Deep Hole Drilling for Couplings and Universal Joints
Couplings and universal joints are components that connect rotating shafts. They often need through-holes for weight reduction, lubrication, or assembly access. The drilling work is similar to general shaft work but with some specific requirements. I have drilled components for industrial couplings, automotive driveline U-joints, and heavy equipment shaft connections. The tolerances and volumes vary widely across these applications, which means I adjust the process for each one. Coupling Hubs Coupling hubs are the parts that mount on the ends of shafts. They typically have a through-bore that matches the shaft diameter and may have additional cross-holes for keyways or set screws. ...
