The company offers four models of gang tool lathes. The spindle diameter capacity of the relative models go from 1”, 1 3/8”, 1 ¾” and the largest model is 2” bar feed capacity through the spindle. The horsepower of the models go from 5 hp, 7.5 hp, 10 hp, and the largest is 15 hp. The axis motors also increase in size with each model.
The smaller two models, GT-ISL-25 and GT-ISL-35, are the classic small footprint C-axis gang tool lathes, ideal for the introduction of live tools and bar feeds for secondary operations, or high rate production work. We are also adapting these machines with vibratory bowls and automatic loading systems that make this selection an ideal option for fastener production or other types of automated part production applications.
The two larger models of gang lathes, GT-ISL-45 and GT-ISL-50, provide X-axis travel of 18.5” and have a much lower center height than earlier models of gang tool lathes. As a result of the lower center height and travel, the company can now add a turret directly to the machine table to provide a combination of a gang tools along with an eight-station or 12-station turret. We can also offer a driven tool turret for heavier milling drilling live tool operations for very complex part production on a single-spindle designed machine.
Editor PickRobotic Cell Cuts Cycle Time, Improves Part Quality
Sew-Eurodrive Inc. worked with Okuma America’s authorized systems dealer, Gosiger Automation, to design an automated cell that includes an automatic, magazine bar feeder that loads 6-ft. lengths of barstock into the machine. The shop also switched to an Okuma twin spindle, twin turret turning center so all of the machining operations are completed in one setup, thus eliminating additional fixtures and operator intervention. The resultant system reduces cycle times and requires much less operator involvement. As a result, production time per part was more than cut in half – from about 5 minutes to 2 minutes, 20 seconds.
