Aluminum Alloy CNC Machined Motor Mounting Bracket

This asymmetric metal structure features a large central bore and side dual-ear flanges, typically serving as a mounting base for servo motors, stepper motors, or gear reducers. The main body accommodates the motor shaft extension or bearing seat through the central through-hole, while the flange plates extending from both sides are equipped with counterbored mounting holes. These secure the drive unit firmly to the equipment frame or slide table. This integrated design effectively ensures the coaxiality and connection rigidity between the power source and the transmission mechanism.

The core of manufacturing such irregular structural parts lies in controlling the relative positional accuracy of multi-face features. The roundness of the central inner hole and its perpendicularity to the side mounting surfaces directly impact the smooth operation of the motor, preventing wobble after assembly. The positional tolerance of the bolt hole pattern on the side flanges is also a critical control point to ensure interchangeability with standard motor mounting dimensions. Given the tendency of aluminum materials to deform, clamping solutions are optimized during processing to eliminate dimensional drift caused by stress release. Deburring processes are strictly controlled to prevent sharp edges from affecting assembly fit.

Leveraging a cluster of Taichung and Huashuo brand machining centers at our Ningbo factory, we efficiently complete precision manufacturing involving milling, boring, and drilling/tapping composite processes. Using high-precision CNC equipment, we achieve stable forming under single or multiple clamping setups, ensuring geometric tolerances between features meet drawing requirements. Combined with inspection tools such as profile projectors and roughness profilometers, we strictly verify key mating dimensions. We support non-standard customization based on customer-provided 2D/3D drawings, flexibly adapting to materials like aluminum alloy and stainless steel. Surface treatments such as anodizing and sandblasting are available to meet the delivery standards for lightweight structural components in the automation equipment and robotics industries.
