Apparatus and method for accurate countersinking and rivet shaving for mechanical assembly operations

摘要: The apparatus and method includes a spindle portion which holds cutting tool. drill is initially moved forwardly of pressure foot the apparatus. then along with to clamp mechanical assembly. A thrust control arrangement produces reduction on tool holder such that as assembly being clamped, contacts workpiece remains stationary while moves forward complete clamp-up. positions tip surface are recorded compensation made apex position stroke, using previously determined reference relative workpiece.
