Stama America’s MC 726/MT-2C twin-spindle turn-mill is suited for automotive, fluid power, medical and other applications in which parts needs to be milled and turned in production operations. Each of the machine’s two independent spindles moves on a traveling-column assembly and supports an independent swivel table, one of which acts with a bar-feeder mechanism. Workpieces are introduced to the turning spindle and transitioned by a conveyorized gripper assembly to the milling indexer. The workpiece is then fed to the milling spindle before exiting the work area.
The two cutting operations enable complete six-sided machining. The machine is said to provide twice the speed of a conventional turn-mill in a smaller footprint. One part can be milled while another is turned, which increases overall production, the company says. The machining center is the latest iteration of the company’s Tandem concept turn-mill centers.
