Robotic welding for precise assembly

In fabricating the drop link, we use robotic welding to join sheet metal and tubing, focusing on tight tolerances between welded components. Ensuring parallelism between both sheet metal pieces and tubes, as well as perpendicular alignment between sheet metal and tube, poses challenges that require careful oversight. To maintain these tolerances, we utilize specialized welding jigs and checking fixtures to guarantee each part aligns with precise parallel and perpendicular specifications.

CNC Boring for Bearing Bores

To achieve the strict R7 tolerance on the bearing bores, CNC boring is employed to meet high-precision requirements. This dual-tube boring process demands consistent parallelism between both tubes, adding complexity to the machining process. These tolerances are critical to ensuring the drop link's reliable alignment, dependability, and fitment under heavy loads.

Surface Treatment: Sandblasting and Electrocoating

For enhanced durability and aesthetics, the drop link undergoes a two-step surface treatment: sandblasting, followed by electrocoating. Sandblasting prepares the metal by removing impurities and creating an optimal texture for coating adhesion, while electrocoating ensures a uniform protective layer. This combination offers increased resistance to wear and environmental elements, extending the product's lifecycle and maintaining its appearance.
