The Eldorado M75-30 gundrilling machine from Kays Engineering 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" (19mm) and a maximum drilling depth of 30" (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. Eldorado machines are designed and manufactured in the United States.
