ZPS America’s six-spindle lathe features 51- to 67-mm bar capacity and is designed for continuous or series production of precision-turned parts. A solid base casting increases rigidity and stability.
The machine includes six frontal slides with as many as 142 working strokes, six cross-slides, four compound slides with clamping and a bar stop in the sixth station. An independent cam controls each slide, and stroke is adjustable on the rocker arm of the corresponding drive. The machine is available with spindle speeds ranging from 200 to 3,200 rpm, depending on material type and size.
Designed for precision, safety and reliable operation, the machine features four safety clutches to prevent the slides from overloading. A Hirth coupling provides spindle drum locking for concentricity, repeatability and precision. The machine is equipped with a barstock guide, optional automatic bar loaders and bar magazines for unattended operation.
Other options include an NC drive of the pick-up spindle; bar stock feeding and clamping in the third station; attachments for high speed drilling, reaming, tapping and broaching; and multi-spindle drilling heads on the frontal slides.
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.
