High-speed operation with an electronic cam system. "Cold Pilger Mill" that requires no foundation work.
Manufacturing of precision pipes for gas piping and lightweight automotive parts, with the ability to adjust various rolling conditions! Compact and high-performance metal tube cold processing machine.
The "Cold Pilger Mill" performs rolling by inserting a mandrel into the inner diameter of a pipe and rolling it back and forth with a reciprocating roll while rotating it in a spiral manner. It allows for high pressure and contributes to process improvement and yield enhancement. It also improves uneven wall thickness and surface roughness. Additionally, there are two-roll and three-roll configurations that can be selected based on efficiency and precision. This product is expected to find new applications in various fields, in addition to intermediate and finishing processes associated with the high-strength requirements of automotive parts. 【Features】 ■ Significantly reduces labor compared to conventional tube stretching methods ■ Allows for adjustment of various rolling conditions (rolling stroke, material tube feed pitch/angle, one-way rolling or reciprocating rolling) ■ Electronic cam system achieves compactness and energy efficiency, with numerical control capability ■ The TDN system realizes productivity that is 150% higher than conventional methods *From the [Download] section, we are currently providing materials that describe the differences between the cold pilger rolling method and the tube stretching method, along with the product catalog.
