When it comes to inspection, I think many people have the image of a job that involves checking whether something is made according to the drawings. Of course, that is not incorrect, but when you actually do it, there are many situations where it feels like it’s not just about simply confirming numbers. The most challenging aspect of inspection is determining how to judge tight tolerances. When the measured result is close to the limit, it can be difficult to decide whether it is acceptable or not. Even if the value falls within the range, the results can vary depending on the measurement method and the criteria used, so careful judgment is necessary. This is especially true when using a three-dimensional measuring machine; the results can change depending on which surface is used as a reference and where the measurements are taken, even for the same part. *For more details about the blog content, you can view it through the related links.

One of the common causes mentioned is "distortion." Distortion may be a bit difficult to understand, but it refers to the phenomenon where the shape of a part slightly deforms due to the influence of materials and processing. For example, with aluminum parts, they may appear fine while clamped (fixed), but the moment the clamp is removed, they can warp slightly. Additionally, due to heat during processing or internal stress, the shape can gradually change after processing. *You can view the detailed content of the blog through the related links.

Even with the same drawing, just changing the materials used can greatly affect the ease of processing and the results of measurements. This time, I would like to briefly introduce the differences I have actually experienced regarding aluminum, stainless steel, and iron, which are commonly used on-site. First, regarding aluminum, while it is lightweight and easy to process, I feel that it is a material that easily warps. Even if it looks fine while clamped, there are moments when it slightly bends as soon as it is released, and the values can change depending on the measurement conditions. Additionally, it is prone to scratches, so care is needed when handling it. *For more detailed content of the blog, you can view it through the related links.

When it comes to product inspection, it's easy to focus solely on measuring dimensions, but the state before measuring and the handling after measuring are also very important. For example, parts immediately after processing may have oil or dirt on them. If measurements are taken in this condition, there is a possibility that incorrect values will be obtained. Therefore, it is essential to thoroughly remove any oil and dirt from the surface before inspection. *You can view the detailed content of the blog through the related link.

The newly introduced equipment is characterized by its ability to process multiple surfaces at once, leading to changes in the workflow compared to traditional processing methods. Previously, it was necessary to set up for each surface to be processed, but now there are more instances where multiple processes can be done with a single setup. As a result, the number of setups has decreased, which I feel has contributed to increased work efficiency. *You can view the detailed content of the blog through the related link.

At first, I thought, "If it's the same thing, the values should be the same," but in reality, the results can vary depending on the measurement conditions, and I feel the depth of testing. For example, the way products are placed and secured, as well as the reference point for measurement, can lead to differences in values. Additionally, the number of measurement points and their locations can also change how the results are perceived, and recently, I have come to realize once again that "how to measure" significantly impacts the results when using three-dimensional measuring machines. *You can view the detailed content of the blog through the related links.

At Nabesei, we engage in metal processing such as aluminum and stainless steel, and one of our features is our ability to handle "small lot processing of various types." Small lot processing refers to the processing of various types of products in the necessary quantities. Depending on the product, there may be cases where we need not only mass-produced items in the hundreds or thousands but also units in the range of a few to several dozen. Additionally, we often receive inquiries about creating prototypes, jigs, or additional processing with the request of "first, we want to produce a small quantity." When observing the actual site, it is clear that we are not just continuously processing the same product, but rather responding to a variety of drawings and products on a daily basis. *For more details, you can view the blog through the related link.

At Nabesei, we perform metal processing using machining centers and lathes, accommodating various materials such as aluminum and stainless steel. I am responsible for inspection, and what I feel while seeing various products every day is that each product is made with great care. Not only in processing but also in inspection and measurement, we proceed with the thought of "how can we evaluate more accurately," ensuring that we thoroughly check even the smallest details while creating products. *For more details about the blog, you can view it through the related links.

When people think of Kawasaki City and Yokohama City, they may have an image of residential areas and commercial districts, but in fact, these regions have been active in "manufacturing" for a long time. Nabesei continues to engage in manufacturing in the Kawasaki-Yokohama area, performing metal processing using machining centers and lathes. Through my work in inspection, I see various products every day, and I often witness the careful processing and measurement that takes place on-site, feeling the strength of local manufacturing. *For more details about the blog, you can view it through the related links.

When it comes to measurement, there is an image of setting it on a measuring device and checking the values, but in reality, the results can vary depending on the conditions prior to that. For example, if the product has oil or dirt on it, or if the way it is placed or secured changes, the measurement results can differ. Additionally, depending on the material, there may be slight distortions when it is fixed compared to when it is not. Recently, while using three-dimensional measuring devices, I have increasingly felt that not only "how to measure" but also "under what conditions to measure" is important. *For more details, you can view the blog through the related link.
