Why? Introducing the benefits and development examples of Japanese-made cold pill rolling mills!
The "Pilger mill" rolls by inserting a mandrel into the inner diameter of the pipe and rotating it in a spiral while being subjected to a reciprocating motion by the rolls. It allows for high pressure, contributing to process improvement and yield enhancement. The cold Pilger mills used by major steel manufacturers in Japan adopt a large-scale mechanical cam system, while Sanmitsu offers a compact type with an electronic cam system. We can provide customized machines tailored to the applications and requirements of customers while keeping initial investment costs low. [Sanmitsu's Concept] - Equipment design that minimizes initial investment - High productivity achieved through unique design - High quality (good surface roughness, suppression of waviness) - Labor-saving through full automation and visualization - Joint development with customers - Confirmation of operability with demonstration machines *For more details, please refer to the PDF materials or feel free to contact us.
