We would like to introduce a case study on thin-profile molded chip saws and groove processing at a heat sink manufacturer. The company faced challenges where the grooves of the heat sinks being straight caused distortion in the riveting process, leading to instability in the processed parts. They also wanted to improve cooling performance by narrowing the spacing between the heat dissipation plates and increasing their quantity. To address this, they added an angle to the molded grooves of the riveting parts, stabilizing the shape of the riveting sections. By polishing with a unique special processing machine, they were able to achieve sharper angles than 45°, resulting in the ability to narrow the spacing between the heat dissipation plates and increase their quantity. [Challenges] - Straight grooves in the heat sink cause distortion in the riveting parts, leading to instability in the processed sections. - They want to narrow the spacing between the heat dissipation plates to increase their quantity for improved cooling performance. - They are using carbide metal saws, but the cost burden is significant. *For more details, please download the PDF or feel free to 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.

We would like to introduce a case study on cold saw/cutting processing at a steel trading company. The company had a challenge of wanting to increase the yield from a single round bar, and they were looking for ways to make the blade thinner. Making the blade thinner means that the body also needs to be thinner; however, if the body is made thinner, it can lead to issues such as lateral runout and bending during cutting. Through trial and error regarding the body’s rigidity, flatness, and the cutting angle for smoother cutting, we were able to develop a product that meets their requirements. 【Case Overview】 ■ Challenge: They wanted to increase the yield from a single round bar and make the blade thinner. ■ Our Efforts: - We conducted trial and error on the body’s rigidity, flatness, and cutting angle. - Not only did the yield increase, but the reduction in blade thickness also led to a decrease in chips. - The frequency of changing the drum for collecting chips decreased. - The burden on staff was also reduced. *For more details, please download the PDF or feel free to contact us.

We would like to introduce a case study on PCD cutters/V-cut processing at a building materials manufacturer. The company faced challenges such as wanting to achieve a cleaner finish on the V-groove processing surface and wanting to eliminate secondary processes like sanding after machining. To address this, they changed the material of the cutter body to enhance the rigidity of the cutter. By increasing the number of blades, they were able to reduce the cutting amount per blade, resulting in improved processing surfaces and successfully extending the life of the blades, which contributed to cost reduction for the customer. [Challenges] ■ Wanting to achieve a cleaner finish on the V-groove processing surface ■ Wanting to eliminate secondary processes like sanding after machining *For more details, please download the PDF or feel free to contact us.

We would like to introduce a case study on ultra-hard slitter knives/slitting processing at an EV battery manufacturer. In this company, variations in roundness accuracy occurred due to the effects of fitting, resulting in defects on the machined surface. To address this, by using a unique special jig to bring the tolerance of the blade's shaft hole as close to 0 as possible, roundness in the micrometer range was achieved, thereby resolving the processing defect issue. 【Case Overview】 ■ Challenge: Variations in roundness accuracy due to fitting effects led to defects on the machined surface. ■ Our Approach: - Used a unique special jig to bring the tolerance as close to 0 as possible, achieving roundness in the micrometer range. - The processing defect issue was resolved. *For more details, please download the PDF or feel free to contact us.

We would like to introduce a case study on the introduction of carbide metal saws/dicing processing at a semiconductor and electronic components manufacturer. The company faced challenges in maintaining the shape of the processed surface and cutting width as the number of cutting processes increased, and aimed to improve surface accuracy and tool life. To address this, they switched from dicing blades to high-hardness carbide metal saws, which minimized changes in the shape of the processed surface even as the number of cutting processes increased. [Challenges] - As the number of cutting processes increases, the shape of the processed surface and cutting width change, which they want to maintain as much as possible. - Improvement of surface accuracy and tool life. *For more details, please download the PDF or feel free to contact us.
