坂上製作所 List of Products and Services

Sakagami Manufacturing Co., Ltd. is a company primarily engaged in the machining of mechanical parts. It is a pioneer in the industry that creates three-dimensional freeform surfaces through function operations, including calculus, and performs machining using machining centers. The company is well-known for processing difficult-to-cut materials such as turbine blades, rotors, and parts that include three-dimensional freeform surfaces, with varying cross-sections and lead pitches, made from materials like SUS304, SUS630, titanium alloys, and Inconel. It also caters to special aluminum alloys essential for aerospace applications. There is a proven track record in creating NC data for special parts using variable parameter input and providing that system.

This is a machined unequal lead screw rotor used in SUS304 food machinery. On the left side, spoon-shaped teeth are arranged in the equal lead section, while trapezoidal teeth are arranged in the equal lead section on the right side. The central unequal lead section features a smoothly changing tooth profile. The spoon-shaped teeth are designed to feed while cutting through the material block with strong force, and the trapezoidal teeth apply significant pressure. The diameter of the central axis gradually increases towards the right side, allowing for stronger feed pressure. We can also accommodate requests regarding the tooth profile shape, shape changes, and variations in lead. 【Features】 ■ Used in SUS304 food machinery *For more details, please contact us or download the catalog.
