大府精巧 List of Products and Services

The other day, we received an inquiry about finding a place to re-sharpen shear blades. The dimensions of the blade are "2060mm." Our sharpening machine, the "Toyo Blade Sharpening Machine," has a magnetic flat surface length of "2000mm"... which is not long enough... When we explained this to the customer, they said, "If you can somehow manage it, I would like you to do it," and with the customer's consent, we proceeded with the re-sharpening. At Obu Seiko, we have experience in re-sharpening shear blades several times, but this was our first time handling something this long. However, since the re-sharpened product was quite thick, we were able to manage the re-sharpening somehow. We are relieved to have been able to assist the customer. *For more details, you can view the blog through the related link. Please feel free to contact us for more information.

While the cutting performance is fine when using a new cutter, the sharpness (finish) and life (blade retention) inevitably deteriorate after re-sharpening, leading the customer to give up and purchase new ones each time. They inquired whether re-sharpening could be an option to reduce costs. *For details on the solution and effects, please refer to the PDF document or feel free to contact us.

We would like to introduce four examples of blade re-sharpening and manufacturing carried out by Ohbu Seiko Co., Ltd. 【Summary of Introduced Cases】 In the case of "Re-sharpening of Specially Shaped Blades," we improved re-sharpening quality through outer diameter precision and grinding wheel selection. We restored performance to like-new condition and achieved cost reduction. In the case of "Re-sharpening of Blades for Brush Processing," we performed re-sharpening of rotary blades. The edge precision and finishing condition of the rotary blades improved dramatically. In the case of "Custom-Made," we manufactured blades for producing rasps. We utilized flat grinding technology and wire electrical discharge machining equipment. For the "Discontinued Carbide Replacement Tool," we produced a single item from a sample. After determining that it could be manufactured with our equipment and technology, we provided a quote and received an order for production. *For detailed case information, please download the PDF or feel free to contact us.
