Gundrilling Machine's "Counter-Rotation" Design Improves Accuracy

The Eldorado M75-30 gundrilling machine features a new design for its counter-rotation fixturing assembly.

During the gundrilling process, the workpiece is held in a fixturing assembly that rotates the part in the opposite direction of the gundrill rotation. This "counter-rotation" of the workpiece improves the accuracy of the gundrilling process. The new fixture design includes a gear motor assembly that is more powerful and durable than the previous design.

The Eldorado M75-30 has a maximum gundrilling diameter of 0.75 inches (19 mm) and a maximum drilling depth of 30 inches (762 mm). The machine features a box way design as opposed to linear guide ways. This results in superior vibration damping, extended tool life, and improved surface finish.
