Manufacturing Methods of Splined Shafts
The manufacturing of splined shafts involves various machining processes, each suited for specific applications and materials. Here are some common methods:
Broaching
Broaching is a machining process that uses a toothed tool called a broach to carve out material in a single pass. This method is efficient for producing both internal and external splines, ensuring high precision and a smooth finish.
CNC Milling
CNC milling employs rotary cutters to shape a workpiece, specializing in spline cutting. This technique is adaptable for complex spline geometries and guarantees designs with impeccable detail and tight tolerances.
Hobbing
Hobbing is a gear-cutting process that uses a hobbing machine and a cylindrical tool called a hob. Known for its high accuracy and speed, hobbing is especially suitable for external splines.
Shaping
Shaping employs a single-point cutting tool that moves linearly against a stationary workpiece. This traditional method is effective for crafting internal splines, achieving intricate profiles with high precision.
Extrusion
Extrusion involves pushing material through a die to form a specific cross-sectional shape. While often associated with plastics, this technique is vital for creating metal internal splines.
