Development of a Practical Laser-guided Deep-hole Boring Tool

A practical laser-guided deep-hole boring tool with a diameter of 110 mm is produced. The tool consists of a counter-boring head, actuators for its attitude control, an active rotation stopper and a laser system for detecting its attitude. Performance of each component is examined. As a result, the stopper can move toward a rotational direction by an inchworm mechanism. The tool attitude can be controlled by the actuators and laser system. The trial experiments show that the practical laser guided deep hole boring can be performed by using a coupling.
