Cincinnati 6-Axis Gantry Mill set up to do electrochemical grinding

Cincinnati Bridge Mill

LARGE CNC CINCINNATI GANTRY MILL FOR SALE

New Machine – Never Used in Production – Government Surplus 

Currently set up to grind Invar, but could easily be set up to do milling.

Jorgenson Machine Tools has acquired a 6-axis (X, Y, Z, A, B, C axis) CNC Cincinnati Gantry Mill (bridge mill) currently configured to do electrochemical profile grinding.

A tolerance of +- 0.0005″ is maintained within entire envelope.

With a U5 bridge type, this model AR-0137 machine is also equipped with a full enclosure and air handling system.

Purchased new in 2007 by the U.S. Government, it only has 200 spindle on hours (used during install) and features a Seimens 840D control.

It has a travel of 265″ on the X-axis, but being a bridge-style machine the X-axis could be easily extended. It has travels of 160″ on the Y-axis and 48″ on the Z-axis.

It is designed for grinding invar (primarily used for composite molds) as well as other metals.

It can be left with its current grinding head, or we can, as an option, retrofit it to virtually any customer’s machining requirements.

If retrofitted to a 5-axis milling head, the Y travels could be extended (machine has 25′ between X-axis rails).  The Z-axis can also be extended to meet the customer’s requirements.

Call Kyle Jorgenson at 801-554-0683 for more information.

If you have a need for a big HEAVY machine like this, you may never see a deal like this again — we are asking 20% of the original purchase price paid by the Government for this machine (price on request).
