We would like to introduce a case study in response to the inquiry regarding the high wear rate and frequent blade replacements of existing circular blades when cutting rolls of copper foil film at various stages of processing. We propose a carbide circular blade made from ultra-fine particle alloy, featuring a double-edged design. By altering the cutting angle at the start and the angle at the blade's base, we have reduced the impact on cutting performance even as the blade wears, enabling stable cutting even with composite materials. As a result, we have achieved more than double the lifespan compared to conventional blades, thereby reducing the frequency of replacements. [Case Overview] ■ Issue - Existing circular blades wear out quickly, leading to high replacement frequency. ■ Proposal - A carbide circular blade made from ultra-fine particle alloy with a double-edged design. *For more details, please download the PDF or feel free to contact us.

We would like to introduce a case study in response to the request to minimize the irregularities on the cutting surface during the process of cutting thin film used for solar panels into long lengths. We selected a long-lasting, high-hardness carbide circular blade and adjusted the blade angle and thickness to suit the workpiece, allowing for cutting without applying unnecessary stress to the film. Since the sharp edge is maintained even during continuous cutting, the cutting surface can be kept clean. This method can also be applied to other functional films (such as PET and EVA). 【Case Overview】 ■ Challenge - To minimize irregularities on the cutting surface during the process of cutting thin film into long lengths. ■ Processing Details - Selected a long-lasting, high-hardness carbide circular blade. - Adjusted the blade angle and thickness to suit the workpiece, allowing for cutting without applying unnecessary stress to the film. *For more details, please download the PDF or feel free to contact us.

We would like to introduce a case in which we received an inquiry from a medical device manufacturer regarding the desire to "cut a silicone tube with a diameter of less than 1mm, without burrs, and at an angle." The tubes used for catheters are extremely thin and are inserted into narrow internal pathways such as blood vessels, making them critical components that require high safety standards. An angled cut expands the cross-section, so the thickness of the blade and the angle of the cutting edge are directly linked to the quality. In response, we proposed a thin-blade design of a carbide round blade, which achieved an extremely smooth cutting surface while suppressing deformation of the tube. Additionally, the use of carbide material significantly improved the durability of the blade. 【Case Overview】 ■ Challenge: To cut a silicone tube with a diameter of less than 1mm, without burrs, and at an angle ■ Proposal: Thin-blade design of a carbide round blade ■ Processing Details: Achieved an extremely smooth cutting surface while suppressing deformation of the tube ■ Result: The use of carbide material significantly improved the durability of the blade *For more details, please download the PDF or feel free to contact us.

We received an order for round blades for slitting processing for food protection sheets, and we would like to introduce a case we produced. After much trial and error, we decided to use round blades for this slitting process and opted for carbide materials to enhance durability compared to conventional methods. Considering the installation dimensions of the machine and the size of the slits, the final diameter was reduced to less than 20mm. For reference, a PET bottle cap has a diameter of about 28mm, making this even smaller. 【Case Overview】 ■ Purpose: Slitting processing for food protection sheets ■ Processing Details: Use of carbide materials ■ Product: Ultra-small round blade with a diameter of less than 20mm *For more details, please download the PDF or feel free to contact us.
