1results about How to "Reduced heat transfer capability" patented technology

This utility model discloses a stator blade machining milling cutter with convenient heat dissipation, relating to the field of milling cutter technology. It includes a tool holder with a machining head fixed to its bottom end. The machining head has a cooling assembly inside, comprising an annular sleeve rotatably connected to the curved outer wall of the tool holder, with a connecting pipe on one side of the annular sleeve. This utility model utilizes coolant flowing in an annular groove to cool the machining head, extending its service life. Simultaneously, the coolant is sprayed out from a cooling groove at the rear end of the tool holder, further improving the cooling effect and reducing heat transfer between the tool holder and the machining head. This rapidly removes cutting heat, preventing dimensional deviations caused by softening or thermal deformation of the blade material due to high temperatures, thus improving the blade's profile accuracy. Furthermore, the coolant sprayed from the cooling groove can directionally flush away chips, preventing long chips from entangled in the machining head and reducing scratches on the blade surface during machining.
