What happens here
Connecting rods are often machined from steel forgings. A significant portion of the material is removed during a 'profiling' operation to achieve the general shape, followed by boring processes to prepare the rods for subsequent assembly. The grain flow in forged steel rods is crucial for strength and controlled during the forging process. In contrast to pistons, connecting rod production can involve more operations, especially for steel rods, due to the need for fasteners and other intricate features. After machining, connecting rods undergo processes like deburring and honing to achieve precise dimensions and smooth finishes, followed by washing and inspection before approval for delivery.
Goal: Manufacture connecting rods, including profiling, boring, and finishing operations.
