BURRLESS FLEXIBLE TRACK DRILLING SYSTEM AND METHOD HAVING COUNTERWEIGHT TOOL BALANCING SYSTEM

摘要

A burrless, flexible track drilling system employing a counterweight tool balancing subsystem. The counterweight tool balancing subsystem provides essentially a "weightless" feel to a machining subassembly of the system that carries a drill and an electromagnet. This enables an operator to move the machining subassembly vertically with only a very minimal degree of effort being required. The machining subassembly also includes a plurality of lifting subassemblies that aid the user in lifting and lowering the electromagnet away from and toward a pair of panels on which a drilling operation is being performed. This also significantly reduces operator fatigue and contributes to a highly ergonomic system.
