Designed for Quick Installation and Removal

Convert your standard Eldorado Mega 50 or Mega 75 for use as a counter-rotating gundrilling machine.

Counter-rotating your workpieces when machining on-center holes drastically improves straightness and concentricity. A 1.62" ID hollow spindle lets you machine long workpieces from both sides on a short stroke machine, reducing tooling expense and increasing the capacity of existing equipment.

Standard GD series drill bushings are still used when gundrilling with a counter-rotating workpiece. Chucks include master jaws—standard commercially available soft jaws and other tooling can be used. No special proprietary accessories are required.

The complete kit is specifically designed for quick installation and removal, for use when jobs require the increased precision of the counter-rotating process without the need to dedicate a machine only for this purpose.

The counter-rotating chip box insert locates on the machine's existing master bushing with no additional alignment required. The motorized headstock engages the key-slot on the machine table and is clamped in place. The headstock position is adjustable via a leadscrew drive through a right-angle gearbox.

A junction box is provided which mounts on the machine to be prepared for the counter-rotating headstock. After the initial power and emergency stop connections are made (schematics included), a quick-change locking connector is attached to the headstock.

On-site installation and training are available. For complete Eldorado machine rebuilding and precision alignment, refer to our Web page Eldorado Gundrilling Machine Remanufacturing.
