神谷機工 List of Products and Services

Round knives and slitter knives are also used in the manufacturing of lithium-ion batteries and electronic components, requiring extremely strict polishing finish precision. Our unique ultra-precision polishing technology enables the production of high-precision edge surface roughness and micron-level thickness tolerances. In the case of large-diameter round knives, we have succeeded in brazing with a special ultra-hard material, allowing for the creation of eco-friendly knives that eliminate chips, serving as an alternative to saw blade-shaped tools. 【Features】 Round knives that can cut materials such as films, paper, and insulation for food while reducing chips and minimizing material loss. They are introduced in numerous production sites as cutting tools that not only reduce costs but also consider the environment. ● For more details, please contact us.

We would like to introduce a case study of large-diameter carbide circular knives (Eco Knives) and slitting processing at an insulation material manufacturer. We received a request to solve the dust problem caused by cutting with a chip saw, and we considered redesigning the blade shape to a knife configuration for production. The carbide was brazed to the outer circumference of the circular knife, but initially, there were many instances of chips coming off. However, with the development of a special brazing technique, this issue was improved, and by measuring the brazing strength for each blade, we were able to stabilize the product. As a result, both the dust problem and yield improvement were resolved simultaneously. [Customer's Challenges] ■ We want to solve the dust problem caused by cutting with a chip saw. ■ We want to improve yield. *For more details, please refer to the related links or feel free to contact us.
