坂上製作所 Company Profile

For machining screw rotors, Sakagami Manufacturing.

Sakagami Manufacturing Co., Ltd. is a pioneer in the industry that creates three-dimensional freeform surfaces through function operations, including calculus, and performs machining using machining centers. We are well-known for processing difficult materials such as turbine blades, rotors, and parts that include three-dimensional freeform surfaces, as well as variable lead screw rotors with changing cross-sections and lead pitches, using materials like SUS304, SUS630, titanium alloys, and Inconel. We also accommodate special aluminum alloys that are essential in aerospace. We have a proven track record in creating NC data for special parts through variable parameter input and providing that system. Sakagami Manufacturing Co., Ltd. implements various proposals to enhance functionality and streamline production through discussions with clients. For example, we are committed to supporting clients who do not compromise on functionality, offering powerful solutions such as quadratic curves instead of arcs, quadratic lead curves instead of constant leads, and function surfaces with theoretical backgrounds instead of mere appearances. We welcome research and development as well as single-item prototypes.
