Achieved a thin-walled shape with an outer diameter of φ39 and a wall thickness of 1mm! Finished with a surface roughness of Ra1.6 using broaching.
We would like to introduce a product example of an internal gear "Titanium Thin-Walled Helical Gear," which is often used in speed reducers and can compactly fit the entire device due to its shape. The outer diameter is φ44.405, with a helical gear MP0.5PA20°84T. It is finished with turning, hobbing, and broaching, achieving a surface roughness of Ra1.6. The outer diameter of the thin-walled section is φ39, realizing a thin-walled shape with a thickness of 1mm. 【Case Overview】 ■ Size: Module 0.5, Outer Diameter φ44 ■ Material: TB480 (Pure Titanium) ■ Application: Aerospace ■ Features - Type 3 is a material focused on strength among pure titanium - Achieved a thin-walled shape with a thickness of 1mm - The inner diameter is processed by broaching *For more details, please refer to the PDF document or feel free to contact us.
