Large CNC Turning and Milling Center

Friday, August 14th, 2009

The Gear Works is pleased to announce its latest acquisition and installation of world class machining technology: 72″ Giddings and Lewis Vertical Turning & Milling Center. Now, large parts can be turned, milled, drilled, tapped, and inspected in one efficient set-up by utilizing multiple on-board machining functions, such as the 25 H.P. live milling spindle and 12 station tool changer.

A 20 ton overhead crane provides part access to the 80,000 Lb. G&L Turning/Milling center
