Continuing from the last time, I will explain the characteristics of the first-angle projection and third-angle projection. The space is divided into four quadrants by two orthogonal planes, with the first, second, third, and fourth quadrants named in a counterclockwise manner starting from the upper right. The drawing methods that capture objects in the first and third quadrants are called first-angle projection and third-angle projection. Now, I will explain why the arrangement of component drawings differs. *For detailed content of the column, you can view it through the related links.

The other day, one of our sales employees asked, "Regarding the pulley in the drawing, is it possible to manufacture it using the rolling pulley processing machine from ○○ Seiko?" The content of the drawing involves an FC material and a multi-stage pulley structure, which cannot be produced with a rolling pulley processing machine. Given that the lot size is not large, it is difficult to use mold forming, so we provided a quote based on cutting processing. By the way, are you familiar with "rolling pulleys"? It might not be a term you hear often. This time, I would like to explain "rolling pulleys." *You can view the detailed content of the column through the related links.

We would like to introduce a case where we received an urgent request from a client in Ehime Prefecture to manufacture 150 types of processed parts within three weeks. Our company held a strategy meeting with processing contractors. Since sheet metal processing was the most common, we first visited Company A, which specializes in press and laser processing. We divided the processing assignments while consulting with the person in charge. For the ASSY parts, which seemed challenging, we decided to request Company B from the Shimane Processing Network, known for saying, "Leave it to us for prototypes." Although there was a possibility of delays due to heavy snowfall, we managed to complete the project, and we received praise from the client, stating, "Despite the short delivery time, we are fully satisfied not only with the quality but also with the cost." **Summary** - The Shimane Processing Network has close relationships and is concentrated in neighboring areas, allowing us to respond to requests that may seem impossible at first glance. - Our strength lies in our ability to handle everything from single-item processing to ASSY processing through welding with a sense of speed. *For more details, please refer to the PDF document or feel free to contact us.*

In the explanation of "UXIMO" that I introduced last time, the term "planetary gear" came up several times. It is a component that plays an important role in the reduction mechanism, and this question comes from our new employee, O-san, who frequently brings it up: What exactly is a "planetary gear"? To explain "what its purpose, features, and mechanism are" in an easy-to-understand way for the new employee, I have summarized the information, so please take a look. *For detailed content of the column, you can view it through the related links.

The planetary gear mechanism consists of spur gears and functions as a reduction, reversal, and acceleration mechanism by fixing one of the three gears: the sun gear, the ring gear, or the planetary gear. This time, we will introduce the roles of each gear in the case of "reduction with the ring gear fixed." *For detailed content of the column, please refer to the related links.

In this final installment, I will discuss "Increasing speed and reversing through the fixation of sun gears and planet gears." If you have read from the previous installment to this one, I believe you will see the full picture of the planetary gear mechanism. I mentioned in the last installment that "to reduce speed, you change the number of teeth on the gears." This is the same for other combinations as well. In other words, it can be said that "gear shifting and reversing are done through combinations of gears without changing the meshing speed of the gears." *For detailed content of the column, you can view it through the related links.

In the past, there was an exchange with a processing company regarding sheet metal materials. This processing company delivers products made from blast furnace materials to customers, but there was a consideration for using electric furnace materials due to a certain opportunity. "Blast furnace" and "electric furnace" are terms that we often see in newspapers and other media lately, but I wasn't quite sure what the specific differences were, so I decided to look into it. First, the major difference between the two is the "refining method." Additionally, the "raw materials associated with the refining" are different. Now, let me explain the characteristics of each. *For detailed content of the column, you can view it through the related links. For more information, please feel free to contact us.*

Everyone, do you accurately understand the meaning of welding symbols? I believe that processing companies that actually perform welding understand them, but how well do sales representatives from technical trading companies like ours comprehend them? If a sales representative receives a drawing from a customer and can immediately say, "The key point of this weld is..." it would be very reassuring, wouldn't it? However, isn't it often the case that it just ends with, "They are welding..."? Depending on the material and application, is arc welding, TIG welding, or even fiber laser welding necessary? Isn't it common for it to end with something like, "Let's get a quote from that processing company for this type of welding"? *You can view the detailed content of the column through the related links.

What is lost when something becomes hard? It is toughness. Toughness is like the ductility that a material possesses. When hardness is increased, this ductility is compromised. What happens when toughness is compromised? Let’s take diamond, the hardest mineral in the world, as an example. While diamond has a very hard image, this is only effective against wear and scratches; it can easily shatter when subjected to impact, such as from a hammer. *For more details on the column, please refer to the related link.

I would like to introduce a case where a client suddenly revealed their plan to launch a highly confidential project unrelated to their main business. The shocking content was their desire to create their own "machine tools" for drilling and cutting materials such as metals. Leveraging our extensive experience in developing machine tools, we decided to create a simple test machine to identify issues. Next, we produced Prototype No. 2, reflecting the improvement proposals, and as a result of data collection, we achieved significant improvements, realizing a roundness of less than 3 microns, which was set as the standard value. The actual machine was deployed in the client's processing department and is now operating as a device responsible for part manufacturing. 【Request Details】 ■ Content: A client who was manufacturing entirely different products is creating machine tools they have no experience with. ■ Request Items: Completion of the project, including the role of advisor regarding the design and manufacturing of machine tools. ■ Points of Caution: Due to the confidential nature of the project, we will proceed with utmost care to ensure that information does not leak within the client's company. *For more details, please refer to the PDF document or feel free to contact us.

During discussions with an automation equipment manufacturer, we caught wind of the information that "a certain component is experiencing early wear and requires countermeasures, but we are struggling to find improvement solutions." Here, we would like to introduce a case where we responded to the client's request for extending the lifespan of conveyor rollers within a limited budget. We recalled that during a project aimed at extending the lifespan of cutting tools, we had formed a metal coating with properties harder than the tool itself on the surface, and decided to proceed with surface treatment considerations. We consulted with Company A, a processing contractor renowned for its expertise in surface modification technology, and under the theme of "creating low-cost rollers specialized for wear resistance," both companies discussed the manufacturing process. Next, we explained the manufacturing process to the automation equipment manufacturer and moved on to prototype evaluation. As a result, a low-cost and high-performance product was completed. [Results were favorable] - By using inexpensive materials for the roller body and applying superalloy only to the surface, we achieved low cost and wear resistance. - Simultaneous grinding and finishing of the sprayed area and the bearing sections at both ends of the roller resulted in a high-performance product with minimized rotational runout. *For more details, please refer to the PDF document or feel free to contact us.

Here is an example of a request for solving a difficult problem from an automation equipment manufacturer. We received an inquiry from an automation equipment manufacturer, with whom we have worked on many processed products, regarding a processed product to be used in a new development project for a leak testing device. The request was, "To ensure that the O-ring is securely held, the groove for the O-ring on the in-roller shaft needs to be sloped. Is this feasible?" We selected a processing company, explained the response details to the automation equipment manufacturer, and proceeded with prototype evaluation. Each iteration of the prototype increased the difficulty, but we finally resolved the challenging issue of air leakage on the third attempt by steepening the slope to 24 degrees. By meeting the customer's needs and facilitating cooperation between the automation equipment manufacturer and the processing company through our company, we were able to solve the problems faced by the client. [Challenge] We want to add a groove for inserting an O-ring to prevent air leakage in the in-roller section of a flanged shaft, but if the groove shape is straight, a phenomenon occurs where the O-ring is pulled by the pressed parts during repeated air leakage tests. *For more details, please refer to the PDF document or feel free to contact us.

During a visit to a car parts manufacturer we have been working with, we discovered a large quantity of used punches. A 200L drum was filled with used punches measuring Φ8×27mm. Upon inquiry, we learned that the quality of the punches currently being purchased is unstable, leading to variability in tool life and making it difficult to calculate replacement timing, which has caused confusion. We promptly introduced the designer of the punches and conveyed the situation on-site. Although the designer was at a loss, they explained a rough outline of a proposed solution based on their previous experience with custom machining, which led to the response, "Please go ahead with Bandai!" When we proposed an improvement plan using metal film coating to keep costs down, we received feedback that they had previously attempted this but experienced early breakage instead. From that information, we hypothesized that the heat generated during the coating process might be the cause and began to take measures. As a result, the previously unstable usage count of the punches increased to an average of 15,000 shots, achieving a stable lifespan that is approximately three times longer. *For more details, please refer to the PDF document or feel free to contact us.

We would like to introduce a case where an agricultural machinery manufacturer was perplexed by the request for "quality stability" and "stable supply" of the extremely rare part known as the handling body. From the sales know-how and information accumulated in our company, we caught wind that a processing company in Shikoku was manufacturing similar parts, and we approached that processing company for consultation. When we conveyed the current situation, we received advice that in order to enhance quality stability in mass production, dedicated jigs should be prepared. We communicated this to the agricultural machinery manufacturer and produced a prototype. We decided to implement automatic production using robots. Following the advice, we also manufactured dedicated jigs based on those specifications. Additionally, considering the transportation efficiency from Shikoku to our Shimane sales office, we created a "two-story transport rack." The prototype performed well, achieving an astonishing quality stability with a handling blade entry and exit amount of less than 0.02 mm. We successfully cleared the challenges of "quality stability" and "stable supply," and by redesigning the part and automating production, we also succeeded in reducing costs. *For more details, please refer to the PDF document or feel free to contact us.*

There are four main methods of heat treatment. The toughness we discussed last time is imparted by performing "tempering." It is often said "quenching and tempering," and it is common to perform these together to give steel surface hardness and toughness. Annealing and normalizing are not frequently used in the processing we mainly handle, but the photo of the handle shows that annealing was performed to soften the iron and bend it. The base part of the bend has undergone annealing. *For more detailed information, you can view it through the related links. Please feel free to contact us for more details.*
