If you are facing issues with leaf springs for agricultural machinery, please consult with Bandai, which has a proven track record, trustworthiness, and responsiveness. *This type of response is just a small part of the efforts that Bandai engages in daily.

Have you ever looked at a drawing and thought, "Can't this be processed with machining?" In reality, if you make a mistake in selecting the processing machine, it can have a significant impact on cost and delivery time. In this blog, we will focus on the differences between 3-axis and 5-axis machining centers and discuss the "key points for determining processing methods." For example, consider a shape like a "round groove" on the outer circumference—at first glance, it may seem like machining could handle it, but the "φ" symbol on the drawing indicates dimensions based on lathe processing. It requires the ability to correctly assess the compatibility between the equipment and the shape. How to interpret the constraints of the site that are not visible in the design and the strengths and weaknesses of the machines—this is the first step toward making accurate processing proposals. Understanding the equipment and collaborating with the processing site helps prevent things from going "off the drawing." This content is something we would like not only young professionals but also those in design and technical departments to read! *Such responses are just a small part of the efforts that Bandai engages in daily. Please take a look at the value we can provide to our customers.

"I thought standard machining was 5-axis" — This remark from a new employee during on-the-job training prompted us to organize the differences between 3-axis and 5-axis machining machines and the criteria for their selection. 5-axis machining machines have a configuration that adds two axes of tilt and rotation to the three axes of the spindle, making them strong in multi-surface machining and complex curved surface machining with one chucking. On the other hand, there are many cases where 3-axis machining is sufficient depending on the machining content, and choosing 5-axis can lead to excessive investment in terms of both man-hours and costs. It is necessary to select equipment according to the differences in mechanisms such as simultaneous 5-axis and indexing 5-axis, as well as the workpiece shape and precision requirements. The "Hometown Processing Network" not only provides equipment specifications but also offers optimal matching proposals based on the machining content! *This kind of response is just a small part of the efforts that Bandai engages in daily.

"Impressed by the beautiful finish" "This quality at this price? Isn't it too cheap?" — The surprising feedback we received was for a canning product made from SUS304 thin plates (φ400) with spot welding. The drawing only specified spot welding, but we proposed a unique solution by first applying TIG welding as a distortion countermeasure and then adding spot welding as a supplement, achieving both strength and appearance. The value of this "extra effort" resonates with customers who are particular about quality. What are the reasons behind our processing know-how that can handle small lots and high difficulty, as well as our price competitiveness? This is a must-see case for those struggling with SUS canning or considering VA/VE design! *Such efforts are just a small part of what Bandai does every day.

Is it too good to be true to be 'cheap, fast, and good'? — No, there are proper 'reasons' for it. We will delve into the 'secret of the low cost' of the 'Hometown Processing Network' that we introduced earlier. The key lies with H, a professional in welding and prototype processing. By maximizing their strengths in can manufacturing, they optimized costs through reduced setup times and improved processing efficiency. Identifying the 'strengths and weaknesses' that cannot be discerned from equipment lists or websites and ensuring optimal matching is the true essence of Bandai. We would like to present practical examples that those who want to maintain high quality while keeping costs down should definitely read. *Such efforts are just a small part of what Bandai does on a daily basis.

Are you familiar with "5 Whys Analysis"? It is a method of identifying the "essential cause" rather than just the superficial cause by repeatedly asking "why?" five times in response to troubles or challenges. In the past, when I was in charge of a medical device manufacturer, I had a bitter experience where the lack of depth in this analysis led to ineffective recurrence prevention measures. Even answers that seem reasonable at first glance can turn out to be off the mark when explored from different angles. Nowadays, companies like Toyota are utilizing "5 Whys Analysis" not only in inventory and brand strategies but also in various situations, highlighting the demand for "thinking skills" beyond just technical fields. This time, I will focus on this "5 Whys Analysis" and share tips for applying it to recurrence prevention and business improvement! *For more details, you can view the blog through the related link.

"Can you bend this?" This is a common inquiry we receive regarding the processing of steel pipes and round bars, but there are many underlying conditions such as bend radius, total length, diameter, wall thickness, tolerances, lot numbers, and whether there are subsequent processes involved. At Bandai, we assess the optimal method from multiple processing techniques, including NC pipe benders, press brakes, single-action presses, and burner heating, and provide proposals accordingly. Even in cases where bending as per the drawing is not possible, we can respond with proposals that are **"not constrained by processing,"** such as welding and assembly. Additionally, assembly support involving drilling, end processing, and welding can be handled seamlessly through our **"Hometown Processing Network."** From prototypes to mass production and complex processes, please feel free to consult us! *Please note that this type of response is just a small part of what Bandai does on a daily basis.

Tough pitch copper—this material, which is particularly difficult to process even among pure copper, has seen an increase in prototype requests. The reason lies in the characteristics sought by customers. It is not the high thermal conductivity, but rather the high surface roughness requirements aimed at "light reflectivity." However, this copper is soft, ductile, and prone to copper powder adhering to cutting tools, making the processing conditions extremely strict. When a surface roughness of Ra0.1 is required, meticulous attention is needed to avoid processing deformation and ensure finishing quality. Our company can provide proposals and responses that take into account processing know-how and inspection processes. In fact, we handle it with extremely careful processes, such as separately processing dedicated samples to prevent inspection scratches. If you are struggling with fine processing of pure copper, please feel free to consult us. Our accumulated know-how and "Hometown Processing Network" will surely be of assistance to you. *This type of response is just a small part of the initiatives that Bandai engages in daily.

We are the authorized sales agent for the manufacturer "Nissei," whose main product is gear motors. This time, we would like to introduce the **new product "UXIMO"** that was highly recommended by the Nissei representative, as it is very appealing! UXIMO is a high-rigidity, large-diameter hollow type reducer, a new model released in 2021 aimed at joint axis applications. It employs a planetary gear structure utilizing an eccentric oscillating crankshaft internally. This resolves the issues of low rigidity and shaft diameter limitations that have been challenges in conventional reducers, greatly expanding design flexibility. Moreover, the delivery time is as short as one month. While competing manufacturers take over six months, we have a significant advantage in terms of speed of implementation. The pricing is also comparable to competitors, and through our agency, it can be even more advantageous...!? If you are interested in robots, AGVs, positioners, or similar products, please feel free to contact us! *For more details, you can view the blog through the related link. For further information, please download the PDF or feel free to reach out to us.*

• gear

One of the particularly important keywords in the high-rigidity reducer "UXIMO" from Nissay, which we introduced last time, is "planetary gear." Immediately, a question came from within the company—specifically from our new employee, Mr. O. "What is a planetary gear?" Even if many have heard of mechanical terms, there are likely many who do not fully understand them. Therefore, this time, we have gently explained the purpose and characteristics of planetary gears. Why are planetary gears chosen in situations where a compact reduction mechanism is required? By grasping that "reason," the "structural edition" we will introduce next time will surely become clearer! *You can view the detailed content of the blog through the related links. For more information, please download the PDF or feel free to contact us.

• gear

In the previous installment, we introduced the theme "What is a Planetary Gear?" in an easy-to-understand manner, covering its purpose and features. This time, as a continuation, we will explain the structure of the planetary gear mechanism and how the reduction is achieved. The planetary gear mechanism consists of three gears: the sun gear, the planet gears, and the ring gear. By fixing one of these, we can create movements such as reduction, reversal, and acceleration. This time, we will focus on the representative "reduction structure with the ring gear fixed" and explain how each gear takes on power and what roles they play. Particularly noteworthy is the complex motion of the planet gears, which both "rotate" and "orbit." This movement is the key to enabling a compact and highly efficient reduction mechanism. By understanding the workings of planetary gears, your perspective on design and selection should change as well. Please be sure to read to the end! *For more detailed content, you can view it through the related links. For more information, please feel free to download the PDF or contact us.

• gear

In the previous content, we explained the purpose, features, and basic structure of the planetary gear mechanism. This time, as a conclusion, we will introduce the mechanisms of "speed increase" and "reverse" that occur when the sun gear and planetary carrier are fixed. The operation of the planetary gear mechanism changes significantly depending on which component is fixed and where the input and output are taken. In this presentation, we use still images to clearly organize the movement of the gears and their relationships while explaining the structural points. The planetary gear mechanism can control not only the reduction but also the rotation speed and direction. Please take a look at the high applicability hidden within its simple structure. *For more detailed content, you can view it through the related links.

"We want to utilize the mold we are currently using and have it processed externally." We receive many such inquiries at Bandai. However, since the molds are designed to fit the customer's press machine, they often cannot be used if simply transferred to a different factory. Differences in die height and bolster position can lead to issues and risks of mold damage. In response to customers who say, "We don't want to create a new mold," Bandai has carried out numerous transfers through modifications of existing molds. The modifications are done by craftsmen from the "Hometown Processing Network," who are well-versed in AMADA press machines. They ensure a fit with minimal adjustments, achieving low costs and short delivery times. We have a track record of transferring hundreds of molds. If you want to make the most of your existing molds, please feel free to consult with us! *This is just a small part of the initiatives that Bandai engages in daily.

"Do you handle neodymium magnets?" From that single inquiry, Bandai's new challenge began. The customer had been purchasing neodymium magnets as components to be integrated into their equipment through an e-commerce site, but they were troubled by the complexities of accounting processes and the risk of stock shortages. Starting next fiscal year, the usage is expected to increase dramatically to 5,000 units per year. At this point, "stable supply" becomes an absolute requirement. As a trading company, we believe that "if goods are being distributed, there is always a solution." Based on this belief, we discovered a reliable company that specializes in the manufacturing and sales of neodymium magnets. We established a procurement system focused on corporate sourcing that cannot be obtained through e-commerce. *This type of response is just a small part of the efforts that Bandai engages in daily. Please take a look at the value we can provide to our customers.*

• magnet

I previously mentioned that we alleviated the customer's concerns and received an order for neodymium magnets, but when customers request a quote, their expectations are not limited to just stable supply. Furthermore, it is not always the case that customers request quotes only from our company; there are often instances where they reach out to multiple competitors. Therefore, this time I will convey "what is the most important thing to consider when requesting a quote." *You can view the detailed content of the blog through the related link.

The other day, shortly after 5 PM, we received a request for a quote for five processed items from a customer. The requester is a major printing manufacturer with whom we had a connection at a previous exhibition. Among the items, the one that caught our attention was a can structure using a 2m SS400 square pipe. The requirement for the perpendicularity of the end face was a strict tolerance of within 0.05mm, and there was also a specification for baked paint. Since it involves multiple processes, coordination and planning are crucial for preparing the estimate. Furthermore, the deadline for the response was the next morning—making it a race against time. In the limited time available, I would like to share how we proceeded with the response. *This kind of response is just a small part of what Bandai does on a daily basis.

The request for a quote for processed products that include large sizes, strict tolerances, and coatings adds the challenge of time. Although it was initially deemed "difficult to accommodate," this led to the creation of connections between processing companies. Thanks to the prompt communication with another processing company, both the meetings and the quoting process advanced rapidly. This incident reaffirmed the value of a locally rooted processing network. *Such responses are just a small part of the efforts that Bandai engages in daily.

When replacing engines overseas, a common issue that arises is "non-standard keyway dimensions." Recently, we received an inquiry from an agricultural machinery manufacturer regarding **a keyway machining with a width of 4.76mm, which is an inch standard**. In the prototyping stage, it can be addressed with wire cutting. However, when considering mass production, selecting the appropriate method becomes crucial. Taking into account processing costs, delivery times, and reproducibility, it is necessary to find the optimal solution among broaching, slotting, and wire cutting. In this article, we will introduce how to approach such "special dimension keyways," including key points for selecting processing methods and examples of our responses. *Please note that such responses are just a small part of the efforts that Bandai engages in daily.

The other day, one of our sales employees consulted about the contents of a drawing. "Regarding the pulley in the drawing, is it possible to manufacture it using the rolling pulley processing machine from ○○ Seiko?" The drawing specifies a structure of an FC material multi-stage pulley, which cannot be produced with a rolling pulley processing machine. Since the lot size is not large, mold forming is difficult, so we proceeded with a quote based on cutting processing. By the way, are you familiar with "rolling pulleys"? It might not be a term you hear often. *You can view the detailed content of the blog through the related link. For more information, please download the PDF or feel free to contact us.*

• Belts and pulleys

"I want to make it lighter, but I can't compromise on strength." "I want to keep costs down, but aluminum is expensive." There is an answer to this pulley design dilemma: "rolled pulleys." By laser cutting SPCC material and forming a V groove through rolling, we achieve lightweight, high rigidity, and low cost. Additionally, we can accommodate key grooves and boss welding, making it widely usable with general V belts and resulting in zero initial costs. It has been adopted in many fields, including agricultural machinery manufacturers, and has a wealth of proven results. Now is the time to reconsider the conventional "norms." If you are struggling with design, VA/VE, or cost reviews, please take a moment to read this. *This is just a small part of the initiatives that Bandai engages in daily.

To the purchasing managers who are in such trouble, my proposal is metal 3D printing that can be shaped regardless of form or LOT. I promptly requested a quote from a processing company that owns a "metal 3D printer" and received a response. "It's so expensive!" The price is several times that of the current products. With that amount, you could purchase multiple lost-wax items. However, the issues at hand are "delivery time" and "inventory management hassle." Price should be secondary. *You can view the detailed content of the blog through the related link. For more information, please download the PDF or feel free to contact us.*

• 3D Printer

Recently, I received an inquiry from a purchasing manager regarding the replacement of lost wax products. The lead time for the lost wax products currently being procured is long, and even when checking the delivery date, there are no accurate answers. It seemed that the purchasing manager was under maximum stress. Additionally, the manufacturing lot is also a source of concern, as they are ordering more than the required amount in a single order for inventory management. *For more details, you can view the blog through the related link.

Our sales representative had questions regarding the processing details. The drawing specifies a heat-treated steel with a size of φ500 and a half-ring shape weighing 30 tons, with multiple long holes and tapped holes. The first processing method that comes to mind for this drawing is machining. However, machining has poor material yield and results in high costs. Upon reviewing the conditions, it is noted that there are several repetitions per year with a quantity of 100 pieces per lot, so the customer considers this a part for which they want to reduce costs. *For more details, you can view the blog through the related link.

"The electroless nickel plating on stainless steel peeled off during assembly..." This report caused a temporary uproar at the site. The SUS product was intentionally plated considering the sliding with the counterpart parts and its appearance, but due to an unexpected trouble, there was a possibility of a line stop for the customer. Where is the cause? In fact, a specific "property" unique to stainless steel was influencing the situation. This time, we will share the pitfalls of electroless nickel plating on SUS materials and points to prevent peeling based on actual experiences. *Such responses are just a small part of the efforts that Bandai engages in daily. Please take a look at the value we can provide to our customers.

• stainless

"Stainless steel is resistant to rust, but plating does not adhere well." Do you know the reason for this? In fact, it is largely related to the **"oxide film" unique to stainless steel**. While this film contributes to the high corrosion resistance of stainless steel, it also acts as a **"barrier that reduces adhesion"** during the plating process. If the processing conditions are not correct, it can lead directly to early peeling of the plating. In this instance, based on real examples of electroless nickel plating peeling, we will explain **"why did it peel off?" and "how can we prevent it?"** from the removal of the oxide film to the surface treatment (nickel strike). *Please note that such measures are just a small part of the initiatives that Bandai engages in daily.

"Could you please do it as soon as possible, somehow?" Among the drawings that arrived, there was a particularly eye-catching part. The material was FCD450—meaning cast iron. The quantity was small, just 30 pieces, but the shape was complex, and the drawing date was ten years ago. Feeling a slight unease, I confirmed with the customer, and as expected— "Actually, the current processing company has lost the mold..." Normally, it would be unavoidable to have a long lead time to remake the mold. However, the drawing specified **±0.005 dimensional tolerance and Ra0.2 surface roughness**, and furthermore, that area was the "cylinder sliding part." In other words, it was a high-precision part that required honing. At Bandai, we replaced everything with cutting without using a mold, and by collaborating with a honing-specialized processing partner, we achieved the shortest possible lead time. Even without a mold, and even with strict precision— Our **"Hometown Processing Network" at Bandai** can respond to those "troubles." *Please note that this kind of response is just a small part of what Bandai does every day.

Recently, we have seen an increase in requests for press processing. Could it be due to the impact of the weak yen leading to a return to domestic production? With that said, this time I would like to introduce a press processing company that BanDai takes pride in. Press processing can be broadly divided into single-stroke presses and progressive presses. At our company, we can confidently provide both types of requests with "affordability and quality." First, in the case of single-stroke presses, the most sought-after aspect is "affordability." Customers pursue lower product costs, even if it means incurring high initial costs for molds. *For more detailed information, please refer to the related links.

The other day, I received a message from a processing company in the "Hometown Processing Network" saying, "We are considering introducing a fiber laser welding machine, but do you still have the previous project?" The "previous project" refers to a request we received from a customer a few months ago, which was a mass production project for 100 lots at a desired price of 10,000 yen per unit. It was a very attractive project.

"Do you know anywhere that can perform machining on C1100 (pure copper)?" This inquiry marked the beginning of the current project. While there are many vendors that can handle brass materials, C1100 is in a different category. Due to its high conductivity and softness, machining it is challenging, and the number of vendors capable of doing so is very limited. Furthermore, this time, in addition to lathe work, machining, and brazing, a high level of difficulty is required with the addition of "water tightness testing." Typically, it would be necessary to individually request each process from multiple vendors that specialize in each type of machining. However, Bandai utilizes its "Hometown Processing Network" to select and coordinate suitable processing vendors for each step, establishing a system for integrated support. Customers can simply place their orders with Bandai, entrusting the entire complex process of division of labor to us. *This type of support is just a small part of what Bandai does on a daily basis.

What was required for the brazed products was the assurance of water tightness. To confirm the inspection method using measuring tools, a one-way trip of three hours to the customer's site was initiated by Bandai's determination. However, the overseas processing companies that were considered responded that "water tightness testing is not possible." While they were confident in their quality, differences in inspection methods and philosophies became a barrier. Still, we did not give up. Pure copper processing was entrusted to overseas vendors, while water tightness testing was assigned to a reliable domestic partner. Bandai connected both, creating a breakthrough with a hybrid approach of "processing: overseas × inspection: domestic." What the customer needs is for the "products as per the drawings" to arrive on time. The flexible combination power of Bandai's "hometown processing network" meets that expectation. *This type of response is just a small part of what Bandai does on a daily basis.

The **full flat horizontal press "FLAT-250LM"** is a piece of equipment that responds to the demand for "more freedom in bending" at prototype production sites. It achieves three-dimensional bending and accommodates small lots of various types, which were difficult with vertical presses, through its horizontal structure and multi-point die-fixed table. It can flexibly process materials from round bars to pipes and thin plates, demonstrating its strength particularly in prototype and development applications. With a pressing capacity of 10 tons, it is easy to handle and helps reduce die costs, providing significant cost advantages. The FLAT-250LM offers a new option for "free bending," which was challenging with conventional pipe benders and press brakes.
