Stepped Bushing Model

A precise 3D CAD model of a stepped cone pipe fitting (Reducer/Bushing) featuring an internal through-bore. This symmetrical concentric design serves as an ideal test piece for multi-axis CNC lathe turning, injection moulding draft verification, wall thickness analysis, and automated DFM check platforms like TIXAN. Key Features Stepped Conical Profile: Designed with a dual-stage exterior consisting of a wide cylindrical base transitioning into a smooth tapered cone for fluid flow dynamics. Concentric Straight Through-Bore: Features a central circular hole extending fully through the part, perfect for verifying core pin deflection and internal bore turning setups. Blended Fillet Edges: Incorporates smooth rounded transitions at the apex to minimize stress concentrations and prevent premature tool chipping during machining.
