We are delighted to present the GT-7 gang tool lathe. This machine has a 1.37" spindle bore and a small footprint. The chips exit the machine from the right side of the lathe. This model gang lathe is an excellent platform for automation. We are confident that you will find this product a versatile, flexible, and reliable addition to your company’s manufacturing capabilities. Our single-piece heavy casting is the culmination of years of experience in machine tool manufacturing and offers the best features for gang tool and turret lathe construction.
