"Deburring Punching Process" is a processing technology that achieves 100% shear surface using a new blanking method. In recent years, fine blanking presses, which provide precision shear comparable to cutting (such as gears), have become mainstream. However, this requires specialized equipment, leading to higher processing costs, and deburring must be performed in subsequent processes. Therefore, we improved our current shear surface enhanced blank (90% shear surface). We developed a deburring punching technology that achieves 100% shear surface using general-purpose press equipment. Currently, only round shapes are available, but we will be prototyping other shapes in the future. 【Features】 ■ 100% shear surface with general-purpose press equipment ■ Achieves deburring punching process ■ No specialized equipment required ■ Low processing costs ■ No need for deburring in subsequent processes *For more details, please refer to the PDF document or feel free to contact us.
