Emag’s VT 2-4 vertical turning machine is capable of machining shafts as long as 400 mm and ranging to 63 mm in diameter. Workpiece grippers transport the raw parts into the machine and remove them once they have been machined. According to the company, changeover can be accomplished in as little as 6 sec., depending on the workpiece. Four-axis machining enables the component to be machined from two sides simultaneously. The vertical alignment of the workpieces is said to increase process integrity, as the unhindered chip flow prevents clusters from forming in the machining area.
The company will also display its VL2 vertical pick-up lathe for machining small chucked components such as gearwheels, sliding sleeves, synchronizer rings and flanged components.
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.
