Pyöräporaus

Pyöräporaus, a Finnish term, translates to "wheel drilling" or "wheel boring" in English and refers to a specific type of metalworking process. It is primarily used in the manufacturing of rotating components, particularly those with a central bore and an outer rim or flange, such as wheels, gears, and brake discs. The process involves simultaneously machining the inner diameter of the bore and the outer diameter of the component in a single setup, often on a specialized lathe. This technique offers several advantages, including increased accuracy, reduced machining time, and improved concentricity between the inner and outer diameters. By eliminating the need to reposition the workpiece between operations, pyöräporaus minimizes cumulative errors and ensures a higher quality finished product. The tooling and machinery employed are designed to handle the simultaneous cutting of both features, often utilizing multi-axis machines or custom fixtures. While the exact configurations can vary, the core principle remains the efficient and precise creation of a component with two co-axial, machined diameters. This method is particularly beneficial for high-volume production where efficiency and consistency are paramount.
