We will introduce the differences between swaging and radial forging. Swaging is a processing method that reduces round bars or circular pipes to a desired diameter, also known as rotary cold forging. Radial forging is a processing method that applies force from the radial direction of a hollow shaft using a hammer (die) to induce plastic deformation. At Tsuzuki Seisakusho, we have introduced radial forging equipment to address our customers' challenges. **Features of Radial Forging** - Forging is possible even for thick shafts or shaft shapes with flanges. - Partial warm processing allows for increasing thickness (upsetting) only at the ends. - Areas requiring precision, such as inner diameter splines, can be forged cold. - There is no need to arrange multiple pieces of equipment as with swaging. - Setup time is minimal, and it can accommodate multiple models. *For more details, please refer to the related links or feel free to contact us.*

"Radial Forging" is a forging processing technology that performs position control of the inner diameter core and hammering on the outer diameter for cylindrical components such as hollow shafts, allowing for the formation of complex inner diameter shapes. It enables multi-stage processing in a single operation, contributing to product lightweighting, high strength, and cost reduction. By hollowing out, it is also possible to incorporate additional functions such as internal cooling. It can be processed under conditions suitable for deformation amounts and specifications, accommodating hot, warm, and cold working. It is applicable to various cylindrical components, including rotor shafts. 【Features】 - Multi-stage shapes can be formed in a single operation through NC control of the hammer. - Simultaneous forming of inner and outer diameters is possible. - High precision and low scale are achieved through warm forging. - Capable of handling small lots and short delivery times. *For more details, please refer to the materials or related links. Feel free to contact us with any inquiries.

"Radial Forging" is a forging machine that applies force from the radial direction of the axis using a hammer (die) to achieve plastic deformation. By inserting a core and transferring the inner diameter shape, it is possible to form both the inner and outer diameters simultaneously. Additionally, since it can perform hot and warm processing, it is capable of machining shapes with thick shafts or flanges. 【Features】 ■ Compatible with "hot, warm, and cold" processing, allowing for machining under conditions suitable for the amount of deformation and specifications. ■ NC control of the hammer enables the formation of multi-stage shapes with a single chuck. ■ By controlling the position of the hammering from the outside and the inner diameter core (mandrel), it achieves inner diameter shapes that are impossible with cutting processes. *For more details, please download the PDF or feel free to contact us.
